Plasma not only effectively removes organic contaminants on the surface of polymer materials, but it is also used for fine cleaning of organic contaminants on the surfaces of PCBA and […]

The increasing functionality of mobile phones places higher demands on PCB design. With the arrival of Bluetooth devices, cellular phones, and the 3G era, engineers are focusing more on the […]

Radio Frequency (RF) printed circuit boards (PCBs) are high-speed circuits operating at frequencies of 100 MHz and above, often ranging from 500 MHz to 2 GHz. RF PCBs are the […]

Today, the reduction in the size of basic circuit boards will allow designers to shrink their PCB dimensions by half, or even down to a quarter of the original size. […]

The internal resistance testing is actually quite similar to the AC impedance testing method. The principle is essentially based on the volt-ampere method, which means calculating the impedance by dividing […]

In the PCB reverse engineering process, sometimes the film may deform due to failure of temperature and humidity control or excessive heat rise in the exposure machine. If the process […]
