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
Smartphones and Feature Phones

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.

Extreme Pressure Meets Ultimate Protection.
Posted November 27, 2018
People are taking their devices everywhere and through all conditions, subjecting them to temperature changes, rapid altitude and pressure shifts, compression of sensitive touchscreens and even immersion in liquids. Over time, this can put stress on housing seals allowing water and contaminants to enter device, and create pressure build-ups in acoustic cavities causing transducer bias, compromising acoustic quality and eventually damaging the transducer.
