Sometimes people will use abbreviation MCPCB, instead of the full name as Metal Core PCB, or Metal Core Printed Circuit Board. And also used different word refers the core/base, so you will also see different name of Metal Core PCB, such as Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB and Metal Core Board and so on. MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a Thermally Conductive Dielectric Layer.
The PCB assembly process is a combination of the SMT(Surface Mounting Technology) process and the DIP(Dual In-line Package) process. According to the requirements of different production technologies, it can be divided into a single-sided SMT placement process, a single-sided DIP insertion process, a single-sided mixed process, single-sided placement and insertion Mixed process, double-sided SMT mounting process and double-sided mixed process, etc. The PCBA process involves board cutting, printing, patching, reflow soldering, plug-in, wave soldering, testing and quality inspection.

Tg means Glass Transition Temperature. As flammability of printed circuit board (PCB) is V-0 (UL 94-V0), so if the temperature exceeds designated Tg value, the board will changed from glassy state to rubbery state and then the function of PCB will be affected. If working temperature of your product is higher than normal (130-140C), then have to use High Tg PCB material which is > 170C. and popular PCB high value are 170C, 175C, and 180C. Normally the FR4 circuit board Tg value should be at least 10-20C higher than working temperature of product. If you 130TG board, working temperature will be lower than 110C; if use 170 high TG board, then maximum working temperature should be lower than 150C.
