GORE® MEMS Protective Vents for Microphones
GORE® MEMS Protective Vents provide environmental protection and manufacturing efficiency while enabling in-process acoustic testing in the high-volume assembly of printed circuit boards.
Proven MEMS Microphone Environmental Protection
Gore’s unique venting products for microelectronics mechanical systems (MEMS) offer proven microphone protection by preventing particle contamination and pressure build-ups and allowing in-process acoustic testing, which helps prevent microphone failure during the manufacturing process. With our advanced materials technology, device OEMs can improve acoustic consistency, unlock operational efficiencies, and cut costs.
Environmental Protection
Particle Shielding
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.
Immersion Protection*
An integrated design installed at the MEMS mic package enables component-level IP68-rated water immersion protection.

Manufacturing Efficiency
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.
Pressure Equalization
Gore’s experience in providing vents with excellent airflow has been applied to the GORE MEMS Protective Vents. The breathable membrane of the vent allows gases to pass through the microphone port to mitigate pressure build-ups that may cause damage to the microphone.
Seamless Integration
Leading OEMs and their supply chains have protected over 1.5 billion microphones with 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.
Our range of MEMs protective venting solutions are designed to meet the specific needs of both circuit board assembly and microphone manufacturers for smartphones, smartwatches, earbuds and other consumer devices.
