Subject: [TN] Detecting Oxidation Levels of PTH

Techies,

We have one assembly that sporadically experiences insufficient solder
fill of plated through holes at the wave soldering process.

If we cross section one of these, what testing equipment is best suited
to detect the presence of oxidation on the PTH walls?  What would be
considered an unacceptable level that would prevent 100% climb?

Thanks in advance for your responses!

Leland
