Will the design error of screen printing position number affect PCBA patch processing? It can be clearly said that the screen printing position number does not determine whether the final patch is correct.
Zte is supported by China's National Integrated Circuit Industry Investment Fund, which undoubtedly speeds up the process of ZTE's independent research and development of chips; Before this, Huawei has launched its own Kirin 950 chip, which intends to com
In the power supply circuit, the positive electrode of the electrolytic capacitor is connected to the output terminal of the power supply when the positive voltage is output, and the negative electrode is grounded.
Hongyunlai Electronic technology to give you the best quality SMT patch processing,PCB production, embedded system research and development, electronic processing, embedded motherboard,PCBA contract materials, Guangzhou PCBA processing services.
Power layer copper is a faster and easier option for most PCB design software. By sharing a large number of wires, maximum efficient current with minimum impedance or voltage drop is guaranteed, while providing an adequate grounding return path.
While there are a few tricks that can reduce the cost of assembling PCb as for PCBS, sometimes price is the main factor in our final decision. When selecting PCB rooms, the cost must be analyzed from two aspects: the overall offer - don't just indulge in
The layout of the basic structure such as PAD, design rule check (DRC), parameter extraction (EXT) and layout circuit control (LVS) associated with the design tool are the key to the successful production of the designed chip in the wafer factory. This is
Field observation is a practical investigation method, which is of great reference significance for the internal self-understanding and improvement of PCB manufacturers, as well as the understanding and selection of suppliers.
Factors affecting PCB price: First, PCB materials used in different price diversity, second, PCB production process used in different price diversity, third, PCB itself difficulty caused by different price diversity, four, different customer requirements
