That's pretty vague and broad, Mr. Peru. If you can provide more specifics it will be more likely that a reader can help you. Thanks.

Hi, Vinod. The most basic principle is that the components must not move during the critical second or so while the solder is cooling. Are you sure that the parts are firmly held in place rather than relying on the operator to hold them still? But there are very large books written about soldering problems, so I won't pretend that your problem is necessarily solved easily.

Q. We are doing manual soldering of PVC insulated copper wires ( 0.20 mm CSA ) on copper parts by preheating the copper base & using soldering iron with solder wire dia of 0.8 mm having Sn ( 60 ) / Pb (40 ) with flux content of 2.2%
We are recently facing lot of dry solder issues in spite of strong process control & 100% manual pull test of wires after soldering . Is there any atmospheric effect on solder joint after soldering which can cause this issue ?
