Application of Thick Copper PCB

Manufacturing Processes of Thick Copper PCB Board

1. Design Preparation: Use CAD software to define circuit patterns, ensuring trace widths and spacing comply with thick copper (≄3 oz/ftÂČ) current-carrying requirements.

2. Material Selection: Choose substrates with high thermal stability (e.g., FR-4, polyimide) and copper foils tailored to target thickness (4 oz/ftÂČ to 20 oz/ftÂČ).

3. Copper Deposition: Apply electroplating or etched-foil processes to achieve uniform copper layers. Thick copper requires controlled plating currents to avoid voids or uneven distribution.

4. Pattern Etching: Use alkaline or acidic etchants to remove excess copper. Thick copper demands longer etching times and specialized chemistry to prevent undercutting.

5. Lamination: Stack prepreg layers and copper clads under high temperature/pressure. Thick copper boards may require sequential lamination to manage resin flow and avoid delamination.

6. Drilling: Machine-drill via holes using carbide bits. Thick copper boards need slower drill speeds and peck-drilling cycles to prevent bit wear and ensure hole quality.

7. Through-Hole Plating: Deposit copper into drilled vias via electroless or electrolytic plating. Thick copper requires thicker via barrels (≄1.5 mils) to withstand high current and thermal stress.

8. Solder Mask: Apply epoxy-based solder mask using screen printing or spray coating. Thick copper boards may need adjusted mask thickness to cover raised copper areas.

9. Surface Finish: Apply finishes like HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservative) for solderability and corrosion resistance.

10. Testing: Perform electrical continuity tests, thermal cycling, and impedance checks to validate performance under high-current and high-temperature conditions.

Welcome to contact us if you have any request for copper PCB board: sales@bestpcbs.com.

What Is A 1 oz Copper PCB?

A 1 oz copper PCB utilizes a copper layer thickness defined by the historical unit “ounce per square foot” (oz/ftÂČ), where 1 ounce of copper is uniformly spread over one square foot of surface area. This results in a physical thickness of approximately 35 micrometers (”m) or 0.0348 millimeters. This standardized measurement balances electrical conductivity, manufacturability, and cost-effectiveness for a wide range of electronic applications.

It serves as the fundamental benchmark for conductivity and current-carrying capacity in most printed circuit boards across consumer electronics, industrial controls, and communication devices. Designers carefully correlate trace widths with this 35”m copper thickness to ensure adequate current flow without excessive voltage drop or overheating. While thicker copper layers exist for high-power applications demanding greater ampacity or thermal dissipation, the 1 ounce copper specification remains prevalent due to its optimal performance in standard circuits and efficient fabrication processes.

What Is A 1 oz Copper PCB?

What Is the Thickness of 1 oz Copper PCB?

The thickness of a 1 oz copper PCB is defined by the industry-standard weight-to-area measurement. Specifically, 1 ounce (oz) of copper uniformly distributed over one square foot (ftÂČ) area results in a physical thickness of approximately ‌35 micrometers (”m)‌ or ‌0.035 millimeters (mm)‌. This equivalently translates to about ‌1.4 mils‌ (thousandths of an inch) in imperial units.

What Is the Thickness of 1 oz Copper PCB?

What Is the Height of 1 oz Copper PCB?

The height (thickness) of 1 oz copper on a printed circuit board (PCB) measures 35 micrometers (”m), equivalently 0.035 millimeters (mm) or 1.4 mils (thousandths of an inch). This standard thickness results from the industry practice where one ounce of copper is uniformly distributed over one square foot of surface area. The calculation accounts for copper density at approximately 8.92 g/cm³ to achieve consistent thickness values that ensure manufacturing reliability and electrical performance.

What Is the Current Capacity of 1 oz PCB?

The current-carrying capacity of 1 oz copper PCB traces depends on width and temperature rise. A standard 10mm (0.4″) wide 1 oz (35”m) trace can safely carry about 5A with a 10°C temperature rise, or up to 8A with a 20°C rise. For precise calculations, use the IPC-2152 standard or online PCB trace width calculators that account for copper thickness, ambient temperature, and desired temperature rise.

        Decent Quality Aluminum Circuit Board for Prototype

        What Is Aluminum Circuit Board?

        An aluminum circuit board, also called metal core PCB or MCPCB, uses aluminum as its base instead of traditional FR4. It improves heat management and structural durability, which is vital for LED lighting and power devices. Unlike regular boards, these handle high temperatures without deforming. That’s why many engineers choose aluminum PCBs during prototyping.

        What Is Aluminum Circuit Board?

        What Is the Type of Aluminium PCB Board for LED?

        For LED projects, the most common type is single-sided aluminum PCB. It’s compact and handles thermal loads well. But in high-power or RGB LED systems, double-sided or multilayer aluminum PCBs offer better performance. They reduce LED failure by improving heat flow. Best Technology supports custom layouts, even in tight spaces or dense LED arrangements.

        Which Is Better: Aluminum PCB vs FR4?

        Which is better: aluminum PCB vs FR4? Aluminum PCB beats FR4 in thermal performance. It draws heat away from sensitive parts, boosting LED lifespan and reducing risk. While FR4 costs less, it can’t manage heat well, especially in power circuits. In prototypes with high-current designs or compact layouts, aluminum wins. Plus, it supports better mechanical strength, cutting down failures during handling.

        How Is the Aluminium PCB Manufacturing Process?

        Making aluminum circuit boards involves steps like copper etching, dielectric lamination, and mechanical drilling. The copper layer must be etched with tight control. Some suppliers struggle here—especially above 3oz copper thickness. But Best Technology applies auto optical width checks and dynamic compensation algorithms. That keeps the line width deviation under ±0.02mm, even with 8oz copper. For heat bonding, vacuum lamination and real-time monitoring improve consistency, reducing delamination risks in LED arrays.

        How Is the Aluminum Circuit Board Price?

        Aluminum circuit board price varies with size, copper weight, layer count, and surface finish. Basic single-layer aluminum PCBs are cost-effective. But high-current designs with multiple layers cost more. Still, when you compare the longer LED lifespan, saved redesigns, and lower cooling costs, they provide better long-term value. Best Technology offers reasonable aluminum PCB prices, especially for small batches and prototypes.

        How Is the Aluminum Circuit Board Price?

        What Are the Advantages of Aluminum Printed Circuit Boards?

        They shine in thermal management. The metal core pulls heat away quickly, protecting components. They’re durable and resist cracking better than FR4. For LED lighting, aluminum PCBs keep junction temperatures in the safe zone. This extends light quality and life. They also reduce the need for heat sinks, cutting system cost and weight. Aluminum PCB boards are also RoHS compliant and recyclable, supporting green goals.

        Why Choose Best Technology as One of Your Reliable Aluminum Circuit Board Manufacturers?

        2. Complex Layout Support

        Some designs need tight layouts. We support 0.5oz – 10oz conductor thickness, 4/4mil line space, and 0.48mil PTH wall thickness for HDI. The max board dimension supports up to 610*1625mm, and the MCPCB layers support up to 10 layers. Our thermal mapping and 3D layout tools balance heat and layout density—great for power-dense applications.

        3. Controlled Drilling & Milling

        CNC defects slow down prototyping. With laser depth control and anti-vibration tools, we prevent burrs and hole deformation. That means more reliable testing and less rework.

        4. Strict Quality Assurance

        We follow ISO 9001, ISO 13485, IATF 16949, AS9100D, and IPC Class 3. All batches are traceable, RoHS-safe, and meet UL requirements. Heat cycle tests from -55°C to +150°C, AOI checks, and electrical tests ensure long-term reliability.

        Aluminum PCB for Round High Bay LED Lights | Best Technology

        July 15th, 2025

        What Is a Round High Bay LED Light?

        A round high bay LED light is a type of industrial lighting fixture used in buildings with high ceilings—usually more than 20 feet. These lights are designed in a circular or UFO-style shape to evenly distribute light over large areas. You’ll often find them in warehouses, gymnasiums, factories, airports, and retail stores. Compared to older metal halide or fluorescent systems, round high bay LED lights are more energy-efficient, last longer, and require less maintenance.

        Each fixture typically contains multiple high-power LEDs mounted on a metal-core PCB, surrounded by a reflector and protected by a lens. These components are arranged to direct intense, bright light downward to cover a wide area. The circular layout is easy to install, especially for ceilings where centralized lighting is needed.

        Aluminum PCB for Round High Bay LED Lights

        Do High Bay LED Lights Get Hot?

        Yes, high bay LED lights can get hot—especially after extended use. Although LEDs are more efficient than traditional lighting sources, they still generate heat during operation. The more powerful the light (for example, 100W, 150W, or 200W round high bay fixtures), the more heat it produces.

        Unlike incandescent or halogen lights, LEDs don’t emit heat through infrared radiation. Instead, their heat builds up internally around the chip and must be conducted away through the PCB and heat sink. If the heat isn’t managed properly, it can reduce the light’s efficiency, shorten the LED’s lifespan, and even cause failure. That’s why thermal management is crucial for high bay LED lights—and why aluminum PCBs are widely used in their construction.

        Why Use Aluminum PCB for High Bay LED Lights?

        Aluminum PCBs are preferred in round high bay LED lights because they offer excellent thermal conductivity. In high bay environments, LED chips are packed closely together on a board, creating a concentrated source of heat. Aluminum PCBs help move this heat away from the chip quickly, reducing the risk of overheating.

        Traditional fiberglass PCBs (like FR4) are not good at handling thermal loads. They trap heat near the components, which can lead to LED failure. In contrast, aluminum PCBs consist of a metal base layer, a dielectric insulation layer, and a copper circuit layer.

        Using aluminum PCBs in high bay LED lights also helps to maintain consistent brightness, reduce light degradation over time, and support longer operating lifespans—often 50,000 hours or more.

        Aluminum PCB for Round High Bay LED Lights

        Advantages of Using Aluminum PCB

        1. Aluminum PCBs rapidly transfer heat away from LED chips, so that they can reduce the temperature at the LED junction and maintains stable light output over time.

        2. High bay lights are often used in demanding environments like factories and warehouses. The base material of aluminum PCB is metal, so they can provide better structural stability and resistance to vibration and moisture.

        3. When LEDs operate at lower temperatures, their lumen output remains consistent for years with minimal degradation.

        4. Despite their strength, aluminum PCBs are relatively lightweight compared with copper core PCB. This can reduce the overall weight of the high bay fixture, make it easier to install and handle.

        5. Though aluminum PCBs cost more than standard FR4 boards, their durability, reliability, and low maintenance result in long-term savings—especially in industrial settings where lighting failures can be costly.

        1W vs 2W vs 3W Aluminum PCB: Which One Is Best?

        In aluminum PCBs used for round high bay LED lights, the terms 1W, 2W, and 3W refer to the thermal conductivity of the dielectric layer between the copper circuit and the aluminum base, not the power of the LEDs themselves.

        It’s measured in watts per meter-kelvin (W/m·K) and indicates how efficiently heat is transferred from the copper to the aluminum core. The main job of dielectric layer is to insulate electrically while conducting heat away from the LED components. Here’s how they compare:

        • 1W Aluminum PCB

        1W PCBs are used for low-power applications where heat is minimal. They’re suitable for small or decorative lights but not recommended for industrial high bay systems. The heat dissipation capacity is limited, and using them in high-power lights may cause overheating.

        • 2W Aluminum PCB

        2W PCBs offer better heat conductivity than 1W versions and are often used in mid-power LED lights, such as 50W to 100W systems. They provide a balance between performance and cost, and they work well in moderately demanding environments.

        • 3W Aluminum PCB

        3W PCBs are designed for high-performance LED lighting. They are ideal for 150W to 200W round high bay fixtures, where multiple high-output LEDs are densely packed. These boards handle more heat and offer higher durability under continuous operation.

        So, which one is best? For round high bay LED lights used in industrial or commercial buildings, 3W aluminum PCBs are usually the best option. They support powerful LEDs, provide excellent thermal control, and reduce the risk of system failure.

        Aluminum PCB for Round High Bay LED Lights

        Round High Bay LED Lights PCB Design Guide

        Designing a printed circuit board (PCB) for round high bay LED lights requires special attention to thermal management, electrical performance, mechanical stability, and spatial efficiency. These lights operate in high-ceiling environments and typically involve high power, which means the PCB must handle significant heat while maintaining long-term reliability.

        1. Shape and Form Factor

        Since the fixture is round, the PCB is typically designed in a circular shape to match the housing and ensure symmetrical light distribution. This helps maintain uniform brightness across the target area and improves heat spreading across the surface.

        To design the board:

        • Use radial symmetry when placing LED chips to maintain uniform light output.
        • Create concentric LED rings to balance thermal and optical performance.
        • Align mounting holes and cutouts with the housing’s mechanical features for secure fitting.

        2. Material Selection: Aluminum Core

        The aluminum substrate is the foundation of thermal performance. Choose high-quality aluminum cores with good thermal conductivity—typically in the range of 1.0 W/m·K to 3.0 W/m·K.

        Common material stack-up:

        • Top layer: Copper circuit (usually 1oz or 2oz)
        • Middle layer: Dielectric insulating layer (optimized for thermal transfer, usually 75–150ÎŒm thick)
        • Bottom layer: Aluminum base (typically 1.0–1.6mm thick)

        Noted: The thicker the base, the higher the dielectric layer value, the better the heat transfer, but also the heavier and costlier the board becomes.

        3. Copper Thickness and Trace Width

        For high-power LEDs, the copper thickness should be:

        • 1oz (35ÎŒm) minimum for moderate power (≀100W)
        • 2oz (70ÎŒm) or 3oz (105ÎŒm) for high-power designs (≄150W)

        Use wide copper traces to reduce resistive losses and avoid overheating. Calculate trace width based on expected current using IPC-2221 standards.

        4. Thermal Management Techniques

        Heat dissipation is critical in high bay LED lights. Key design methods include:

        • Use direct thermal path: Use thermally conductive vias or metal-core structures to transfer heat from LEDs to the aluminum base.
        • Thermal vias: For multilayer aluminum PCBs (if needed), add thermal vias below heat-generating components to improve vertical heat flow.

        5. LED and Component Placement

        Carefully plan the placement of LEDs, drivers, resistors, and protection components:

        • LEDs: Distribute evenly in radial or concentric patterns to ensure uniform illumination.
        • Driver ICs and capacitors: Place these in cooler areas away from dense LED zones to reduce thermal interaction.
        • Thermistors or temperature sensors: Add for real-time temperature monitoring and safety.

        Avoid placing heat-sensitive components directly beside high-heat sources.

        6. Electrical Isolation and Safety

        Since aluminum is conductive, electrical insulation is critical. The dielectric layer between the copper circuit and aluminum base must withstand at least 2–3kV isolation voltage. It is better to consult your PCB manufacturer to get a best solution.

        What Is a Motor Board and Why Do You Need a Motor Driver Board?

        July 15th, 2025

        A motor board is a key part of any system that controls electric motors. Whether you’re building a small robot, a smart curtain, or a DIY RC car, the motor board is the part that connects your brain (the microcontroller) to your muscle (the motor).

        You cannot connect a motor directly to an Arduino, Raspberry Pi, or other microcontroller because motors need more power than these boards can handle. That’s where a motor driver board comes in. It supplies power and manages direction, speed, and safety.

        In this guide, we’ll explore what a motor board is, the types available, how it works, and why it’s so important for any project with moving parts.

        What Is a Motor Board and Why Do You Need a Motor Driver Board?

        What Is a Motor Board?

        A motor board is a small printed circuit board (PCB) designed to control electric motors. It acts like a translator between your low-power controller and your high-power motor. You send simple signals to the board, and the board powers and controls the motor for you.

        Motor boards are often used in robotics, automation systems, and electric vehicles. They are essential when you want to move wheels, turn gears, lift arms, or rotate anything using a motor.

        They can work with different types of motors, such as:

        • DC motors
        • Stepper motors
        • Servo motors
        • Brushless DC motors (BLDC)

        Each motor type may require a different kind of motor board.

        What Does Motor Board Mean?

        The term motor board means a circuit board made specifically for motor control. It includes components like driver chips, power inputs, connectors, and sometimes sensors.

        In simple terms, it’s a smart power switch. You tell it what to do (via signals from a microcontroller), and it supplies the right amount of power to the motor.

        For example, when building a robot, the main board might handle logic, sensors, and communication. The motor board only deals with moving the wheels. That separation makes the system more reliable and easier to design.

        Types of Motor Board

        There are many types of motor boards, and each one is built to handle specific motors or motion requirements. Here are the most common:

        1. DC Motor Driver Boards

        These are used for basic motors that rotate in one direction or both. You can control speed and direction using PWM (pulse width modulation) and digital pins. A popular example is the L298N motor driver board, which can run two DC motors at once.

        2. Stepper Motor Boards

        Stepper motors move in fixed steps, not continuous rotation. These are great for projects that need precise movements, like 3D printers or CNC machines. Boards like the A4988 or DRV8825 are common choices. They control the step rate and direction.

        3. Servo Motor Boards

        Servos move to specific angles. They are used in robotic arms, RC cars, and camera gimbals. Servo boards control the angle through a PWM signal. Some boards allow you to connect many servos at once for large projects.

        4. Dual H-Bridge Motor Boards

        An H-Bridge lets current flow in both directions through a motor. This means your motor can spin forward or backward. A dual H-bridge board like the L298N or L293D can control two DC motors independently.

        5. Brushless DC Motor (BLDC) Boards

        BLDC motors are used in drones, electric skateboards, and industrial tools. They need more complex driver boards that handle three-phase power and feedback from position sensors. These boards often include FETs, controllers, and overcurrent protection.

        Why Do You Need a Motor Driver Board?

        6. Electric Motor Boards for Vehicles

        These high-power boards control large motors in e-bikes or scooters. They usually feature thermal sensors, regenerative braking, current limiters, and fault indicators. They are more robust than typical hobby motor boards.

        What Does a Motor Driver Board Do?

        A motor driver board takes control signals from a microcontroller and uses them to control the motor’s power. It does several important jobs:

        • Amplifies signals: Microcontrollers output low voltage. Motor driver boards boost these to match motor power requirements.
        • Controls direction: By switching current direction, the motor can spin forward or backward.
        • Adjusts speed: PWM signals let you change motor speed smoothly.
        • Protects components: Built-in diodes or protection chips guard against backflow current (back EMF), which can harm your controller.
        • Manages current: Some drivers limit current to prevent motor or circuit damage.

        So, the motor driver board is the part that makes motors usable with small electronics.

        What Is a Motor Board and Why Do You Need a Motor Driver Board?

        What Color Is a Motor Board Usually?

        Most motor boards are green, the standard color for PCBs. This green color comes from the solder mask, which protects the copper traces underneath.

        However, boards also come in:

        • Red – used by SparkFun and many other hobby suppliers
        • Blue – seen in some open-source projects
        • Black – popular for higher-end or custom boards
        • Yellow or White – rarely used but available

        The color doesn’t affect performance. It’s just for looks and branding. Pick based on function, not color.

        How to Make a Motor Board?

        If you want to build your own motor board, here are the basic steps:

        1. Choose Your Motor

        Decide if you’re using a DC, stepper, or servo motor. Each needs a different driver.

        2. Pick a Driver Chip

        Choose a suitable IC:

        • L298N for two DC motors
        • A4988 for stepper motors
        • TB6612FNG for better efficiency

        3. Design the Circuit

        Use PCB design software like: KiCad, EasyEDA, Eagle. Include connectors, capacitors, and resistors as needed. Add power input terminals and logic pin headers.

        4. Create the PCB

        You can:

        • Order from a PCB maker online like PCBway (lowest price but poor quality) or Best Technology (competitive price with higher quality and 5 years quality guarantee).
        • Etch it manually at home (not recommended for beginners)

        5. Assemble the Board

        Solder all components. Double-check the orientation of ICs, diodes, and power connections.

        6. Test It Safely

        Start with a small motor. Use a current-limited power supply. Test using an Arduino with simple code.

        Building your own board is a great learning project, but for complex systems, buying a tested module is safer and faster.

        How to Make a Motor Board?

        Why Do You Need a Motor Driver?

        Microcontrollers are smart, but they’re weak when it comes to power. Motors often need 6V–24V and 1A or more. An Arduino pin provides only 5V and about 20–40mA.

        If you connect a motor directly to the microcontroller, two things might happen:

        1. The microcontroller resets or freezes

        2. The motor doesn’t spin—or worse, the controller burns out

        A motor driver board solves this. It protects your control board while giving the motor what it needs.

        It also adds:

        • Precise control (change speed or reverse easily)
        • Electrical isolation in some cases
        • Protection features like thermal shutoff or current limiting

        So, every project with motors—big or small—should include a driver.

        Why Do You Need a Motor Driver?

        What Is the Use of a Motor Driver Board?

        A motor driver board is used in any system that requires motion. Here are some common uses:

        1. Robotics

        From mobile robots to robotic arms, motor drivers control wheels, joints, and actuators. You can run multiple motors and coordinate movement smoothly.

        2. Automation

        In smart homes and factories, motors open doors, close blinds, or move conveyor belts. Motor boards provide the control logic behind these actions.

        3. Drones and RC Vehicles

        Brushless motor driver boards keep drones stable and responsive. In RC cars, motor boards drive wheels, steering, or servo-based suspension.

        4. 3D Printers and CNC Machines

        These use stepper motor drivers to move the nozzle or cutter precisely. Each axis has its own board.

        5. Electric Bikes and Scooters

        High-current boards manage wheel motors, brakes, and regenerative systems.

        A motor board is more than just a piece of hardware—it’s the control center that makes electric motors useful in real projects. Without one, your motor can’t respond to speed or direction commands, and your controller may get damaged trying to power it directly.

        There are many types of motor boards, from basic DC motor drivers to advanced BLDC boards used in EVs. You can buy them off the shelf or design your own if you’re building a custom system. Whether you’re working on a robot, a drone, or a smart appliance, the motor driver board is a must-have. It turns signals into motion, safely and efficiently.

        FAQs

        1. Can I run a DC motor without a motor board?

        You can, but it’s risky. Motors draw more current than microcontrollers can handle. You could damage your board.

        2. What is the best motor driver board for beginners?

        The L298N is affordable, easy to use, and works with most Arduino projects.

        3. Can a motor board control more than one motor?

        Yes. Dual motor boards control two motors. Some advanced boards can control four or more.

        4. Are all motor boards compatible with all microcontrollers?

        Not always. Check the logic level (3.3V vs. 5V) and connection type. Most hobby boards are designed for Arduino compatibility.

        5. Is it safe to build your own motor board?

        Yes, with proper design and low-voltage testing. Always double-check your connections and power ratings.

                What Can You Do with Altium CircuitMaker?

                July 15th, 2025

                Altium CircuitMaker is a great choice for anyone getting started with PCB layout. It’s free, cloud-connected, and ideal for makers and small design teams. Many users look for a tool that’s easy to use but still powerful enough to handle complex tasks. CircuitMaker offers that balance while helping you avoid common roadblocks like high cost or outdated features.

                Best Technology is a PCB & PCBA manufacturer, providing services from PCB layout, DFM analysis, PCB prototype, fabrication to assembly. We have been in the PCB industry for 19 years. You can take the merit of our full experience from engineers for the viable EMS PCB manufacturing solutions. For inquiries or more info, email us at sales@bestpcbs.com.

                What Can You Do with Altium CircuitMaker?

                What is an Altium CircuitMaker?

                Altium CircuitMaker is a free PCB design software from Altium. It targets hobbyists, students, and startups who need a professional tool but don’t have the budget for premium software. Though it’s free, it uses the same engine as Altium Designer. That means your layout process is smooth and accurate. CircuitMaker supports both local project saving and cloud-based collaboration, allowing flexible access to your designs.

                What is an Altium CircuitMaker?

                Which Is Better: CircuitMaker vs KiCad?

                When choosing between CircuitMaker and KiCad, it depends on your needs. KiCad is open-source and highly customizable. It’s offline and doesn’t force cloud storage. But CircuitMaker comes with Altium’s engine, better routing tools, and a cleaner user interface. Collaboration is easier with CircuitMaker, especially with Altium 365. While KiCad is great for full control, CircuitMaker suits faster, shared workflows. If you prefer working in a cloud-based system, CircuitMaker is the stronger choice.

                Altium CircuitMaker vs Altium Designer: What Should You Choose?

                The main difference between Altium CircuitMaker and Altium Designer lies in the feature set. CircuitMaker is limited in some areas like simulation and advanced rule settings. Altium Designer, on the other hand, includes everything: 3D modeling, SPICE simulation, and full control over every design rule. If you’re working on commercial products, Designer is the better tool. However, CircuitMaker is a strong entry point. Plus, since both tools use similar workflows, upgrading later is easy. If you’re just exploring options, try CircuitMaker after your Altium download to test the interface before buying a license.

                Altium CircuitMaker vs Altium Designer: What Should You Choose?

                Can Students Use Altium CircuitMaker with an Altium Student License?

                Students can use CircuitMaker without a paid license. It’s part of Altium’s push to support education and learning. The software is free for non-commercial use. While Altium Designer needs a student license, CircuitMaker does not. That makes it a great way for students to get comfortable with PCB tools early on. For those aiming to move into professional work, CircuitMaker helps bridge the gap with a familiar interface and real-world design tools.

                What Are the Benefits of Using Altium CircuitMaker with Altium 365?

                Using Altium CircuitMaker with Altium 365 brings new levels of team collaboration. You can share your design with teammates in real time. Feedback is instant. You no longer need to send files over email or worry about version control. Your projects are backed up in the cloud and accessible from any device. This workflow reduces errors and saves time.

                What Are the Limitations of Altium CircuitMaker?

                Despite being powerful, Altium CircuitMaker limitations still matter in some cases. For one, it’s for non-commercial use only. Your projects must be public. There’s no way to use private storage in the free version. Also, it lacks simulation features, BOM export customizations, and flexible design rule checks. Finally, all designs are cloud-based, which may not fit all workflows. Still, for educational and hobby use, these limits are manageable. At Best Technology, we often help customers move designs from CircuitMaker to professional tools when scaling up.

                How to Get Started with Altium CircuitMaker Download?

                Getting started is simple. Visit Altium’s website and find the CircuitMaker download page. Sign in with a free account, then follow the installer instructions. Once installed, you’ll log into your workspace and start a new project. The UI feels familiar if you’ve used other Altium tools. Even if you’re new, CircuitMaker includes tips and templates to help you begin. If you ever outgrow it, migrating to Altium Designer is straightforward thanks to shared file structures.

                If you’re using Altium CircuitMaker for your printed circuit board layout, we can help take your design files and turn them into tested, assembled boards without delay.

                To sum up, Altium CircuitMaker gives you the tools to design PCBs without the learning curve or license cost of high-end software. It’s a solid platform to learn, experiment, and grow. With features powered by Altium and collaboration tools through Altium 365, it’s perfect for teams or classrooms.

                When it’s time to scale up, Best Technology can step in. We help bring your designs to production while solving the real issues of PCB material or PCBA component sourcing, cost, and quality. Whether you’re a project manager or PCB engineer, we make sure your design moves forward—quickly and reliably.
