Seams and openings in electronic devices provide avenues for rogue energy waves to enter or exit a
device, causing erratic performance. This is known as EMI (electromagnetic interference). Boyd’s
LectroShield conductive foams, elastomers, adhesives, and metal foils are designed to manage
interference energy, improving reliability and efficiency in device performance.
Boyd’s LectroShield Conductive Foams are ideal for applications requiring excellent shielding perfor-
mance as well as high conformability, compressibility, cushioning and tight contact. These are
designed for electronic devices that need soft cushion and tight contact with the conductive function.
