Soldering 2 pieces of square wire sterling together at the ends at about 30 or so degrees to each other, and after I finish and clean up the piece, there's now a 'hole' right in the inside corner where the silver wire has been eaten away coming into the joint - looks like a cartoon key-hole instead of a crisp angled or slightly over-filled corner, if you can visualise that.
Was using solder paste from Cookson, first joins with hard solder and second with medium solder - all 4 joins that I made showed the same issue to some extent - it really does look like the silver has been dissolved/etched out.
Any ideas what I'm doing wrong here? I'm sure it's got to be me...
Thanks for any suggestions goodly peeps. Be well!
Shaun.
