The difference between manual and automated PCBA testing methods

After PCBA processing is completed, PCBA testing is required. Generally, there are two methods: manual testing and automated testing. So what is the difference between these two methods? Manual testing and automated testing are not actually the opposite, and not all functions need to be automated. Automated testing has been developed for so many years, …

Causes of deformation and warping during circuit board SMT patch processing

The IPC standard stipulates that the maximum allowable deformation of circuit boards for SMT patch processing is 0.75%, and the maximum allowable deformation of circuit boards without SMT patch processing is 1.5%. The circuit board warpage is calculated by: (PCB diagonal Long*2)*100%. Deformation and warpage of the circuit board will directly affect the welding quality, …

Let’s talk about the hazards and protection of static electricity (ESD) during SMT chip processing

With the rapid development of electronic technology, SMT processing technology for electronic products has matured in our country. As electronic products become more and more precise and miniaturized, this means that PCBA lines will become narrower and narrower, and their electrostatic discharge capabilities will become worse and worse. As a result, the requirements for electronic …
