Whenever a module contains "C"-shaped pins on the sealing surface, any effort to seal that layer, i.e., surface, with the sealing epoxy, particularly SCOTCHCAST*, resulted in the pins becoming embedded in the epoxy, thereby reducing the compliancy of these pins. This encapsulation of the "C"-shaped pins is caused by the capillary action of the Scotchcast on the pins. Anytime the epoxy touches a pin, by capillary action, it moves up and over the pin like a "wick".
