Before Cleaning All connectors on the circuit board including jumper plug, card board, battery and IC must be carefully pulled out before cleaning. Potentiometer, transformer and solenoid coil (inductive coil) must also be removed from the circuit board. Note: non electronic professional do not do this operation, because if there is no electronic professional technology, …
Fault Characteristics and Maintenance of PCB Capacitor Damage The fault caused by capacitor damage is the highest in electronic equipment, especially the damage of electrolytic capacitor is the most common. The damage of capacitance is shown as follows: the capacity becomes smaller, total loss of capacity, electric leakage and short circuit. Capacitors play different roles …
Because most of the modern printed circuit boards have no official schematic and more and more chip applications with programs, engineers will face challenges in various aspects. Through a lot of practice, there are still ways to avoid these challenges. I will share 6 maintenance methods of PCB. Tip 1: Appearance Inspection Looking, asking, smelling …
