PCB direct plating process introduced

PCB direct plating process introduced (A) Faraday's law The first law - when the plating bath (electrolysis), "attached" on the cathode metal weight (or anode erosion) is proportional to the amount of electricity passed. The second law - in the different bath plating with the same amount of electricity, [...]

PCB technology electrolytic capacitors and capacitors

PCB technology electrolytic capacitors and capacitors one. Fixed capacitor: refers to once made, its capacitance can no longer change the capacitor. Capacitors can generally be divided into non-polar ordinary capacitors and electrolytic capacitors with polarity. Ordinary capacitors are divided into fixed capacitors, semi-adjustable capacitors (trimmer capacitors), variable capacitors. Capacitor [...]
