Years ago, when I worked for “Big Blue” Computer Co., we sometimes used a paste solder that you put on the joint and then applied heat and it made a tight neat solder joint. Appearently it was ground up solder in a liquid rosin paste.
Has anyone run onto this? If so, what is it called? Where can I obtain some? What is a brand name?
The stuff is great for making neat, quick solder joints on rail as well as electronics.
I don’t time atm to look it up, but I belive Tix makes soldering paste, along with liquid flux and some very fine diameter solders. Check http://www.micromark.com/
I still use solder paste for certain mrr applications. I have a tube of silver based solder paste I picked up some years ago. I keep the tube in the freezer and onlu use it once in a while. It sure was nice to smear a thin coat along the leads of a chip. Touch a hot iron to each lead and the solder would flow perfectly. With a clean hot tip, no solder bridges.
I had a tube of that silver bearing paste solder, but I never could get satisfactory results from it. But the salesman who sold it to me sure could solder paperclips with it, using a lighter!
