On the way to a train show today, my friend asked if I knew anything about Micro-Mark soldering paste, #60664 on pg 16 of the current catalog. His hands shake some, making regular soldering difficult for him. He thought if he could put it on, then only have to hold the heat source he could manage to solder. Since he and computers don’t get along together, I told him I would ask here on the forums and see if anyone had any experience with it.
I know liquid solder has not gotten a very good reviews in the past, don’t know if this is the same or not.
Has anyone used this product? Did you feel your results were successful?
Many years ago, I bought a small tube of soldering paste and experimented with it. It seemed to be a thick mix of powdered solder and non-acid paste flux, stayed where I put it and performed adequately. I haven’t used any since, but see where it might be useful.
Much more recently, I saw an episode of How It’s Made where soldering paste was used to assemble police whistles, basically to get solder to the otherwise inaccessible interior of the assembly. The process was automated, and the whistles were heated with a pretty potent flame while being rotated to distribute the molten solder.
I might have to get some to experiment with again. I have some non-standard soldering jobs coming up.
Silver soldering paste with flux is used in commercial PC board production.
Some home experimenters use a toaster oven for doing SMT work with the same type of solder paste.
I have used solder paste for SMT work. I just slather in over the chip or component leads and let the fine tip soldering iron do its thing. A brush with some alcohol to clean off the flux. It is a learned art, believe me. It is not plug and play.
Do a Google search for solder paste soldering. You will get many commercial and DIY links.
