Electrolyics and Impedance/ESR

Re: Electrolyics and Impedance/ESR

On a side note, when you guys remove the PCB of the power supply from the case, do you guys usually desolder the input wires? On my PSU, it seems like the only way to unclip the socket for the incoming AC line and the power switch is to pull them outwards (which is a problem because they are soldered to wires from the PCB). It seems a little awkward to desolder the joints where the lines meet the PCB because the limited space. And if I desolder the joint at the socket, I worried that all the X and Y filter caps soldered to the same joint will fall off and it would be a bitch to put back on. How do the pro's usually handle this??

I usually snip them at the AC socket end then clean tin and prep them with the PCB out.
Also desolder, clean, tin and prep the pins on the back side of the socket with the PCB out.

The legs of the caps should be wrapped around the pins.
That's enough to hold them in place while you resolder the wires.

Just try it...
The worse that can happen is you end up with a bad PSU,,,
,,, which is what you already have.
Make sense?

Re: Electrolyics and Impedance/ESR

nice. I'll give it a try when I my caps get in. Thanks again everyone your help, patience, and bearing with me (especially PCBONEZ for your continued support)! I've learned so much. Now all I need to work on is getting all the glue off the caps and figuring out which solder joints go with each cap (the entire PCB back just looks like a glob of solder. : )
