Find additional information at pcb manufacturer. The white silkscreen layer is applied on top of the soldermask layer. The silkscreen adds letters, numbers, and symbols to the PCB that allow for easier assembly and indicators for humans to better understand the board. We often use silkscreen labels to indicate what the function of each pin or LED. Silkscreen is most commonly white but any ink color can be used. Black, gray, red, and even yellow silkscreen colors are widely available; it is, however, uncommon to see more than one color on a single board.
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. Equipment: We purchased many advanced, art-of-state machines & devices for PCB manufacturing, checking, to improve the quality of our boards.
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.
According to different manufacturing method, current there’re three basic types for ceramic board: A) Thick Film Ceramic Board Thick Film Ceramic PCB: Using this technology, the thickness of conductor layer exceeds 10 micron, more thick than spurting technology. The conductor is silver or gold palladium, and was printed on ceramic substrate. More for Thick Film Ceramic PCB. B) DCB Ceramic Board DCB (Direct Copper Bonded) technology denotes a special process in which the copper foil and the core (Al2O3 or ALN), on one or both sides, are directly bonded under appropriate high temperature and pressure.

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.
