If you're using the Kapton tape to protect the gold fingers from solder splatter, my first instinct is to say,yes, you do need it. I've had the pleasure of paying to have gold fingers reworked in the past. It is not in-expensive; certainly not equa

I had someone in another forum tell me that my assembly would fail if I had a few solder joints over the 1000ppm RoHS threshold, with all other solder joints within spec. So, I followed up with this illustration. Please let me know what you think.

Which type? * Solder beads (mid-chip solder balls, attached to the waste line of your chip caps and resistors) This is more paste volume related. * Solder balls that tend to be more randomly scattered (as in spattered)? This tends to be more profile

You are mixing long exposed paste back into fresh? How long has your fresh jar been open to the air? You are probably doing yourself a disservice by scavenging the paste (it could have moisture entrapped). Your visocity has definitely changed. You a
