Solitary Layer PCB vs. Dual Layer PCB in Automotive LED Headlight Bulbs


In generally, FR4, Aluminum PCB and Copper PCB all can be made into single layer PCB or double layer PCB
Solitary Layer PCB
Single layer PCB is the most frequently used, since it is easy to style as well as practice.

This PCB covered a conducting material on the one side of the board. Single layer PCB with a great warmth dissipation, each chip dissipates warm on one PCB, the LED headlight can be in a high lumen.

Yet the size of two chip of 2 solitary layer PCB is too large that mores than 3mm. Restricted by the size, it can not imitate the halogen light bulb tungsten wire, the light beam is not clear with a dark location.
Double Layer PCB.

 

  • This PCB covered 2 carrying out product on the both side of the board. It supplies a more detailed range in between both side of the chips, which is similar to the thickness of halogen light bulb tungsten cord. For this outcome, it mimics the halogen light bulb light-emitting kinds, the light beam is a lot more better. Nonetheless, the both side of chips dissipate warm on one PCB, the warm could not be expensive, so it restricts the lumen for LED front lights.

It is not rely upon the location of PCB concerning the PCB warm dissipation problem.

 

Thermal Management modern technology is another core component of PCB application. In the next write-up, I will certainly review thermal monitoring Printed Circuit Board (PCB) technology, especially SINKPAD Technology, it is the efficient solution to auto led lights.
