FR4 vs. Light weight aluminum PCB applying in automobile lights

July 23, 2018

Cost Comparison
In the expense contrast, the Aluminum PCB is extra expensive than FR4, along with more exceptional in efficiency.

Thermally Conductivity Comparison
Aluminum PCB has an excellent capability of thermally conductivity compared to FR4 makings them play a crucial function on LED lights technology.

Innovation Practices
The thermal conductivity dielectric material of Aluminum PCB is a thermal bridge that attaches the components and also steel plate. It can transfer warm to the warmth sink with the core immediately. An Aluminum backed PCB is put together with light weight aluminum support, highly thermally conductive dielectric layer and common circuit layer. The circuit layer is a thin PCB bonding to the aluminum backing. When It Comes To FR4 PCB, it takes typical machining techniques: drilling, routing, v-scoring, countersink counterbore. So it requires an added warmth sink to carry out heat in from the circuit layer. Or it will a possible destructive hotspots.
