GORE® MEMS Membranes for Sensors
Our customizable membranes and adhesives accelerate higher-accuracy, higher-reliability open port MEMS sensors while increasing manufacturing efficiency and yields.
More Reliable MEMS Sensors. Higher Yields. Faster Market Entry.
Our tailored membranes and adhesives help OEMs speed up the development of open-port MEMS sensors with enhanced accuracy and reliability, while also supporting OSAT companies in boosting manufacturing efficiency and output. Throughout every stage, from development and installation to handling and operation, our global membrane team provides fast rapid sampling and expert technical expertise.
Protective Membranes for MEMS Open-Port Sensors
Designed for gas, pressure, and humidity sensing applications, our protective membranes enable stable sensor operation, reduce contamination risks and improve long-term durability.
Particle Shielding
Increase yields and control costs with reliable particle and contamination protection in SMT process and during end-use.
Ingress Protection
Enable ingress protection up to IP68 lifetime component-level protection, depending upon materials set.
Superior Gas Diffusion
Maintain fast and reliable sensor response time with consistent, high-quality membranes in compact designs.
Excellent Reflow Capability
Stand up to high temperature soldering (according to JEDEC) without compromising material integrity or sensor function.
Manufacturing efficiency
Supports high-volume production with seamless integration and proven durability by offering different product forms.
Advanced Membranes for MEMS Open-Port Sensor Applications
Our membranes are engineered for easy integration into a range of MEMS open-port sensors including:
- Gas sensors
- Humidity sensors
- Pressure Sensors
