MT77 High Speed PCB Manufacturers

BCM89551B1BFBGT is a high-performance automotive Ethernet switch chip launched by Broadcom, which plays a key role in today's intelligent devices.

The covering film of FPC circuit board shall be processed by opening the window, but it cannot be processed immediately after being taken out from the cold storage. Especially when the ambient temperature is high and the temperature difference is large, water droplets will condense on the surface.

A semiconductor is a substance with a conductivity between that of a conductor and an insulator. It is not very conductive in a pure state, but its conductivity can be adjusted by adding impurities (doping) or changing the temperature. The typical representative of semiconductors is silicon, which is widely used in the manufacturing of electronic components. Semiconductor technology is the cornerstone of modern electronic devices, such as smartphones, computers, digital cameras, etc., all rely on semiconductor chips. In addition, semiconductors are also very important in the energy field, such as semiconductor materials, which are the core of solar cells

Our common computer boards and cards are basically epoxy resin glass cloth based double-sided printed circuit boards. One side is the plug-in components, and the other side is the welding surface of the component feet. It can be seen that the welding points are very regular

At present, the coating method of resist is divided into the following three methods according to the precision and output of circuit graphics: screen missing printing method, dry film / photosensitive method and liquid resist photosensitive method.

Semiconductor is the foundation of modern electronic technology, and its development can be traced back to the late 19th century. This article will introduce the development history of semiconductors and explore their importance to modern technology.
