The thermal management of LED PCB board you should know
Because LED efficiency is lost as temperatures increase, thermal management is the biggest problem with LED PCB board.
Frank have asked decades’ experience MCPCB experts about the thermal management.
This post is a summary of the experience of MCPCB experts.
Normally, there were some distinct technologies for LED PCB board thermal management.
Heat dissipation is accomplished on conventional FR-4 circuitry through the use of thermal vias, which transfer heat from the top side of a large heat dissipating copper plane on the bottom of the PCB.
The material of LED PCB board head dissipation via
In fact the LED PCB board has three layers, and the hole through those three layers.
You know difference layer was use different materials.
Here Frank introduces the material is usable hole plugging.
Hole plugging these thermal vases with various epoxy compounds is often employed.
