Quality Killers in PCB Manufacturing – Photoresist Semi-Polymer In the PCB manufacturing process, many tasks require the use of “photoresist materials,” including inner layer wet film, inner layer dry film, outer layer dry film, and green solder mask. It is a chemical material that, after exposure to light, produces different solubility in the developing solution … Read more
In hardware design, PCB design is a very important and indispensable step. For some simple products, PCB design may simply involve connecting all components and networks accordingly. However, for high-speed circuits and RF circuits, the design of the PCB directly affects whether the product functions properly and whether it meets market requirements. Below, I will … Read more
The main conductor material used in PCBs is copper foil, which is used for transmitting signals and currents. At the same time, the copper foil on the PCB can also serve as a reference plane to control the impedance of transmission lines or as a shielding layer to suppress electromagnetic interference (EMI). Additionally, during the … Read more
