Product Application : MEMS Pressure Vent


MEMS sensors are usually exposed to harsh conditions, such as rain, dust, gases, and chemical liquids. On the one hand, MEMS sensor chips need to collect accurate measurement data through direct contact with external environment as much as possible. On the other hand, the chips should avoid erosion by rain, dust, or other pollutants to maintain good working condition.


The effective air permeability of IPRO MEMS pressure vent can reach up to 2000-25000ml/min/cm², which not only blocks the erosion of pollutants, but also ensures the normal operation of MEMS sensors.


In addition, the heat resistant ePTFE membrane can be used for reflow soldering, both in SMT process and surface mounting.
