Hi John,
I use a normal 18watt antex iron and some lead solder with a resin core to solder the wires.?
I personally don’t rate the silver/tin stuff as the silver gives varied results.?
I only stay as long as I have too when soldering the joints to make the solder run as if you dwell too long you can delaminate the pads off the PCB.?
Make sure the wires you are tuning are fresh and clean, if there is any bits stuck to the end of them it’s cut off and re tinned if possible to ensure a good clean joint.?
Hope the above helps?
Thanks
Simon?

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
