LED PCB Assembly – Hitech Circuits Co., Limited
What is the LED Circuit Board assembly?
Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.
We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

Number of layers for LED PCB
These layers are made up of aluminum and magnesium, but now have Copper base material and Ceramic base materials for LED PCB industry, we can meet it.
Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too.
Types of layers for LED PCB Assembly
Normally, the base layer is made using aluminum alloy metal.
This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat.
A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics.
It is highly heat resistant and protects the PCB against heat and mechanical stress.
The circuit layer, which is covered by a copper foil which can range from one to ten ounces.
LED Board type- single or in panel
Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time.
Some LED PCB Assembly is done on a single board while others are done on panel boards.
LED PCB Assembly Process
Roughly, the PCBA process can be divided into theses phases: soldering paste printing > SMT (surface mounted technology) > reflow soldering > AOI (automated optical inspection)> THT (through-hole technology) > wave soldering > touch-up and cleaning > IC-programming > FCT (functional tests) > aging testing.
Below we show you the process.
Step1. Summarizing Project Information
Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly:
Gerber
BOM
LED PCB specification
Quotation quantity
Once you have gathered these information, you can contact us and request for a quote.
Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be.
Step2. Discussion and details about custom LED PCB Assembly
Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities.
For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want.
Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them.
