Ive found that on jlpcb boards if you solder at 310 and don't drag solder you will get 100% success rate and even the 7ctn chips will test at 150mhz ( which they shouldn't i know). However, if you dwell too much and especially at higher temps then you damage the boards. I got someone at work to check these boards out under their fancy microscope and confirm this. Sadly i didn't keep the images
So in summary. If you don't want to spend an evening soldering,checking, soldering,checking, soldering,checking etc then solder at 310C and don't dwell.
hope this helps someone
I cannot confirm this. I use 400C for manual soldering and have no problems. Time after time i even desolder the chips by hot air and solder back. Still no problems.
I think result may depends on flux used and how good it was cleaned.
and i was jumped on , on classic gaming discord for saying i soldered @ 400c haha , funny how folks are quick to jump to there own conclusions, ive been soldering for years at these temps and never had any problems, also used chipquick to re-use smd parts
ha ha. I have also been wearing my lucky moose socks that i got when on holiday in new hampshire, usa a few years back. Is this the key to the error free 128mb boards ?
