MEMS protection membrane

MEMS is more and more widely used among electronics OEMs , who are desperate to find an integrated acoustic solution that maintain the integrity of MEMS microphones during the high-volume assembly of printed circuit boards for smartphones, smartwatches, earbuds and other consumer devices.

MicroVent® MEMS Protective Vents is rated IP68, offering component-level water and dust ingress protection, eliminating the need for installing separate water protected acoustic vents on the device entirely.

MicroVent® MEMS Protective Vents have been stringently tested and proven to prevent particle contamination and pressure build-ups. Our vents also allow in-process acoustic testing and integrate seamlessly into automated dispensing and placement processes.

MicroVent® has been studying and developing expanded polytetrafluoroethylene (ePTFE ) membranes over 30 years. MicroVent® Acoustic ePTFE has a unique microporous structure. It is comprised of small randomly connected fibrils that render an effective pore size many times. MicroVent® membrane microporous films are naturally hydrophobic and can be used as permeable water and oil barriers.

MicroVent® Acoustic Vents deliver consistently exceptional sound transmission and clarity, ensuring seamless voice calls and flawless audio experiences. All of MicroVent® Acoustic Vents will be tested strictly before leaving the factory to ensure your devices remain shielded from dust, water, and other damaging elements.
