PCBA Cleaning Process

Inventory of 4 factors affecting the stability of the PCBA cleaning process

Author：Zhou For quite some time, the industry has not been sufficiently aware of the cleaning process. Mainly because of the former PCBA assembly density is low, flux residues and other contaminants on the electrical performance of the adverse effects are not easy to be detected. Nowadays, as the design of PCBA develops towards miniaturisation, the […]

SMD Power Supply Filter Design Tips

What is the purpose of using a filter in a circuit?A filter is a circuit capable of passing certain frequencies while attenuating (to reduce or block) other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant frequencies. In the field of electronics, there are many practical applications for […]
