Thermistor Production Test Using the B2900A Series of SMUs

PublishTime：2021-04-19

Thermistors are devices that exhibit variations in resistance as a function of temperature. Due to this property, thermistors are used for a variety of applications such as temperature sensors, current limiting devices and liquid level sensors.
To ensure compliance with manufacturing specifications, single-point pass/fail DC testing must be performed on thermistor devices. Because these tests are also used to identify and remove defective devices before shipment, their reliability is important to guarantee product quality. In addition, it is also essential to perform the tests quickly to keep the production throughput high. However, the thermistor's sensitivity to temperature changes can work against measurement accuracy since Joule self-heating during measurement can alter device characteristics. This requires measurement instrumentation used for thermistor characterization to possess both precise low-current resistance measurement capability and pulsed current measurement capability (to minimize self-heating effects).
The Keysight Technologies, Inc. B2901/02/11/12A Precision Source/Measure Unit meets all of these requirements, making it the best solution for thermistor production test. It is a compact and cost-effective bench-top Source/Measure Unit (SMU) with the capability to source and measure both voltage and current. They cover currents from 10 fA to 3 A (DC)/10.5 A (pulse) and voltages from 100 nV to 210 V. The B2900A Series of SMUs has the ability to perform not only DC measurements but also pulsed measurements in order to prevent device self-heating from distorting the measurement results. In addition to these comprehensive measurement capabilities, the B2900A Series of SMUs possesses high throughput that reduces test times. The B2900A Series of SMUs also has many features that make it well-adapted for production test, such as pass/fail binning, a digital I/O interface for handler control, and code compatibility with standard single channel SMU products.
This technical overview shows how to use the B2900A Series of SMUs for production test using a thermistor device as an example.
