PCBA processing tin penetration is mainly affected by factors such as material, wave soldering process, flux, manual soldering, etc., which can be adjusted and solved in the following ways

The easy-to-understand statement of SMT patch processing is: attach capacitors or resistors on electronic products with a dedicated machine, and weld them to make them stronger and not easy to fall to the ground. For example, the high-tech products that we often use nowadays are computers and mobile

With the advancement of technology, some electronic products such as mobile phones and tablet computers have become light, small and portable. The electronic components used in SMT processing are also becoming smaller. The previous 0402 resistors and capacitors have also been used in large numbers.

Today's electronic products are pursuing miniaturization and portability, which requires the core part of these electronic products, the pcb circuit board, to be smaller and lighter, which also requires the use of smt chip processing technology.The quality and reliability of solder joints in smt chi

A complete circuit board is composed of various electronic components, and it will go through many processes from PCB board to finished product, and SMT chip processing is one of the very important ones. To process a qualified PCBA board, you need to pay attention to many aspects. Next, Shenzhen PCB

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
