With the development of technology, LED lights are more and more widely used. How can we custom LED PCB?
LED PCB is the core of LED lighting. The chip establishes electrical connection between LED and PCB and is equipped with heat sink to dissipate heat.
Metal core PCB, especially aluminum PCB, is favored by LED PCB manufacturers because of its good heat dissipation performance.
Usually, aluminum LED PCB has a thin layer of thermally conductive dielectric material, which has higher heat dissipation efficiency than traditional PCB.
Application of LED PCB Board
LED PCB light has a wide range of applications in different industries with its low cost and flexible design as well as excellent energy efficiency. It can be generally used in industries such as medical, computer, automobile and telecommunication.
Good heat dissipation performance
Lightweight design, easy to move
High efficiency and low power consumption
Dust and moisture proof
Mercury-free
No radio frequency
Medical industry: LED light PCB boards used for medical examinations are usually high-power and made of aluminum with good heat dissipation.
Computer industry: LED PCB lights are widely used in the computer industry because of its high mechanical thermal sensitivity of computers.
Automotive industry: Aluminum LED PCB can be used for brake lights, indicator lights and headlights of cars. This printed circuit board is durable and competitively priced.
Telecommunications: LED light circuit boards have been used in telecommunication equipment because of their excellent heat transfer capabilities.
Different types of LED circuit boards are created for different applications, and there are usually 5 types of LED PCBs.
They are flexible LED circuit board, rigid LED PCB, hybrid LED PCB, multi-layer LED PCB, single-layer LED PCB.

Custom Led Pcb Parameter Settings
When designing an LED PCB, there are several factors to consider, including the driver type, power supply, board size, and spacing between adjacent wires. There are two types of drivers: constant current (CC) and constant voltage (CV). Your choice depends on the type of LED you are using. The datasheet will indicate the correct settings. Once you know the correct driver type, you can start designing your LED lamp.
Custom Led PCB Component Layout
If you are considering designing an LED-powered product, it may be helpful to understand the components that make up a common PCB. These components include LEDs, circuits, and various other components. These components are usually in the shape of tiny "chips" or cylinders. As with any other circuit board, they should be placed on the board so as not to block the soldering surface. It will be behind the through-hole plated components.
PCBs with LEDs are usually made of multi-layer FR-4 substrates. Because LEDs generate a lot of heat, it is critical to design the board to accommodate this heat. In addition, LED PCB boards should allow for adequate space between metal, pads, and traces. Proper component tolerances can also reduce board errors. Finally, when embarking on LED PCB design, carefully consider the substrate, as the substrate will determine the heat conduction capabilities of the LED.
LED Board Wiring
LED board wiring is relatively simple, but you should pay attention to the leg length of each component in the LED PCB design. Typically, the cathode lead is the shortest and is connected to the same socket as the anode. The same is true for the resistor, which should be connected to the same socket as its anode. The same is true for the other wire, which should be red or black.
For LED board wiring, keep the following LED PCB design guidelines in mind.
customize led pcb
Before custom led pcb board design, select LED components based on your LED board design requirements.
Before you start wiring the LED board, plan out the LED PCB wiring layout and confirm its correctness.
Make sure that all LED components present in the LED PCB design are properly grounded on the board.
Use the appropriate wire gauge for each section of the LED PCB, depending on the current load.
Clamp any wires that cross other conductive paths to prevent interference or contact with any other components.
Shrink any exposed wire joints by applying heat as an additional measure to prevent interference or short circuits.
When we complete the LED PCB design, check the continuity between all points in the entire LED PCB circuit before applying power.
Always use an approved power supply when connecting external supply voltage to the LED PCB board in the LED PCB board design.
Before applying power, confirm that there are no short circuits, open circuits, reverse polarity, or wrong component placement.
Test the LEDs regularly to ensure optimal performance under different operating conditions. Correct LED PCB wiring in the LED PCB board design is essential for the operation of the LED.
