A pioneering concept in immersion protection for mobile electronics

The new GORE® MEMS Protective Vents – Style 300

GORE MEMS Protective Vent Style 300

High-speed printed circuit board assembly may compromise the integrity of MEMS microphones. Damage and contamination cause yield loss, performance degradation, and higher production costs.

As mobile devices get smaller, installing traditional acoustic vents in shrinking acoustic channels becomes more technically difficult.

Our new GORE® MEMS Protective Vents - Style 300 not only prevents particle contamination and allows in-process testing, but eliminates the need for installing a separate acoustic vent on the device entirely.

This enables the first MEMS microphone with IP68 dust and immersion protection - a second option to device engineers to provide water ingress protection.



New GORE® MEMS Protective Vents - Style 300

The GORE® MEMS Protective Vents – Style 300 are installed inside the MEMS microphone during the microphone packaging process, providing component-level IP68 water and dust protection without any special handling during the circuit board assembly process. Parts are digitally mapped in a wafer format and are compatible with high-speed die attach equipment.

This pioneering venting solution eliminates the need for a separate acoustic vent installed on the housing, reducing complexity and saving space in the acoustic channel of water-protected devices with a IP68 rating for improved water and dust resistance. As consumers look for their mobile devices to do more, IP68 water resistant phone membranes bring improved protection with simpler implementation.

Using microphones protected by Gore’s IP rated vents, device OEMs can improve acoustic consistency, unlock operational efficiencies, and cut costs. Reliable particle protection also helps to prevent mic failure during the manufacturing process.
