  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.
