Formulators of potting materials for aerospace electronics applications are careful not to supply products with entrapped air. Consequently, entrapped air is usually a processing issue which can compromise thermal conductivity and heat dissipation, or the electrical insulation properties. Voids and delamination can also provide pathways for moisture and other contaminates, weaking the physical structure. If […]
