Single Layer PCB vs. Dual Layer PCB in Automotive LED Front Lights Bulbs

In typically, FR4, Aluminum PCB as well as Copper PCB all could be made into solitary layer PCB or double layer PCB

Solitary Layer PCB
Single layer PCB is the most frequently utilized, because it is simple to layout and also technique. This PCB covered a carrying out product on the one side of the board. Single layer PCB with an excellent heat dissipation, each chip dissipates warmth on one PCB, the LED headlight can be in a high lumen. Yet the size of 2 chip of 2 single layer PCB is as well large that mores than 3mm. Limited by the width, it could not simulate the halogen bulb tungsten cable, the beam is unclear with a dark area.

Double Layer PCB.
This PCB covered 2 performing product on the both side of the board. It supplies a more detailed distance between both side of the chips, which is similar to the thickness of halogen light bulb tungsten cable. For this outcome, it mimics the halogen bulb light-emitting types, the beam is a lot more much better. However, the both side of chips dissipate warm on one PCB, the heat can not be too high, so it limits the lumen for LED front lights.

It is not count on the location of PCB regarding the PCB warmth dissipation trouble. Thermal Management technology is one more core component of PCB application. In the following article, I will review thermal management Printed Circuit Board (PCB) technology, especially SINKPAD Technology, it is the reliable option to auto led illumination.
