What is LED PCB?

Just as its name implies, LED PCBs are specialized circuit boards designed to power and support LED (Light Emitting Diode) lights. These PCBs must manage heat efficiently and distribute power effectively to handle the electrical load and heat generated by LEDs. They provide the essential platform for mounting LEDs and connecting them to other electronic components. LED PCBs are used in a wide variety of applications, ranging from basic light fixtures to sophisticated lighting systems in automotive, signage, and consumer electronics.

Typically, LED PCBs are made from materials with high thermal conductivity, such as aluminum or copper, to effectively manage heat. The design of these boards varies depending on the type of LED chips, such as surface-mount (SMD) LED or through-hole. LED PCBs also come in various forms, including flexible, rigid, and semi-flexible options, each tailored to specific lighting applications. Regardless of the type, careful attention to the LED PCB design is essential to achieve optimal performance and efficiency.

LED PCB Design Basics

Actually, the basics of a LED PCB design is a deep understanding and practice of both electrical and thermal engineering principles. LED circuit boards differ from standard PCBs because they must support higher currents and dissipate more heat. Therefore, careful planning is required in selecting materials, components, and layout strategies to ensure long-term reliability and efficiency.

At its core, LED PCB design focuses on three main factors:

Thermal Management: LED devices generate heat, which can damage the components if not managed correctly.
Current Distribution: The PCB must handle the specific current requirements of each LED.
Power Design: Since LEDs operate at specific voltages and currents, the power supply must be designed to match these needs.

5 Commonly Used LED PCB Design Software

How to Design a LED Circuit Board? – Step by Step

A good LED circuit board is based on a good LED PCB design. When you have a clear ideal and thought about your LED PCB, then you can start designing your PCB. Same as normal FR4 PCB, the LED PCB design starts from schematic drawing – layout – trace wiring – power integrity checking.

1. LED PCB Schematic Diagram Design

This diagram serves as the foundation for the PCB design, so any errors at this stage can lead to problems in the final board. Using a reliable schematic diagram tool to draw your circuit accurately and efficiently. Additionally, avoid overly complex circuits with multiple connections in a single diagram. Keeping the schematic clear and simple will make troubleshooting easier and ensure the design process progresses without issues.

2. LED PCB Layout

Once the schematic is finalized, the next step is the PCB layout. This involves placing the components and routing the traces that will carry the electrical signals to power the LEDs. This stage directly impacts the PCB’s performance, so precise planning and routing are essential. During the pcb layout, remember these tips:

High-power LEDs should be placed in areas with good airflow or close to heat sinks. It’s also important to keep resistors and power supply components away from heat-sensitive parts.
To ensure that the traces can handle the required current without overheating, you need to calculate the trace width. Tools like IPC-2221 or use our Online PCB Trace Width Calculators can help determine the appropriate width based on the current and copper thickness used in the PCB. For example, a 1oz copper PCB might need a trace width of 2mm to carry a 2A current safely.
Using separate power and ground planes to avoid voltage drops and noise. Power planes provide a low-resistance path for high-current traces, while ground planes help with signal integrity and reduce noise.
Thermal vias are often used to transfer heat from the LED to the PCB’s back layers or heat sinks. For high-power LEDs, these vias must be carefully placed to ensure that heat is efficiently dissipated.

3. LED PCB Wiring

Wiring refers to the creation of the electrical traces that connect the components on the PCB. Compared with FR4 PCB, wiring an LED circuit board is generally straightforward, but attention to detail is essential, particularly when it comes to the lead lengths of each component in the LED PCB design. Typically, the cathode lead is the shortest and connects to the same socket as the anode. Similarly, the resistor should be connected to the anode’s socket, and the other wire, often red or black, should follow the same principle.

Here are some important LED PCB design guidelines for wiring the LED circuit board:

Component Selection: Before starting the design, choose the LED components based on the specific requirements of your LED circuit board.
Plan the Wiring Layout: Carefully plan your LED PCB wiring layout and double-check its accuracy before proceeding with the wiring process.
Via and Trace Optimization: Minimize the use of vias, as they can introduce resistance and inductance. If vias are necessary, ensure they are appropriately sized and placed to handle the current.
Proper Grounding: Ensure that all LED components in the PCB design are correctly grounded to the circuit board.
Wire Gauge Selection: Use the appropriate wire gauge for each section of the LED PCB, depending on the current load in each path.
Prevent Interference: If any wire leads cross over other conductive paths, clamp them securely to prevent interference or accidental contact with other components.
Heat Shrinking: Apply heat shrink tubing to exposed wire junctions to protect against interference and reduce the risk of short circuits.
Signal Routing: Ensure that signal traces (such as PWM signals in RGB LED designs) are routed separately from power traces to prevent interference and maintain signal integrity.
Continuity Check: Before powering up your LED PCB, check for continuity throughout the circuit to ensure everything is connected properly.
Power Source: Always use an approved power supply when connecting external voltage to the LED PCB.
Final Check: Before applying power, make sure there are no short circuits, open circuits, reverse polarity issues, or incorrect component placements.
Test the LEDs: Regularly test the LEDs to ensure optimal performance under various operating conditions.

4. LED PCB Power Design and Analyzing

LED PCBs often require specific power designs to prevent overloading and ensure efficient energy consumption. You must consider the input voltage and how power will be distributed across the board. Proper power analysis ensures that the PCB operates within its designed power specifications.

5. LED PCB Signal Integrity Analysis

Signal integrity is an essential aspect of LED PCB design, particularly for high-speed or high-frequency LED applications. Ensuring that signals are not distorted during transmission will improve the overall performance and efficiency of the LED circuit. This phase involves simulating the behavior of the circuit to ensure it performs optimally under various conditions.

Simulate circuit behavior: Use specialized tools to simulate how the circuit will behave under different loads and environmental conditions.
Ensure minimal noise: Check for potential interference or noise in the circuit that could affect LED performance.

If you are interested in our LED metal core PCB manufacturing process, then the below video will show you all the steps in detailed.

LED Circuit Board Design Considerations

When designing an LED circuit board, several factors must be considered to optimize performance and reliability:

1. Outline Shape

LED PCBs come in various shapes, such as round, rectangular, or custom forms, depending on the final application. For example, LED strip PCBs are often flexible and come in long, narrow shapes, while LED array PCBs may need to accommodate multiple LEDs in a compact rectangular form.

2. Thermal Management

Effective thermal management is one of the most critical considerations when designing an LED PCB. LEDs generate heat during operation, and without proper heat dissipation, performance can degrade quickly, leading to shorter lifespan and possible failure. Aluminum PCBs are often used in LED designs due to their excellent thermal conductivity. Alternatively, copper-clad PCBs may be chosen for high-power applications to ensure that heat is efficiently transferred away from the LEDs.

3. Current Control

Each LED needs a current-limiting resistor to avoid excessive current that could damage the LED. In high-power LED applications, constant current drivers are often used to regulate the current supply.

4. Component Placement

Components should be arranged to minimize heat buildup, reduce interference, and maintain a clean signal path.

LED Positioning: Place high-power LEDs in areas with better airflow or near heat sinks. Ensuring adequate space around each LED can help manage heat more effectively.
Resistor and Capacitor Placement: Resistors and capacitors should be placed near the LEDs to minimize the impact of parasitic inductance or resistance. Proper placement also improves the overall efficiency of the circuit and minimizes signal loss.

5. Layout Optimization

The layout takes into account signal integrity and power integrity. In the layout, you need to follow the following principles:

Power and signal lines should be as wide as possible to reduce resistance and inductance.
The length of the power and signal lines should be as short as possible to reduce signal delay and noise.
Sensitive signal lines should be kept away from noise sources, such as motors, switches, etc.
The arrangement of power and signal lines should take into account the issue of electromagnetic interference (EMI).

FAQs

Q1: Are the via’s important for the thermal conduction?

From the via’s perspective, the via can be helpful in thermal conduction. At the same time, it is not that more heat dissipation through holes is better. The design of Via needs to be followed the minimax distance between holes. From the metal core material, the copper material is better than aluminum core in same situation. And sinkpad copper core PCB is better than copper core PCB. Because the convexity pad will be helpful in thermal conductivity. From the dielectric film, the 3W material is best. 2W material is better than 1W material. From the design of metal core PCB, the larger the area of solder mask opening means the larger the exposed copper surface outside, and the better the heat dissipation effect.

Q2: Does the dielectric in MCPCB cause problems at high temperatures?

The dielectric in MCPCB will cause problems at high temperatures, and the dielectric layer of MCPCB is the bottleneck of high temperature, because the Tg value of the layer is only 130℃.

Q3: What is the thickness of the thermal conductivity?

0.8W/m.k，Thickness=50-75um

1.0W/m.k，Thickness=75-100um；

1.5W/m.k，Thickness=100um

2.0W/m.k，Thickness=100-125um；

3.0W/m.k，Thickness=125-200um

For the breakdown, it is bigger when the line space is wider and the dielectric layer is thicker. Normally, the copper thickness is 10Z and 2OZ and surface finishing is HASL(LF), ENIG and OSP.

Q4: Can the aluminum be made as the base of sinkpad MCPCB?

Actually, the sinkpad can only use copper as the base. Because the SinkPad will etch the copper base into convex platform with Copper Etching Solution, then hollow out the Double Layer FR4 PCB, and do lamination with the convex platform. However, regarding of current technical conditions, since aluminum or aluminum alloy cannot directly react with acid, the reaction process is too complex and difficult to control, which will increase the difficulty of etching the LED pad platform. Considering the scrap rate, the process of etching LED pad platform with aluminum is more complex and the overall cost is higher.

Q5: It is possible dielectric + top metal layer to be >500um for wire bonding?

The dielectric layer and metal layer don’t affect the wire bonding, it depend on ENEPIG thickness, we do a lot of this kind of boards for our customers, as long as the do it with 3u”, then it is very good for wire bonding. If you insist on needing dielectric + top metal layer to be >500um, then the copper thickness need to be 10 OZ(350um), the price will be very high.

Software Tool for LED PCB Board Design

What Is the Best Practice for LED PCB Board Design Layout?

LED PCB Board Design Layout best practices include the following aspects:

‌Design optimization‌: During the design phase, DFM (design for manufacturability) checks are required to avoid concentrated distribution of high-heat generating components and to design heat dissipation channels reasonably. Ensure that pad size, line width and line spacing meet process capabilities.

Layout principles‌: Layout designers usually use schematics as a guide for placing components on the board to ensure optimal network connectivity between parts. Fixed-position parts such as connectors and switches should be placed first, and processors and memory components should be placed close to their connectors for optimal routing.

‌Signal routing tips‌: Add a common ground layer under the signal routing to minimize the impedance between ground points. Add vias in the grid to avoid hot spots, and use 135° routing bends when routing high-speed signals to reduce characteristic impedance changes and signal loss of transmission lines. Increase signal spacing outside the bottleneck area to avoid crosstalk, use daisy chains to maintain signal integrity, and maintain a constant distance when laying out differential pairs to achieve the specified differential impedance.

‌Power supply layout‌: The power supply should be placed near the load to prevent long traces from affecting power supply accuracy and dynamic load response. In multi-layer PCB design, a ground or DC voltage layer should be added between the high current layer and the sensitive small signal layer as a shielding layer to reduce interference.

What Is the Basic Rule of LED PCB Board Design?

The basic rules of LED PCB Board Design is mainly about the following aspects:

Control trace length: In design, it is advisable to control the trace length as much as possible, especially for important signal lines such as clock signals. The oscillator should be placed very close to the device to reduce unnecessary interference.

Control trace width and spacing: To reduce crosstalk between lines, ensure that the line spacing is sufficient. When the center-to-center distance of lines is no less than three times the width of the lines, 70% of the electric field can remain unperturbed from each other, known as the 3W rule.

Avoid sharp corners and right angles: In PCB design, avoid creating sharp corners and right angles, as they can produce unnecessary radiation and affect process performance. All line-to-line angles should be ≥135°.

Avoid self-looping traces: During design, pay attention to whether signal lines form self-loops between different layers, especially when routing on multilayer boards. Self-loops can cause radiated interference.

Avoid ‘antenna effect’: Generally, do not allow one end of a trace to be suspended to avoid the ‘antenna effect’, which reduces unnecessary interference radiation and reception.

Crosstalk control: Crosstalk refers to the mutual interference caused by long parallel traces between different networks. The main measures to overcome crosstalk are to increase the spacing between parallel traces, follow the 3W rule; insert grounded isolation lines between parallel lines; and reduce the distance between the wiring layer and the ground plane.

Ground loop rule: The area enclosed by the signal line and its return path should be as small as possible. The smaller the loop area, the less external radiation there is, and the less interference from the outside world.
