Smart Tweezers and LCR-Reader Verification Tool Released for Distributors from Siborg Systems Inc. and Institute of Automation and Electrometry of the Russian Academy of Sciences

Siborg Systems Inc., in Waterloo, Ontario, and the Institute of Automation and Electrometry of the Russian Academy of Sciences, in Novosibirsk, Russia, have designed together a verification jig that uses known components to test and verify Smart Tweezers and LCR-Readers’ performance and accuracy. The jig is able to verify all models of Smart Tweezers from the ST-3 to the ST-5 and LCR-Reader, using 16 known components.

Smart Tweezers LCR-meter and the newer LCR-Reader are a handheld alternative to conventional bench type testers for evaluating Surface Mount Technology (SMT). Manufacturing electronics uses SMT, small components that are mounted directly onto a Printed Circuit Board (PCB). These small components are generally unlabelled due to size, and may be difficult to keep track of the values, Smart Tweezers was designed specifically to combat these problems. The unique design of Smart Tweezers LCR-meters combines a set of tweezers with a LCR-meter in a handheld unit, that requires only one hand to operate and no set-up between evaluations. Instead of long wire leads and two hands, a component only needs to be “pinched” with Smart Tweezers in order to determine the type of component and proper range and signal frequency for high accuracy evaluations. The results, component type and test conditions are instantly available on the OLED display embedded in the handle.

“Although all Smart Tweezers PCBs are calibrated after the PCB is made, verification jig is still a desirable tool for incoming control and troubleshooting devices returned due to a failure or malfunction. It can also be used for periodical traceable calibration if the jig is calibrated by a certified agency. The best thing about the jig is that it can be used for any model of Smart Tweezers after ST-3 where the 4-wire connection was first used.” says Michael Obrecht, the Director of Research and Development at Siborg Systems Inc.

The jig uses a set of 16 known components; 8 resistors, 4 capacitors and 4 inductors of different values in the measurement range that Smart Tweezer is able to measure. The ST device is connected to the jig using a 4-wire connection. This 4-wire connection is essential in order to reduce the noise generated by the connections on the PCB. The connections are controlled by a microprocessor and a set of 32 relays. Between measurements, the micro-controller goes into sleep mode in order to reduce the effect or the digital circuitry on the measurement. When a button on the jig is pressed, it connects to each component in sequence with the results appearing on the display, with detailed information about the devices’ performance.
