I recently repaired a Soviet TV, the entire pcb was 90 degree clinched. Absolute nightmare to replace the capacitors, many torn pads later and it's fixed. Why would they do that? It's a portable b/w set from '91 with 2 integrated circuits, so it's kinda modern.
hello. I am a student majoring in electronic engineering in Korea. The waveforms of the Colpitts circuit implemented with pspice and the Colpitts circuit implemented with a breadboard are different. Do you know why? And the waveform of pspice is the same regardless of whether R1 and Rf are present. Do you know why?
Superb training video. We all want our solder joints to be reliable...but it also teaches us what to look for in searching for bad joints.
I sometimes spray paint the non copper side of phenolic paper protoboards for aesthetics 😏
I was just about to try that for the first time. Have you had any problems?

Why is so much flux used nowadays ? The flux in the solder cores always used to be sufficient for clean boards.
NOT THE THING FOR ME BUT,GOOD LECTURE.
