Pcb assembly manufacturer right now? Most of our engineer and operators has more than ten years of experience in PCB industry, so we can produce special such as 20 OZ heavy copper board, 4 layers MCPCB, etc. At the same time, we purchased many advanced, art-of-state machines & devices for PCB manufacturing, checking, to improve the quality of our boards. Find additional information at pcb assembly service. Currently our mouthy capability is 260,000 square feet (28,900 square meter), more than 1,000 different boards will be completed. We also provide expediate service, so that urgent boards can be shipped out within 24 hours.
Best Through Hole Technology assemble more than 50 kinds components Factory Price. We offer a complete range of through hole PCB assembly capabilities in compliance with IPC quality standards. We provide Through Hole Technology (THT) PCBA service at the highest quality level and in a cost-effective manner. Our through hole technology (THT) PCB Assembly services includes both manual and automated techniques. While our manual soldering techniques can handle complex assemblies, the automated ones are best suited for high volume production as well as reduced material handling. We provide THT PCBA service at the highest quality level and in a cost-effective manner.
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.
Best Technology wholesale fr4 pcb manufacturer specialized in many kinds of fr4 board and provides fr4 pcb assembly service since 2006. Please contact Best Technology fr4 board suppliers anytime and get quotes! FR-4, is a widely acceptable international grade desination for fiberglass reinforced epoxy laminated that are flame retardant (self extinguishing). After add copper layer on one or each side FR4, it become to Copper Clad Laminate (CCL), and this is the non-conductive core materail for normal printed cricuit board (PCB). Printed circuit board using FR4 as core material will be named as “FR4 PCB”. Wholesale fr4 pcb board is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper clad laminate substrate. Sometimes, PCB also named Printed Wiring Board (PWB) or etching wiring board if no extra electronic components was added on. See more information on https://www.bstpcb.com/.
The main difference between a FR4 board and MCPCB is the thermal conductivity dielectric material in the MCPCB. This acts as a thermal bridge between the IC components and metal backing plate. Heat is conducted from the package through the metal core to an additional heat sink. On the FR4 board the heat remains stagnant if not transferred by a topical heatsink. According to lab testing a MCPCB with a 1W LED remained near an ambient of 25C, while the same 1W LED on a FR4 board reached 12C over ambient. LED PCB always be produced with Aluminum core, but sometimes steel core PCB also be used.
