  • Abstract
    Under high humidity service or test conditions typified by MIL-E-5272. commercial epoxy-glass circuit laminates degrade in insulation resistance. Leakage currents often increase to values unacceptable for high impedance circuits. Insulation resistance is comprised of two components in parallel: Surface and volume resistance. Surface resistance is usually controlled by cleaning and the use of conformal coatings. Volume resistance has been little studied and is here investigated in some detail.
