I'm in the process of re-chipping my K1 with Zimos and am hitting a problem I often have, which is cleanly soldering fine wires.?
I have an ERSA temperature controlled soldering iron with a variety of tips but often find I can't get a clean coating of solder on the tip nor cleanly tin the end of a wire, and then quickly solder such a wire to the tiny connector pads. I've tried both tin&lead and tin&silver cored solders but suspect this may be part of the problem. Should I stick with tin&silver with a dedicated tip? And what size tip is best and should I use any flux?
I would really appreciate some advice from experienced chip fitters.
John
