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.
Generally speaking, aluminum is the most economic option considering thermal conductivity, rigidness, and cost. Therefore, the base/core material of normal Metal Core PCB are made of aluminum. In our company, if not special request, or notes, the metal core refer will be aluminum, then MCPCB will means Aluminum Core PCB. If you need Copper Core PCB, Steel Core PCB, or Stainless steel core PCB, you should add special notes in drawing.
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.
