Well, I went out and got my kester no-clean .025 solder and a flux pen. After trying to solder down some 1206 and 603 parts I have one thing to say: What a waste of money. For small parts, hand assembly the old rosin RMA stuff (sticky goo) works much better - things stick, they wet and the solder sucks into every crack drawing the part and centering it over the pad. The no-clean, is truly no clean, no wet, no stick. And, yes, I got the pen to flow. I paint over the pads, it evaporates and leaves behind a faint cloud of powder... Come to think of it, I kind of like the smell of ethanol when cleaning my boards... ---- Larry Barello http://www.barello.net
