Soldering Help


Hello, 

I am going to try soldering a connection in my preamp.  I don't have any equipment to do this.  I am looking for advice on materials.

I did read that I want to avoid solder with lead in it.

What soldering tool, solder, etc would people recommend? 

Thank you!

I have several soldering stations and use either Cardas solder or Wonder solder. If you live outside of the Boston area I'd be more than happy to help out. Just PM me.

You got good advice on what to use. My question is, Why? Before you go applying a lot of heat it is good to know where and what and why? Because you can buy all the greatest gear, and then if you don't know what you're doing easily overheat a trace and trash a circuit board. 

My advice is once you get your stuff take a few wires twist them together and practice soldering. Get a feel for how heat flows into metal and how solder flows to the heat. What you want is to get the part hot enough all you do is touch the solder and it flows right into the joint. But not so hot it starts melting plastic and insulation. Takes a little practice to get the hang of it which is why I suggest start with scrap wire not expensive preamp.

+1 on Cardas Eutectic and WBT.

All silver solder I've see contain lead.

Practice makes perfect

It’s always a great opportunity to learn, add an accomplishment, increase your self worth. It’ll sound much better if you do the job yourself!

If tight or tricky, not one to learn first: my local electronics parts store will make repairs. or, a computer repair shop. you may have a source close for this.

during deep covid, the repair dude worked from home, so I dropped a tricky job off, out, back in, pickup.

is it just a ground, not important signal path? there are conductive adhesives you could use for a semi-permanent fix, scrape it off and re-do later.
