High Volume Test of environmental Sensors

17 August 2016 - Multitest’s first InHumid test system for final test of environmental sensors was successfully installed at a major European IDM. The Multitest solution allows for high volume single-insertion test and calibration of integrated environmental sensors measuring pressure, temperature, humidity and gas.

InHumid is an optional upgrade to Multitest’s well-established InBaro module, adding humidity and gas test to the barometric test capability provided by InBaro. The physical structures to apply humid air or gas flow to the DUT reside inside the conversion kit. This architecture facilitates easy upgrading in the field. For testing the gas element of environmental sensors InHumid can be extended by a gas option. This option provides the measures needed to operate the machine in a safe manner when testing typical environmental, gases traced in air quality monitoring, or personal fitness applications (e.g. connections to attach to a general exhaust system).

The InHumid solution fully leverages the temperature capabilities and proven high volume performance of the InBaro/InStrip set-up. Like with InBaro InHumid can be used in a Multitest InCarrier set up to support reliable and robust test handling of small MEMS packages, which are typical for environmental sensors in consumer applications.

Gabriela Born, Director InMEMS and IoT Products, comments: “Our customers are experiencing a growing demand for environmental sensors mainly driven by expanding applications on consumer devices. In particular gas sensors in smartphones and wearables are expected to raise the number of shipped units exponentially over the next 4 to 5 years. To meet this demand, true high-volume production solutions will be necessary, which provide reliable test at low cost per unit.”
