Car PCBA Manufacturers

Due to the continuous introduction of thin, light and short products in the market, the high-function, high-speed and other double-height era has been developed, and the trend of high-frequency, high-speed, and multi-IO chips has been developed.

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.

Semiconductor materials refer to materials with special electrical properties in electronics and quantum mechanics, including silicon, germanium, silicon nitride, gallium selenide, etc. The special properties of these materials enable them to be used as materials in electronic devices, such as transistors, diodes, solar cells, etc.

Germanium, silicon, selenium, gallium arsenide and many metal oxides, metal sulfides and other objects, whose conductivity is between conductor and insulator, are called semiconductors. Semiconductors have some special properties. For example, the thermistor (thermistor) for automatic control can be made by using the relationship between the resistivity and temperature of the semiconductor; Using its photosensitive characteristics, photosensitive elements for automatic control can be made, such as photocells, photocells and photoresistors

Chip classification Is there a systematic classification method for so many chips? There are actually many ways to classify chips

Under the background of chip shortage, chip is becoming a crucial field in the world. In the chip industry, Samsung and Intel have always been the world's largest IDM giants (integrating design, manufacturing and sealing and testing, basically without relying on others). For a long time, the Iron Throne of global chips was fought back and forth between the two until TSMC rose and the bipolar pattern was completely broken.
