//Aluminum base PCB | MCPCB

Aluminum based PCB, also named Aluminium PCB, metal clad(MCPCB) PCB, insulated metal substrate(IMS or IMPCB) PCB, thermally conductive PCBs, etc. It is generally including single layer, double layer and multi layer.

Operating theory:
The power device surface mounting on circuit layer, it is ideally suited for the mounting of high power light emitting diodes (LEDs) easily dissipating the heat generated by power devices.

COB MCPCB

COB MCPCB(known as Chip-on-Board Metal core pcb) is semi-conductor assembly technology, where micro-chip also known as die is electrically interconnected instead of using traditional assembly process or individual IC packaging on the final product board. COB MCPCB used in thermoelectric separation application products. For normal MCPCB, there's a dielectric layer between trace copper and metal core, and the thermal conductivity is limited by that dielectric layers, so value can only be 1~3 W/m.K. But using COB MCPCB, there's no such dielectric layer because chip (die) direct touch the metal core, so thermal conductivity value of COB MCPCB will be [...]
