How Clean is Clean Enough?

A test matrix investigated 12 ionic contaminants in five concentrations to assess the electrical response under controlled heat and humidity conditions. The study used the limits per J-STD-001 for surface insulation resistance. The tests determined at what level of contamination and spacing the ionic/organic residue has a failing effect on surface insulation resistance.
