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 EMI Absorbers are designed to eliminate unwanted electrical “noise” in an
electronic device. Different to shielding solutions, EMI Absorbers are intended to absorb unwanted
energy, controlling and minimizing internal interference and crosstalk, and are commonly used as
last minute fixes to manage EMI concerns where device redesign is not possible. Absorbers can be
flexible or rigid, easy to die cut, are dielectric so they can be used near metals, do not need to be
grounded and available with PSA. For these reasons, EMI Absorber applications are diverse and vary
greatly from more traditional shielding materials and solutions.
