Mirror Aluminum PCB
the mirror aluminum PCB is a substrate which is pressed together with BT material circuit
Layer and aluminum substrate with silver particles. It is the most suitable raw material for
COB packaging.

Advantages
Good heat dissipation: the mirror silver aluminum substrate adopts thermoelectric separation
Technology, and the thermal conductivity of ordinary aluminum PCB with insulating layer is
1W/MK to 3W/MK. the thermal conductivity of mirror aluminum PCB reaches higher 137W/MK,
Which greatly improves the heat dissipation of the chip.

High light efficiency: the reflectivity of the ordinary gold aluminum PCB is 80%, the reflectivity
of the cup hole aluminum PCB is 85%, the reflectivity of the silver plated aluminum PCB is 95%,
and the reflectivity of the mirror silver aluminum PCB is 98%. the mirror silver aluminum PCB
Can make the light of the chip better excited.
