Hello Technet,
1) I would like to better understand the relationship between smooth and
shinning solder
joints and reflow profile.eg: i've used different types of no-clean
solder pastes and observed differences in the solder joint
finish.Some are smooth and shinning while
others are somewhat dull and have scratchy lines on the solder
surface.i've tried to increase the soak zone dwell time but have not
been able to improve the finish.
2) can you also tell me if there will be any difference between sn63 and
ag2 % alloys
with regards to the shinning joints?
thanks.
kelvin.
