What is a Ceramic Chip Antenna?

A ceramic chip antenna is a compact antenna made from ceramic materials that efficiently transmit and receive radio frequency (RF) signals. Unlike traditional antennas, these are small, robust, and ideal for space-constrained devices.

These antennas operate based on dielectric resonance, where the ceramic material enhances signal propagation. They are commonly used in wireless devices like GPS modules, IoT sensors, Bluetooth-enabled products, and Wi-Fi systems. Due to their small size and strong performance, they are a popular choice in modern electronics.

Features of Ceramic Chip Antennas

Ceramic chip antennas are widely used in wireless communication because of their small size, stable performance, and durability. Unlike traditional metal antennas, they integrate seamlessly into compact devices without sacrificing efficiency. So, what makes them special?

1. Reliable Performance in Any Environment

One of the biggest advantages of ceramic chip antennas is their frequency stability. They can work consistently across different conditions while won’t affect its performance, that’s why they always appear in applications that require high-precision communication, like GPS and industrial IoT devices.

2. Easy to Integrate into PCBs

Ceramic antennas can be directly placed on a circuit board without affecting the overall design. So, engineers can easier to develop sleek and compact electronic devices while keeping manufacturing simple.

3. Small Size and Lightweight

Ceramic chip antennas take up very little space and weigh much less than traditional metal antennas. That’s why they are commonly used in Bluetooth devices, smart wearables, and IoT sensors, where every millimeter matters.

4. Withstands High Temperatures

Some ceramic chip antennas are designed to handle extreme temperatures, even up to 200-300°C.

5. Built for Tough Conditions

These antennas are built to last. They are resistant to interference, lightning, water, and dust, that can withstand outdoor, underwater, and extreme weather applications. From deep-sea exploration to volcanic monitoring, they perform reliably.

6. Strong Signal with Low Power Usage

Even though they are small, ceramic chip antennas provide efficient signal transmission with minimal energy loss. They can help to maintain strong wireless connectivity while reducing power consumption, which is especially useful in battery-powered devices.

Ceramic Chip Antenna Types

Ceramic chip antennas come in different types based on their frequency range, application, and design. Each type serves a specific purpose, whether for Wi-Fi, Bluetooth, GPS, or IoT applications. Below are some of the most common ceramic chip antennas used today.

1. PCB Trace Antenna

A PCB trace antenna is a type of ceramic antenna that is directly etched onto the circuit board using copper traces. It is one of the most cost-effective options but has certain limitations in terms of signal efficiency.

Since these antennas rely on PCB layout design, factors like board thickness, dielectric constant, and trace width impact performance. They are often used in low-cost wireless modules but require careful tuning to function correctly.

2. 2.4GHz Ceramic Chip Antenna

This antenna operates at 2.4GHz, the standard frequency for Wi-Fi, Bluetooth, and Zigbee communications. It offers better performance compared to PCB antennas due to its optimized ceramic structure.

3. ESP32 Ceramic Chip Antenna

The ESP32 is a widely used microcontroller with built-in Wi-Fi and Bluetooth capabilities. Many ESP32-based devices use ceramic chip antennas to enhance wireless communication without increasing size. They can work well with the ESP32 Wi-Fi + Bluetooth module, ensuring stable connectivity in embedded systems. But it has a limitation that its performance can be influenced by nearby metal components, requiring careful PCB layout.

4. GPS Ceramic Chip Antenna

5. Multiband Ceramic Chip Antenna

This antenna is designed to support multiple frequency bands, allowing a single device to operate across different wireless communication standards. They are versatile but limited in expensive manufacturing cost compared to single-band antennas.

So, in a word, if you need a cost-effective and space-saving solution, a PCB trace antenna works well. For Wi-Fi and Bluetooth, a 2.4GHz ceramic chip antenna is ideal. If your project involves IoT and ESP32 modules, go with an ESP32 ceramic chip antenna. For navigation and tracking, a GPS ceramic antenna is the right choice. If you need multiple functions, a multiband ceramic chip antenna offers the most flexibility. The best ceramic chip antenna depends on your end-application.

Ceramic Antenna vs PCB Antenna

PCB antenna is most used in the market, both types have their own strengths and limitations. When selecting an antenna for your application, which is the best? Herein, Best Technology will breakdown their differences in detail:

1. Material and Construction

A ceramic antenna is made from high-quality dielectric ceramic material, it is usually a standalone component that can be soldered onto a PCB. In contrast, a PCB antenna is simply a copper trace printed on the PCB itself, using the board’s material as the dielectric. PCB antennas require precise layout design to function effectively and are directly integrated into the board’s circuitry.

2. Size and Space Efficiency

Ceramic antennas are compact and self-contained, since they do not rely on a large ground plane, they can be placed in confined areas without significant loss in performance. PCB antennas, however, require a larger surface area to achieve good performance, as their efficiency is heavily dependent on ground plane size. In very small devices, a PCB antenna may not be practical due to space constraints.

3. Manufacturing and Design Flexibility

A PCB antenna is cost-effective and easy to manufacture since it is created directly on the PCB during the etching process. This eliminates the need for additional components, reducing bill of materials (BOM) costs. However, PCB antennas require careful tuning and optimization, so its design and manufacturing process more complex.

4. Cost and Production Considerations

PCB antennas are generally cheaper to produce, as they are just part of the PCB layout and do not require separate assembly. However, the hidden cost comes in the form of design complexity, tuning, and potential performance issues. Ceramic antennas, while having a higher unit price, reduce design time and improve reliability, leading to lower costs in the long run for high-performance applications.

How Does a Ceramic Antenna Work?

‌The working principle of ceramic antenna PCB ‌ mainly includes two processes of transmitting and receiving. The ceramic antenna uses GPS satellite to realize navigation and positioning. The main task of the user’s receiver is to extract the pseudo-random noise code and data code in the satellite signal, so as to solve the navigation information of the receiver carrier such as position, speed and time (PVT). Here is a detailed explanation for each process:

Signal Transmission – The antenna converts electrical signals into electromagnetic waves.
Signal Reception – It captures incoming RF signals and converts them back into electrical signals.
Impedance Matching – A matching network ensures efficient energy transfer between the antenna and the circuit.
Ground Plane Interaction – A well-designed ground plane improves signal stability and efficiency.

Ceramic Chip Antenna Design Considerations

Designing a ceramic chip antenna involves several factors that influence performance. Here are the key considerations:

1. Antenna Placement on the PCB

Antennas should be positioned at the edge or corner of the PCB to maximize radiation efficiency. Nearby metal components, shielding, or large ICs should be avoided as they can cause signal interference.

2. Ground Plane Size and Layout

A larger ground plane improves antenna efficiency by acting as a signal reflector. The PCB material should match the antenna’s specifications to maintain frequency accuracy.

3. Antenna Matching and Impedance Tuning

Most ceramic antennas are designed for 50Ω impedance, but variations in PCB layout can affect this. A matching network, typically using capacitors and inductors, engineers often use Pi or T matching networks to fine-tune performance.

4. Clearance and Keep-Out Zones

There should be no copper traces, ground planes, or metal components too close to the antenna. Keeping the antenna away from batteries, shields, and enclosures.

5. Operating Frequency and Bandwidth Considerations

Each ceramic antenna is designed for a specific frequency, such as 2.4GHz for Wi-Fi/Bluetooth or 1.575GHz for GPS. Any change in PCB layout can shift the resonance frequency, requiring fine-tuning.

What is the Most Effective Ceramic Antenna Shape?

The shape of a ceramic antenna influences its performance. The most effective shapes include:

Rectangular: Common in chip antennas, offering a balance between size and performance.
Helical: Provides better bandwidth and efficiency in small spaces.
Patch: Ideal for GPS applications, offering strong directional signals.
Planar Inverted-F Antenna (PIFA): Compact and efficient, widely used in mobile devices.

What is a Flexible PCB for LED Strip?

A flexible PCB for LED strip is a thin, bendable circuit board that holds LED components. Unlike rigid boards, it allows easy installation on curved surfaces. These PCBs are made with flexible base materials, such as polyimide or PET (polyethylene terephthalate), to support LED lighting applications that require flexibility, lightweight construction, and compact form factors. Unlike traditional rigid PCBs, flexible LED strips can be bent, twisted, or curved to fit various surfaces without breaking, so they are always used in wearable devices.

Flexible PCB for LED Strip, LED PCB Strip Manufacturer

Structure of a Flexible PCB for LED Strip

A flexible LED PCB strip consists of multiple layers that work together to provide electrical conductivity, mechanical strength, and heat dissipation:

Base Material (Substrate): The most common base material is polyimide (PI) due to its excellent flexibility, high-temperature resistance (up to 400°C), and durability. PET is used in cost-sensitive applications but has lower heat resistance.
Copper Layer: The conductive traces are made from rolled annealed (RA) copper or electrodeposited (ED) copper, typically 18µm (0.5oz) to 70µm (2oz) thick, depending on current requirements.
Adhesive Layer: Some flexible PCBs use adhesive-based or adhesiveless constructions to bond layers. Adhesiveless designs provide better thermal and electrical performance.
Solder Mask & Protective Coating: A flexible solder mask, such as PSR-9000FX from Taiyo, prevents oxidation and ensures insulation. Some LED strips use silicone or epoxy coatings for additional protection against moisture and dust.

Types of LED PCB Strip

LED PCB strips are classified based on the base material used for the PCB, which affects flexibility, heat dissipation, and durability. The most common types include FR4, aluminum, flexible polyimide, and ceramic PCBs (though copper base material has very good thermal conductivity, its heavy weight limited its usage in led PCB strip design).

FR4 LED PCB Strip: FR4 is a fiberglass-reinforced epoxy laminate that offers mechanical strength and cost-effectiveness. It has a low thermal conductivity (~0.3W/m·K), so it always used into low-power LED strips that do not generate excessive heat. However, it lacks flexibility, limiting its use in curved or flexible applications.
Aluminum LED PCB Strip: Aluminum-backed PCBs are designed for high-power LED applications, where efficient heat dissipation is critical. With a thermal conductivity of 1.0–3.0W/m·K, they outperform FR4 in heat management, ensuring longer LED lifespan and stable performance. These strips are commonly used in outdoor lighting, automotive headlights, and industrial applications.
Flexible Polyimide LED PCB Strip: Polyimide-based PCBs provide superior flexibility, allowing LED strips to bend without breaking. These PCBs typically have a thickness of 25–50µm, they are ideal for wearable lighting, signage, and decorative applications. While they do not dissipate heat as efficiently as aluminum PCBs, adding thermal vias can improve heat transfer.
Ceramic LED PCB Strip: Ceramic PCBs, such as aluminum oxide (Al₂O₃) and aluminum nitride (AlN), are used for high-temperature LED applications. They have an exceptional thermal conductivity of up to 180W/m·K (AlN). Due to it is expensive and classified into a kind of high-end product, it is mostly used in aerospace applications, where extreme durability is required.

Advantages of LED PCB Strip

Space-saving design – Thin and flexible, can be used in tight spaces that rigid PCB can’t achieve.
Durability – Resistant to bending, vibrations, and mechanical stress.
Heat dissipation – Transfers heat efficiently, improving LED lifespan.
Energy efficiency – Supports low power consumption, reducing costs.
Lightweight – Reduces overall weight in applications like automotive and wearable tech.
Customizable – Allows different layouts, colors, and LED densities, various material base available.

LED PCB Strip Design Considerations

Designing an LED PCB strip requires careful consideration of electrical, thermal, mechanical, and environmental factors to ensure efficiency, durability, and reliability. Here Best Technology listing some must-have to smooth your design phase:

1. Power Distribution: Voltage drops can cause inconsistent brightness, especially in long LED strips. For every 1-meter length, a 12V LED strip can lose 0.5V to 1V due to resistance. To prevent this, using parallel power feeds and power injection every 2–5 meters helps maintain stable voltage and brightness.

2. Current Handling: The copper thickness directly affects the strip’s ability to handle current. A 1oz (35µm) copper layer can safely carry up to 1.5A per mm of trace width, while a 2oz (70µm) copper layer can handle about 2.4A per mm. Selecting the right copper weight reduces resistance and prevents overheating, especially for high-power LED strips drawing more than 3A per meter.

3. Voltage Selection: Choosing the correct voltage improves efficiency. A 5V LED strip is best for short lengths but has higher current draw, while 12V and 24V LED strips offer better efficiency and lower current demand. A 24V strip allows longer runs (up to 10m) without noticeable voltage drop, making it ideal for commercial installations.

4. Heat Dissipation: LEDs convert 20-40% of electrical energy into light, with the rest generating heat. Aluminum-backed PCBs can dissipate heat 3-5 times more efficiently than standard FR4, reducing the risk of LED failure. Thermal vias with 0.3-0.5mm hole diameter can also improve heat dissipation by transferring heat from LED pads to the copper layers below.

5. Material Selection: FR4 PCBs are commonly used but have low thermal conductivity (~0.3W/m·K), making them less effective for heat dissipation. Polyimide flexible PCBs are better for bendable applications but require additional thermal management. Aluminum PCBs provide superior thermal conductivity of 1.0-3.0W/m·K, making them ideal for high-power LED applications.

6. Bendability and Flexibility: Flexible LED strips should maintain a minimum bend radius of 10mm to avoid stress fractures. For extreme flexibility, a polyimide PCB with 50µm thickness can be used. Components should be placed at least 1.5mm away from bending zones to prevent mechanical stress and circuit damage.

FAQs of PCB Assembly

1. What is the difference between PCB and PCB assembly?

A PCB (Printed Circuit Board) is the bare board with copper traces, while a PCB Assembly (PCBA) includes all the necessary electronic components soldered onto the board, making it a fully functional unit ready for use.

2. What is the purpose of a pick and place drawing in the SMT process?

A pick and place drawing provides detailed guidance for automated SMT machines, specifying component placement, orientation, and reference designators on the PCB. It ensures accurate positioning (including polarity indicators for diodes and capacitors) and facilitates post-assembly inspection.

3. What are counterbores and countersinks?

Counterbore: A cylindrical recess with a flat bottom, designed to allow a screw head to sit flush with the PCB surface. Commonly used with flat-head screws to ensure secure mounting, such as for attaching heatsinks or connectors.
Countersink: A conical recess that matches the angle of a tapered screw head, such as self-tapping screws. Helps create a smooth, low-profile surface, often used when securing PCBs within enclosures.

The key difference is that counterbore provides a level surface by embedding the screw head within the material. Countersink features a tapered design that aligns the screw and evenly distributes stress.

4. How to distinguish the PTH & NPTH?

PTH is PLATING Through Hole, it has copper in the holes inside, which can be conductive. NPTH is Non PLATING Through Hole, which don’t have copper inside the holes. Through holes means through the top and bottom on the PCB, it could be PTH and NPTH.

What is a Dipole Antenna PCB?

A dipole antenna PCB is a printed circuit board-based antenna designed with two conductive elements that serve as radiating arms. The word “dipole” means “two poles,” which describes the two symmetrical elements that make up the antenna. The length of these elements is typically half the wavelength of the frequency it operates on, which is why it is often called a half-wave dipole antenna.

This type of antenna is widely used in RF applications due to its simple construction, ease of manufacturing, and effective radiation properties. A dipole antenna PCB is commonly found in wireless communication systems, radio transmitters, satellite communication, and IoT devices. The radiation pattern of a dipole antenna is omnidirectional, making it ideal for applications that require uniform signal coverage.

Dipole Antenna PCB Design, Dipole Antenna PCB Manufacturer

Dipole PCB Antenna Design

Same as others antenna PCBs, designing a dipole PCB antenna requires careful consideration of factors such as frequency, impedance, substrate material, and radiation efficiency. The key aspects of designing a dipole PCB antenna include:

1. Determining the Antenna Length

The total length of a half-wave dipole antenna is calculated using the formula:

Where:

L = Length of the dipole antenna
λ = Wavelength of the signal
c = Speed of light (3 × 10^8 m/s)
f = Operating frequency

For example, for a 2.4 GHz Wi-Fi application, the length of a half-wave dipole antenna would be approximately 62.5 mm.

2. Choosing the Substrate Material

The choice of PCB substrate material affects the antenna’s efficiency and performance. The most common substrates used in dipole antenna PCB design include:

FR-4: Low-cost but has higher dielectric loss, suitable for general applications.
Rogers RO4000 Series: Low-loss, high-performance material for RF applications.
PTFE (Teflon): Ideal for high-frequency applications due to its low dielectric constant.

3. Impedance Matching

A standard dipole antenna has an impedance of 73 ohms in free space. To maximize power transfer, the impedance of the antenna must be matched with the feedline and transmitter, typically using a 50-ohm transmission line. This can be achieved through matching networks or baluns (balanced-to-unbalanced transformers).

4. Feed Mechanism

A dipole PCB antenna can be fed using:
Coaxial Feed: A direct connection to a 50-ohm coaxial cable.
Microstrip Feed: Uses a microstrip transmission line on the PCB for integration with circuits.
Balun Feed: Improves performance by converting an unbalanced signal into a balanced one.

Working Principle of Dipole Antenna PCB

A dipole antenna PCB operates based on the principle of electromagnetic radiation. It typically consists of two symmetrical conductive elements, arranged in a straight or semicircular configuration, which function as the transmitting and receiving elements. These two conductor arms are fed at the center, forming a half-wavelength antenna. The current distribution on the dipole antenna resembles that of an open transmission line, with current nodes appearing at both ends.

When an alternating current (AC) signal is applied at the feed point, the current oscillates along the dipole arms, generating an electric field. This interaction with the surrounding environment results in the propagation of electromagnetic waves. The efficiency of radiation depends on the length and shape of the conductors. Typically, a dipole antenna is designed with a length of 1/2 or 1/4 of the wavelength of the intended signal to maximize radiation performance. The working process shows as below:

In PCB design, placing a ground layer beneath the antenna can create a mirror effect, enhancing its performance. Additionally, careful PCB layout adjustments and ground layer configurations can optimize the antenna’s radiation efficiency and directivity, improving overall signal strength and stability.

Dipole Antenna PCB Advantages

Simple structure and easy to manufacture: The dipole antenna consists of two conductors of equal length, with a simple structure, easy to manufacture and maintain, and low cost.
Omnidirectional radiation: Dipole antenna can form a strong radiation field in two opposite directions, with omnidirectional radiation characteristics, suitable for applications that require uniform coverage of the surrounding environment, such as Wi-Fi hotspots or mobile base stations.
Standard impedance matching: It can easily achieve standard impedance matching of 50Ω or 75Ω, simplifying the connection with other RF components.
Good radiation pattern: The radiation pattern of the dipole antenna is relatively uniform in the horizontal direction and symmetrical in the vertical direction, which is suitable for some communication systems that require balanced feeding.
Higher gain: The gain of the dipole antenna is generally higher than that of the monopole antenna, especially in the vertical direction, which is more symmetrical and can provide a more uniform radiation field.
Wide Frequency Range: Can be optimized for different frequency bands.
Scalability: Can be designed for small devices like IoT sensors or large-scale communication systems.

Dipole Antenna Radiation Pattern

The radiation pattern of a dipole antenna is typically omnidirectional in the H-plane (horizontal plane), meaning it radiates energy uniformly in all directions. However, in the E-plane (vertical plane), it exhibits a figure-eight pattern, with maximum radiation perpendicular to the dipole elements. It always shows as below:

This characteristic makes dipole antennas ideal for applications requiring uniform signal distribution around the antenna’s axis.

Types of Dipole Antennas

1. Half-Wave Dipole Antenna: The most common type, where the total length is half the wavelength.

2. Folded Dipole Antenna: Features an additional conductor for higher bandwidth and impedance matching.

3. Short Dipole Antenna: Uses a shorter length but requires additional tuning for better efficiency.

4. Multi-Band Dipole Antenna: Designed for multiple frequency bands, useful in telecommunications and radar applications.

Applications of Dipole PCB Antenna

Wireless Communication: Wi-Fi, Bluetooth, and RFID systems.
IoT Devices: Smart home automation, industrial sensors, and medical wearables.
Broadcasting: AM/FM radio and television transmission.
Aerospace and Defense: Satellite communication, radar systems, and UAVs.
Automotive: Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication.

Unlike through-hole LEDs, SMD LEDs are mounted directly onto the PCB surface, enhancing efficiency and reducing assembly costs.

SMD LED PCB Design Software

Here are common SMD LED PCB design software:

‌Altium Designer-Offers comprehensive PCB design tools with 3D visualization.

KiCad: A free, open-source option for designing SMD LED PCBs.

EAGLE: User friendly and widely used in hobbyist and professional projects.

Cadence Allegro: Suitable for High-speed signal design field

SMD LED PCB Design Layout

The design layout of SMD LED PCBs mainly includes the following aspects:

Heat dissipation priority‌: copper is laid in the concentrated area of LED for heat dissipation, away from high-temperature components to avoid heat accumulation.
‌Wire optimization‌: the power line is short and wide to reduce impedance; the signal line and the power line are layered or spaced to prevent interference.
‌Uniform arrangement‌: the LED spacing is consistent, avoiding obstructions to ensure that the light-emitting surface faces the same direction.
‌Pad matching‌: the pad is designed according to the package size to avoid cold soldering; sufficient soldering spacing is reserved.
‌Polarity identification‌: clearly mark the positive and negative poles of the LED to avoid reverse patch; leave debugging marks on the board.

How To Design SMD LED PCB Board?

1. Parameter confirmation and selection ‌

Single LED operating voltage (such as 3V), current (20mA) and maximum power consumption (power = voltage × current).

Series/parallel configuration: series voltage superposition (total voltage = single voltage × quantity), parallel connection requires current equalization design.

Materials For general scenario‌: FR4 board (cost-effective, temperature resistance 130℃).

Materials For high power scenario‌: Aluminum substrate (thermal conductivity ≥2.0W/m·K, temperature resistance 150℃).

‌2. Layout design‌

‌Similar LED spacing‌ rule: ≥0.3mm (to prevent solder bridging).

‌Dissimilar device spacing‌ rule: calculated according to the formula ‌0.13×height difference (mm)+0.3mm‌ (such as LED height 1mm, resistor height 0.5mm, spacing = 0.13×0.5+0.3≈0.365mm).

All LEDs have the same long axis direction and are perpendicular to the reflow soldering direction (to prevent hot air from causing deviation).

The distance between the component and the edge of the PCB is ≥3mm. If it cannot be avoided.

V-Cut board division‌: Cut after extending the board edge, and wiring is prohibited at the cut.

‌Stamp hole board division‌: Separated by a 0.8mm diameter hole array, the hole center is ≥1.5mm from the board edge

‌3. Routing and power design‌

‌Line width calculation‌: Under 1oz copper thickness, line width (mil) = current (A) ÷ 0.024 (such as 1A current requires ≥42mil).

‌Copper plating stiffener: The LED negative pad is connected to a large area of copper plating (to reduce impedance and assist heat dissipation).

Filter capacitor layout‌: Each LED is connected in parallel with a 0.1μF ceramic capacitor (mounting distance ≤5mm).

Add 10μF~100μF electrolytic capacitors to the power inlet (to suppress low-frequency ripple).

‌Ground plane division‌: Single-point connection between digital ground and power ground to avoid noise coupling.

‌4. Thermal management design‌

Heat dissipation hole array‌: 0.3~0.5mm diameter through holes (1~2mm spacing) are drilled directly below the high-power LED, and the inner wall of the hole is metallized (to enhance thermal conductivity).

Copper foil area expansion‌: The copper area under the LED is ≥ 3 times the pad area (the aluminum substrate can be omitted).

The distance between LED and heating components such as driver IC and MOS tube is ≥ 5mm.

Avoid arranging electrolytic capacitors in high-temperature areas.

‌5. Design for manufacturability (DFM)‌

‌Pad design‌: The pad size is 0.2mm larger than the LED pin (e.g. LED pin is 1.6×0.8mm, and the pad design is 1.8×1.0mm).

The solder mask opening is 0.05~0.1mm wider than the pad (to prevent the solder mask from covering the pad).

Polarity mark‌: Add a “+” symbol or silk screen frame next to the LED pad (to prevent reverse connection).

Mark point: a solid copper point with a diameter of 1mm is arranged diagonally, and there is no component within 3mm around it. ‌

‌6. Test and debugging reservation‌

Reserve a 30mil diameter circular test point for each LED string circuit (connect to the positive pole of the power supply, ground and dimming signal).

The test point spacing is ≥2mm to avoid probe short circuit.

Reserve ≥1.5mm channels in dense LED arrays to facilitate hot air gun rework.

7. Design verification and simulation‌

‌Thermal simulation‌: Use ANSYS Icepak or similar tools to verify the high temperature area (the temperature rise of the aluminum substrate should be ≤30℃).

‌Power integrity simulation‌: Check the power ripple through Sigrity or HyperLynx (target ≤5% rated voltage).

‌DRC inspection‌: Focus on checking line spacing (≥0.2mm), aperture (≥0.3mm), and pad and through-hole avoidance (≥0.15mm).

‌8. Production file output‌

‌Gerber file‌: Contains circuit layer, solder mask layer, silk screen layer, and drilling file (aperture tolerance ±0.05mm).

Process marking‌: Clearly specify the solder mask color (white is preferred), surface treatment (immersion gold/OSP), and whether the aluminum substrate needs an insulation layer.

Lastly, you can move the production file to the make a SMD LED PCB board prototype.

What Are SMD LED PCB Board Design Rules?

Minimum spacing rule: When SMD layout is in progress, ensuring a certain spacing between components can reduce the probability of problems such as cold soldering, bridging, and shadow effects during welding.

PCB edge requirements: SMD components should not be laid out within 3mm from the two sides of the SMD PCB. This is because the guide groove of the placement machine requires that no components are allowed within 3 to 5mm of the PCB board edge. If this size cannot be guaranteed, consider using V-grooves or stamp holes to lengthen the board, and then remove the excess board after welding.

Arrangement direction: The arrangement direction of the same components should be as consistent as possible, and a test point with a diameter of 30mil must be left on the same gold track. In addition, the arrangement direction of CHIP, SOT, and SOIC components should be perpendicular to the tinning direction as much as possible to avoid shadow effects.

Shadow effect: When wave soldering is used, components with large height differences should not be arranged close together to prevent the shadow effect of high components from affecting the soldering of low components.

Test point requirements: When a right-angle (vertical) arrangement is required, sufficient tinning space must be reserved. The distance of this space should be 0.635mm.

SMD LED PCB Board Design Rules

FAQ of SMD LED PCB Board Design

1. ‌Improper pad design leads to welding defects‌

Use “water drop” routing transition to avoid right-angle connection of pads.

Symmetrically design the pad size to ensure balanced heat capacity on both sides.

2. ‌Insufficient heat dissipation leads to shortened LED life‌

Lay a sufficient area of heat dissipation copper foil (≥50mm²/W) under the LED and add heat dissipation through holes.

Aluminum substrate or metal core PCB is preferred for high-power scenarios.

3. ‌Uneven current distribution of parallel LEDs‌

Use star topology wiring to ensure that the length and impedance of each parallel branch are consistent.

Use constant current driver chip instead of traditional resistor current limiting solution.

4. ‌Process problems caused by overly dense component layout‌

Ensure that the LED spacing is ≥0.5mm and is more than 3mm away from the board edge.

During wave soldering, adjust the LED arrangement direction perpendicular to the tinning direction, and use a stepped steel mesh to control the amount of solder paste.

5. ‌Polarity marking error or silk screen blocking the pad‌

Clearly mark the LED polarity (such as the “+” symbol), and keep the silk screen away from the edge of the pad by ≥0.2mm.

During design verification, check whether the solder mask opening fully exposes the pad.

To sum up, the above is about SMD LED PCB design and how to select a good PCB supplier. If you have any other questions about designing SMD LED PCB, please leave a message below our blog. Looking forward to hearing from you soon!
