Spot Soldering for Artzy Projrects

Posted by: @gtmize

I’m trying to duplicate spot soldering to build Artzy things.  I cannot seem to hold a bead of solder on my Iron to apply to each component ( resistor, transistor..)   Is the type of solder, temperature, flux ? sites like Apour Maker

Is that two questions?

The first being how to 'hold' a bead of solder? I have a special tip for that which has a concave surface that holds quite a large bead.

Is the second question related to what kind of solder, temperature and flux are best for soldering parts? The answer is 63/37 solder 600F to 650 F and proper flux. I use mostly liquid but if you can find NON fake paste then that is good too. It doesn't last long even if kept in the refrigerator to prolong it's life.

@zander Thanks .. Maybe it just takes practice 🤨

@gtmize Was I right about two questions?

For non artsy use, otherwise known as normal soldering, you do NOT apply solder to the tip, you use the tip to heat the joint (where 2 or more metal parts are joined) then push the solder against the hot parts. It works almost instantly if you use liquid flux and thin solder. I have 0.38mm 63Sn/37Pb with 2.2% flux core for tiny parts like resistor or capacitor leads and of course some pins. Then I have 0.8mm for larger things. It is 60Sn/40Pb with 1.5% - 2.0% flux.

I don't know what your artsy application or technique is, but if you really need a large ball of solder, then get a point with a concave tip. I have a couple, I use them for soldering surface mount devices.

Perhaps you can tell me more or show some pictures of your art work.

@gtmize I forgot, yes, it does take practice, but you can by solder practice boards. Have a look at this one https://amz.run/8kko
