In PCBA chip processing, the amount of solder paste, chip glue, and component losses should be managed as one of the key process control contents. PCBA processing and production directly affect the quality of products, so it is necessary to control factors such as process parameters, processes, pers

Rx is a resistor, there are many resistors in the circuit diagram, according to the serial number, R1, R2...Cx is a non-polar capacitor, anti-interference capacitor at the input of the power supply;IC integrated circuit module;Ux is an IC (integrated circuit component);Tx is the test point (for fact

A printed circuit board (PCB) is an electronic component that connects different electronic components together. Designing a PCB is a complicated process that requires high precision. In the design process, some common errors will inevitably occur. These error problems are to help everyone avoid the

Most of the PCB boards we see every day are green, but in addition to green, we can occasionally see blue or even black PCB boards. Why exactly choose different colors for PCB board? Why is green the most common color? This article will reveal the secret behind the "colorful" PCB. Green ink is by

PCB design requires different grid settings at different stages. In the layout phase, large grid points can be used for device layout.For large devices such as ICs and non-positioning connectors, 50 to 100 mil grid precision can be used for layout. For passive small devices such as resistors, capaci

Multilayer boards are the most widely used type of board in daily life. So what are the application advantages of multi-layer PCB circuit boards:
