With the increasing proliferation of wireless devices, designers are challenged with various electromagnetic waves from multiple sources radiating at the same spectrum of frequencies resulting in electromagnetic interference (EMI). Radio-frequency (RF) emitting devices require effective isolation to limit the propagation of their interference to neighboring components to protect the end device from performance degradation.

As electronics move toward miniaturization, lighter weight, and higher speeds, these challenges become more significant as conventional shielding methods present functional and operational limitations. To address this, the Faraday cage is applied directly at the package level.

This webinar will cover Henkel’s latest materials, application process, test methods, and performance.

Micro Electro Mechanical Systems (MEMS) are driving the merger of various sensing capabilities into a single device, and are used in many different applications. Largely employed in the handheld sector which is driving MEMS growth, smartphones today can contain as many as ten to twelve — or even more — MEMS devices, with this number projected to grow in the coming years.

Manufacturing MEMS devices is a balancing act, as MEMS die are very sensitive and fragile. Too much stress from die bonding may crack the die and, if the bonding adhesive’s modulus is high, the die can bend due to stress. This flex can cause the moving parts of the MEMS to go out of calibration. To accommodate these stress and modulus challenges, Henkel has developed a silicone material technology for MEMS devices which offers a low and stable modulus across the reflow profile. The material has no bleed and higher adhesion strength than previous-generation adhesives and is completely customizable. The unique...
