High density embedded capacitance materials are halogen-free

3M has announced the availability of its high-capacitance Embedded Capacitance Material (ECM), which improves power integrity and reduce electromagnetic interference (EMI). The newest offering of 3M’s ECM material will provide one of the highest capacitance density and halogen-free solutions on the market. This helps design engineers provide hi-fidelity signals, high-signal-to-noise ratio in radio frequencies and higher speed digital signals in a variety of high-performance applications such as small form factor computer hardware, high-performance RF boards, microphones, integrated circuit (IC) packaging, and consumer electronics.

The 3M ECM High-Capacitance Density solutions offer a capacitance density range from 20nF up to 40nF per square inch. With the increase in capacitance density, design engineers can now use the offerings to drive high-frequency noise reduction to levels that could not be achieved with current generation solutions.

“As electronic devices continue to see drastic miniaturization, while requiring increased fidelity, 3M is constantly looking for innovative solutions to help drive this market trend,” said Abhay Joshi, global business development manager, 3M Electronic Solutions Division, Interconnect Business. “Our newest line of Embedded Capacitance Material provides the industry with one of the highest amounts of capacitance per square inch, giving design engineers an additional tool in their arsenal to achieve their design goals.”

3M’s line of ECM material offerings can be embedded into printed circuit boards (PCBs) and integrated circuit chip packages where the applications include decoupling and low-pass filtering. With a high-capacitance density offering, the functionality of ECM material can now be ideally leveraged for microphone makers in the miniaturization of their products, along with a significant reduction of RFI on the devices. Fabricators and OEMs worldwide may use 3M’s ECM material without purchasing a license from 3M. The material is RoHS compliant.
