Old video and I don't remember the details but generally components like voltage regulators which dissipate a lot of heat are screwed to a large metal plate as a heatsink....the heat some of these components would damage the material from which printed circuit boards are made, and as such that naterial would be a very ineffective heatsink! Does that answer your question?
Hang on I’ve just figured out what you meant - the position of the haemostat, right? M not totally clear on the physics but I think the heat dissipates quite evenly across all the conductive metal, therefore heat is drawn away from the delicate semiconductor regardless of which side of the pcb you place the haemostat. So maybe what you suggest would be slightly more effective, but from experience what I show I. This video is good enough, thanks for watching.
@@Tetrakan yeah, that’s what I meant. To be honest, whatever keeps the heat away from transistor bodies is good in my book. Thank you so much for replying. Much appreciated 👍
Good tip! Here's one I can share that's in the scope of this video. A trick for preventing a wires insulation from melting back or to stop heat shrink shrinking because it's too close due to limited wire length, a v paper clip clamped down on the wire as close to the exposed section you plan to solder works really well too, so long as it's a metal clip ofcourse.
If you clip leads after soldering they must be reflowed or inspected under 10x magnification to assure the solder was not fractured when leads were clipped.
Thanks for this video. Should the heatsink not be between the main body of the component and the PCB?
