LED PCB

LED PCB refers to led circuit board used in LED lighting; Common types include aluminum-based PCB, FR4 PCB, CEM1 and CEM3 PCB. With the popularity of LED lighting, the demand for led pcb board is increasing too. Many European and American customers began to set up SMD factories or LED lighting assembly factories in the local area, importing led circuit board from China, and then assembling them into lightings for sale. JHDPCB has been producing LED PCBs since 2009, and our production scale has reached the top 5 in China. Our led pcbs are exported to more than 100 countries.

What Is The Connection Of PCB And LED.

Printed circuit board is an important innovation in circuit technology. It uses less space and materials to achieve intricate circuits wiring. The same as other semiconductor products, Printed circuit board is the best way to electrically connect LED components. PCB welded with LED components is usually called “led PCB”. PCB technology affects our daily life in many spheres. With the rapid development of the printed circuit board industry, led PCB also came into being.

What Are the Types of LED PCB?

Aluminum PCB / MC PCB:
Aluminum pcb or mc pcb is the most widely used in LED lighting industry because of its excellent thermal conductivity. For high-power LED lighting, in order to prolong the service life of led chips or components, it is recommended to use aluminum substrate pcb. Especially the metal core pcb with high thermal conductivity. For example, aluminum pcb 1.5W/m.k, aluminum pcb 2.0W/m.k and aluminum pcb 3.0W/m.k, up to 10W/m.k or copper pcb.

Fr4 PCB:
Fr4 PCB is also used in LED lighting much, because FR-4 PCB has many advantages, such as light weight, good insulation performance, good dimensional stability, easy processing shape, etc. FR4 PCB can be considered for some low-power lighting or lighting with high insulation requirements. Click to view detailed FR4 material properties and related knowledge in PCB manufacturing.

Cem1 PCB:
Cem1 PCB is a semi-glass fiber material, which is often used as a substitute for FR4 PCB in the LED lamp industry. The difference is that cem1 is not resistant to high temperatures and is not suitable for reflow soldering above 240 ℃.

Cem3 PCB:
The same as cem1 PCB, cem3 PCB is made of semi-glass fiber, their material quality and functional characteristics are basically the same. The two can be used interchangeably. However, the material is usually not changed for PCB repeat order, which is conducive to maintaining the stability of PCB quality.

Flexible led PCB:
The flexible pcb is also commonly used for LED lighting. The flexible PCB for led has excellent bending resistance and can make different bends and radians with lamps or led strips. For more information on the relationship between FPCB and LED strips, please read the article “Why Is FPCB An Important Part Of LED Strips?“.

High-power lighting needs to use PCB with high thermal conductivity. JHDPCB can produce LED PCB up to 10W/m.k

What Should Pay Attention To When Selecting LED PCB?

1. Select the right material of the LED PCB. For example, aluminum pcb board for led is selected with heat dissipation demand, and cem1 PCB or cem3 PCB is selected for led pcb with cost saving demand.
2. Choose the appropriate led PCB thickness. The common LED PCB thickness is between 0.8mm and 3.0mm. The thicker the LED PCB, the better the PCB’s ability to carry led beads and components.
3. Select the right copper thickness. The greater the current of the lighting, the greater the copper thickness should be selected. The copper thickness of LED PCB is between 18um and 105um.
4. Select the LED PCB solder mask color, the led pcb solder mask colors include white, mat black and green. White solder mask can be divided into Super white, blue-white and milky white. Click to see more solder mask manufacturing processes.

The high reflectivity solder mask helps to improve the overall lumen of the lighting. The milky white ink selected by JHDPCB has a high reflectivity of 95% and does not turn yellow after reflow soldering.

5. Select the appropriate surface treatment. The common surface treatment of LED PCB includes OSP, Hal, lf-hasl and Immersion Gold. However, the cost of Immersion Gold is high, so led PCB rarely use it. For details, please refer to our BLOG about surface treatment and choose the suitable process for you.
6. Finally, for some special requirements, if it is an aluminum pcb, the thermal conductivity should be considered. If it needs to be used in humid environment, CTI value shall be considered.

If the use environment of LED Lighting is humid, consider choosing PCB with CTI>600. JHDPCB has produced several PCB cases with CTI600 for customers.

LED PCB Board Capability of JHDPCB.

When you’re looking for an led pcb manufacturer or solution provider, it’s best to choose a led pcb factories that can help you prevent the most common led light pcb board problems. Here at JHDPCB, we can:

For LED PCB design or inspection-

Although LED PCB design is relatively simple, the same standards used for other PCBs may not necessarily apply to led pcb board. LED components have special requirements for led pcb circuit design, such as requiring LED PCB to have better heat dissipation, we can help you improve the design or help you do DMF(pre-production inspection), to ensure that your PCB design is suitable for your LED application. For example, traces on a printed circuit board should be sufficiently spaced from the edge of the PCB to prevent short circuits. The spacing between the pads, the line width and the line spacing must meet the LED lighting test standards, and the minimum line spacing should be greater than 5MM, which can prevent arcing and so on.

LED PCB heat dissipation problem-

LED components, especially high-power leds, can generate excessive heat, and if this heat is not dissipated in time, it may cause circuit board failure and shorten the life of the leds. Therefore, you must have a complete set of solutions to solve the thermal problem. Choosing an aluminum pcb substrate with high thermal conductivity and using a heat sink for the lamp to make the contact area between the aluminum substrate and the heat sink as large as possible will help solve these heat dissipation problems.

LED PCB withstand voltage problem-

When designing an LED printed circuit board, the potential maximum voltage and PCB usage environment should be considered. Do not allow the LED PCB to withstand the instantaneous voltage rise caused by inrush current and lightning strikes. JHDPCB will provide you with suitable LED PCB raw materials according to the maximum limit voltage of your driver input and the use environment.

LED PCB manufacturing process is RoHS compliant-

Many products and industries require PCBs to comply with Restriction of Hazardous Substances (RoHS) standards. Materials restricted by this regulation include:

  • Polybrominated diphenyl ethers;
  • polybrominated biphenyls;
  • Hexavalent chromium;
  • Cadmium;
  • HG;
  • Lead;

JHDPCB ensures that the led pcb board we produce are RoHS compliant.

DFM inspection minimizes performance issues due to design flaws-

Some PCB design flaws may cause performance issues. Problems that arise may include:

  • Short circuit or open circuit;
  • Performance drop;
  • Withstand voltage drop;

JHDCPB provides you with free DFM inspections to ensure led pcb board manufacturability. If there is a problem with the led pcb design, we will contact you and correct it before production.
