It is the most popular production process in SMT electronic assembly industry, which meets the requirements of thin and mass production of mobile phones and computers. PCBA assembled by SMT patches has high relative density and light weight, and has completed mass production of automation technology. Characteristic spot welding is on the same plane as […]

The package plays the role of installation, fixation, sealing, chip protection and electric heating performance enhancement. In addition, according to the contacts on the chip, the pins are connected to the pins of the packaging case by power lines, and the pins are connected with other components according to the power lines on the printed […]

In the production process of FPC, if you don’t pay attention to touching the PCB pads with your fingers, especially the FPC with surface treatment, it will cause oxidation. When the FPC board surface is oxidized in the case of soldering components, it is very easy to fall off and be scrapped. Because the finger […]

BGA for SMT processing is a kind of packaging method. BGA is the abbreviation of English BallGridArray, which is translated into Chinese as ball grid array package. In the 1990s, with the continuous development of electronic technology, the processing speed of IC has been continuously improved, and the number of I/O pins on integrated circuit […]

Definition of making high frequency circuit board High-frequency circuit board refers to a special circuit board with high electromagnetic frequency, which is used for PCB in high-frequency (frequency greater than 300MHZ or wavelength less than 1m) and microwave (frequency greater than 3GHZ or wavelength less than 0.1m) fields. It is a circuit board produced by […]
