GORE® MEMS Protective Vents
Gore, the world leader in understanding expanded polytetrafluoroethylene (ePTFE) and its capabilities, has engineered the world’s first vent proven to provide protection for MEMS microphones. GORE® MEMS Protective Vents guard against particle contamination and pressure build-ups while enabling in-process acoustic testing in the high-volume assembly of printed circuit boards.

Overview
There are several technical issues that can jeopardize the integrity of MEMS microphones during the high-volume assembly of printed circuit boards for smartphones, action cameras and other consumer devices.
Working directly with OEMs, microphone manufacturers and contract manufacturers, Gore has developed a unique solution–GORE® MEMS Protective Vents–proven to prevent particle contamination and pressure build-ups, and allow in-process acoustic testing.
Applications
GORE® MEMS Protective Vents are available in two formats designed to meet the specific needs of both circuit board assembly and microphone manufacturers. They are ready to handle the extreme stresses of high-volume, high-speed installation, as well as multiple reflow cycles of up to 280 ºC (390ºF) for 40 seconds.
Wherever MEMS microphones are used, GORE® MEMS Protective Vents can protect the microphone from damage by particle contamination

Audio Headsets
Smart Home Devices
GORE® MEMS Protective Vents have been stringently tested and proven to prevent particle contamination and pressure build-ups. They allow in-process acoustic testing and integrate seamlessly into automated dispensing and placement processes.
Particle Protection
GORE® MEMS Protective Vents are unique in that they provide reliable particle protection designed to reduce contaminants — helping to secure the SMT process, and helping manufacturers increase yields and reliably control manufacturing costs.
Pressure Equalization
Gore's experience in providing vents with excellent airflow has been applied to the GORE® MEMS Protective Vents. Thanks to the breathable ePTFE membrane of the vent, it allows gases to pass through the microphone port to mitigate pressure build-ups that may cause damage to the microphone.
In-Process Testing
Gore has developed a technology that both enables in-process testing of acoustic performance and improves process efficiency, by allowing manufacturers to monitor sound quality and permeability within the device and alleviating the need to assign resources further down the production line for re-testing.
Seamless Integration
Working directly with OEMs, microphone manufacturers, and contract manufacturers, Gore has manufactured over 100 million GORE® MEMS Protective Vents designed to handle the intense rigor of high-volume, high-speed installation, as well as multiple reflow cycles of up to 280°C for 40 seconds.

Recent News
While smartphones OEMS introduce models with higher resolution cameras or faster processors, our data suggests consumers would buy more phones if the OEM added water resistance.
Featured Story
As smartphones become more powerful and more expensive, consumers are holding onto their phones longer.
Posted May 18, 2020
Most consumers (75%) believe smartphone manufacturers should make all their smartphones water resistant (strongly agree 38%, somewhat agree 37%) The survey also found an emotional connection between the phone brand and water protection.
Featured Story
As smartphone usage increases, consumer attitudes are changing to demand more protection.
Posted May 11, 2020
Gore research shows that water incidents with smartphones is common (42% in the last year) and when incidents occur most consumers (81%) have a bad outcome (35% malfunction, 46% inoperable). This translates to 34% of households having a negative experience with their smartphones in the last year and 19% having to replace their smartphone.
