Printed circuit board assembly manufacturer today? The layer on top of the copper foil is called the soldermask layer. This layer gives the PCB its green (or, at PCB & MCPCB, red) color. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. This layer helps the user to solder to the correct places and prevent solder jumpers. In the example below, the green solder mask is applied to the majority of the PCB, covering up the small traces but leaving the silver rings and SMD pads exposed so they can be soldered to. Soldermask is most commonly green in color but nearly any color is possible. We use red for almost all the PCB & MCPCB boards, white for the IOIO board, and purple for the Best Technology boards.

What we provide is not only PCB & MCPCB manufacturing, but also including PCB duplicating, Engineering & process design, components management & sourcing solution, PCB in house assembly & full system integration, surface mounted technology (SMT), full products assembly & testing.
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.
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.
Despite all the precautions, damage to the Flexible PCB can occur. That is why one should constantly check for faulty components by testing all components to figure out the faulty ones and then replacing them so that the board functions well. Every so often, the issue could be caused by bad soldering. In such cases checking the soldering condition and repairing it works well. While components and soldering failure are easier issues to tackle, you could also be dealing with a complex circuit issue. If the circuit is indeed the problem, the PCB must be returned to the factory for the necessary repair. These are the most probable factors that may have caused your flexible PCB some damage. When you take care of such factors beforehand, you can avoid damages to your PCBs and save time and effort for your organization. To develop sturdy and long-lasting PCBs, it is always recommended to choose a reputed PCB Fabrication company that develops sturdy PCBs for you that have rare chances of getting damaged.
Flex PCB ( FPC ) is stands for Flexible Printed Circuits, or sometimes we just call it Flexible Circuits or Flex Circuits, which is the electronic component developed to allow electronic goods to become smaller and lighter, and it have been widely used from 1980s in USA & Europe, and then widely spread out around the world. Since flex circuits (flexible circuit) has excellent working efficiency and strong heat-resistance, it is widely used as a core component of all electronic goods such as cameras, computers and peripheral equipments, mobile phones, video & audio units, camcorders, printers, DVD, TFT LCD, satellite equipment, military equipments, and medical instruments. Anyway, Best Technology flex pcb manufacturer will provide OEM/ODM service.
