I am working on micro-size parts that challenge perspective perspectives when trying to describe to others. Imagine an EIGHT conductor plug that can fit perhaps 15 (or 20) pieces atop a postage stamp. Remember, each plug has eight pins. Jeez now to describe the pins :(
First, before solder each joint CLEAN THE TIP ! Use a damp sponge or a damp rag to wipe it clean. The tip should be shiny with solder before attempting a connection. You need an iron with some kind of heat control. Either feedback to a built in temperature controller or even the old fashioned irons that the Curie Point to control temp.
Second, use the "old fashion" tin/lead solder. Anything else is a pain in the butt ! Available on eBay for sure.
What most "makers" on YouTube use is a TS80 or a TS100. Not cheap.
