According to the location of the metal core and the trace layers of the PCB,MC PCB can be divided into 5 kinds.
There are 5 main types of metal core PCB :
1. Single Layer MCPCB (one trace layer on one side),
2.COB LED PCB (one trace layer),
3.Double Layers MCPCB (two trace layers on one side),
4.Double Sided MCPCB (two trace layers on both sides),
5.Multilayers MCPCB (More than two trace layers on every board).
