Depending upon the shape, density and height of pins on circuit modules, the back sealing material known as "Scotchcast" may climb up or "wick" up the pins when applied to the module, to act as a protective backseal coating against corrosion of the metals used on the ceramic substrate of the circuit modules. The unwanted rigidity of the pins can cause unacceptable stresses at the card solder joints.
