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.

Our automated X-Ray inspection systems are able to monitor a variety of aspects of a printed circuit board in assembly production. The inspection is done after the soldering process to monitor defects in soldering quality. Our equipment is able to “see” solder joints that are under packages such as BGA, CSP and FLIP chips where the solder joints are hidden. This allows us to verify that the assembly is done correctly. The defects and other information detected by the inspection system can be quickly analyzed and the process altered to reduce the defects and improve the quality of the final products. In this way not only are actual faults detectd, but the process can be altered to reduce the fault levels on the boards coming through. Use of this equipment allows us to ensure that the highest standards are maintained in our assembly.

With our advanced equipments and strong manufacturing capability, we’re able to provides an extensive range of PCB fabrication,PCB design and service, the printed circuit boards we manufactured include: from simple single sided PCB, double-sided PCB to complex multilayer PCB up to 30 layers, Metal core PCB, Flexible PCB, Rigid-flex PCB, HDI PCB, Microwave RF PCB and so on, the pcb assembly service we offer based on our assembly plant include: SMT, thru-hole, combo of SMT and thru-hole, consigned pcb assembly, partial consigned pcb assembly and full turnkey pcb assembly.

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.
