According to the experience and insights I gained while repairing the circuit board, I would like to share with you friends. Our friends who have repaired electronic products know that in a complete electronic product, there is usually a piece of circuit board that is placed in different positions in the electrical appliance according to [...]
Circuit board proofing (PCB proofing) refers to the trial production of printed circuit boards before mass production. The main application is the process of small-scale trial production by the electronics engineer after designing the circuit and completing the drawing of the PCB to the circuit board factory. Proof for board (PCB proofing). Circuit board proofing [...]
Yesterday, a physical experiment instrument was dismantled, and the EDM timer was used. The error mark on the instrument label was the electromagnetic dot timer. After dismantling and analyzing from the structure diagram, it can be seen that there is an electronic circuit inside, and the working power source is 220 volt AC, which is [...]
