Several points are: * There can be a seasonality to the venting of [smells emanating from] wave solder machines, because the heating and cooling of your plant changes with season. * Supplier's specification for your wave solder machine defines the pr

I'm somewhat frazzled by this one, not being too familiar with the MYs. Head is clean, tried different tools, same tool# from another MY, and have run the Centering Base Level Calibration to no avail. The component heights are correct and the par

Moisture should not be an issue with ceramics, but mechanical or thermal stress definitely is. Has there been rework on this capacitors? So check for handling /temperature of your soldering irons (better:use hot air). Check oven temperature/profile
