Re: Advice on replacement caps for Netgear WNDR3700

a tip should not be damaged with normal electronic solder, only if someone is using a very agressive flux that shouldnt be used on pcb's
aluminium or stainless-steel solder comes to mind.

That is why I asked the question. Sometimes people just starting into electronics do not know the difference.

What type solder are you using? I always use a homebrew heat controller on my irons so as not to burn them up when the full amount of heat is not needed.

60/40 rosin flux core.

I've got an old, cheap RS soldering pencil around here somewhere with a screw-in tip with a set-screw. Long ago I used a brass screw for a tip and filed the end to a pyramid tip. It worked great but it definitely pitted quickly using 60/40 rosin core solder. I had to file it down every once in a while.

Good luck and please report back.

Man look at that prices!! I got everything WAY cheaper. And in D10x20 I even got higher capacity (680) in 35 V.

BTW I still cannot see any pictures in the first post.

FWIW, I just opened the wall-wart for this router, and none of the caps inside are bulged.

Have you measred capacitance/ESR? No visual signs still does not mean they are not long bad.

Re: Advice on replacement caps for Netgear WNDR3700

No, I haven't done that, as I do not have the means to. I know it is no guarantee they're not bad, but how likely is it that they failed without swelling? I thought that was relatively uncommon; is that wrong?

Thanks!

Not really, especially small caps usually dry out and increase ESR/decrease capacity to insane levels. I've seen 10uF cap having less than 0.1 uF and ESR more than 150 ohm.

I fabricate my own tips out of solid copper, no steel or iron at all. They work just fine as do the brass tips that I make.

Thought I was odd fabricating tips from copper since those Hakko tips are scarce in this crappy country am at.
