Combination meter capacitor

i reported your post, and asked that it be moved to gen 2 forum where more experts might view it, all the best!

 

Why ??

Most any rosin core solder should be fine.

 

I think I would agree with that. Solder is solder.

 

i use electronic solder from radio shack, cause i have no idea what i'm doing. otherwise, i'd be using plumbing solder.
the electronic solder is very fine, which is nice around small areas and wires.

 

Yep. That's the critical point.
Plumbing solder is ACID core and tends to EAT electronic components.

 

You still have access to Radio Shack? The last one has closed around here a while ago... Or maybe you use solder so infrequently that you still have some Radio Shack stuff from previous century?

I think the OP is worried about PCB corrosion from the flux and/or lead content of the solder. I used Radio Shack stuff until I ran out a while ago and bought some online. You can still buy leaded solder which has a lower melting temperature and is preferred by many old school techs. I personally do not care. My iron handles either kind well.

It would be nice for the OP to elaborate on his question. Otherwise I would go with "(electronic) solder is (electronic) solder" answer.

 

I think you want something like this: Just regular tin-lead solder that melts as low as possible.

Here is my iron

 

Ask for 60/40 rosin core solder. You want a small diameter solder to do your work.

The 60 represents the tin in the solder and the 40 the lead.

Never use acid core solder on electrical or electronic circuits, it is for plumbing.

 

the few radio shacks shown on their store locator are 'authorized dealers' under another name.

i just soldered a wire on my grandsons choo choo train yesterday but yeah, my stuff is all from the 80's.

 

Plumbers might agree, but electronics engineers might have different opinions!

 

Except for looks the length isn't important but like you already know the polarity is important. I would clip it and make it look good if I was doing it.

With a visual inspection did you see anything wrong with the old capacitor? Usually that kind of capacitor gets a slightly bulge in the top when they fail, the new one should be perfectly flat.

 

I am into model RC aircraft and people don't like that lead free solder.


Start watching at 4:20 for a demonstration.

 

IF......the "lead free" solder is tin and silver, it certainly would not "suck".....except for the price, that is.

And the polarity of the capacitor leads are marked on that plastic cover around it, down near the bottom where the leads are.

 

that's where my flux and solder are from, building electric planes in the 80's. my, how times have changed.
