Electronic Component Porosity Explained

Electronic and electrical components need to be protected against water or chemical ingress which can cause corrosion, short circuits and component or system failure.

Microscopic gaps and cracks can result from the assembly of dissimilar materials with different expansion coefficients when exposed to temperature cycles. Ingress occurs when moulded plastic shrinks slightly, opening leak paths around metal pins or inserts.

Impregnation is the permanent solution to sealing cracks, gaps and leak paths in electronic and electrical components.
