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, smartwatches, earbuds and other consumer devices.
Working directly with OEMs, microphone manufacturers and contract manufacturers, Gore has developed unique venting products proven to provide microphone protection by preventing particle contamination and pressure build-ups, and allowing in-process acoustic testing. Reliable particle protection also helps to prevent mic failure during the manufacturing process.
Additionally, as devices get smaller, installing traditional vents in the ever-shrinking acoustic channels of mobile electronics becomes more challenging.
Our latest venting solution, the GORE® MEMS Protective Vents – Style 300, 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.
With our advanced materials technology, device OEMs can improve acoustic consistency, unlock operational efficiencies, and cut costs.
Applications
GORE® MEMS Protective Vents are available in three 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 particle contamination (Style 100, 200 & 300) or even water immersion (Style 300 only). The expanded PTFE membrane also prevents pressure build-ups that may cause damage to the microphone.
GORE® 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. The GORE® MEMS Protective Vents - Style 300 provides IP68 water protection for microphones.
