A must for PCB debugging and testing

Canadian Siborg Systems Inc. and Brazilian, San Paulo based Unicoba have agreed to jointly market Smart Tweezers LCR-meter and LCR-Reader in South America.

Unicoba offers customers a wide range of services including Advanced Technology in Electronic Manufacturing, Logistics and Sales Distribution through various business channels, Installation, Maintenance and Post-sales Services. It covers Telecommunication, infrastructure, Energy, IT, Security and Industrial sectors.

"Increasing use of Printed Circuit Boards (PCBs) with a high density of Surface Mount Devices (SMD)," says Michael Obrecht, Director at Siborg Systems Inc. "Stipulates the use of Smart Tweezers LCR-meter which is an indispensable tool for PCB repair. Unicoba is a large supplier of various electronic gadgets and equipment with offices all around Brazil. This makes them a very important representative in a quickly expanding Brazilian economy."

LCR-Reader, the successor of Smart Tweezers LCR-meter ST-5, was designed for measuring small SMT components that can be about 0.3 mm. Smart Tweezers measure in addition to the capacitance, equivalent series resistance of a capacitor, or parasitic resistance of an inductor. It also can be used for a continuity and diode test.

The new model, LCR-Reader, is lighter than the previous Smart Tweezers models, it is powered by Li-Ion rechargeable battery with a micro-USB connector port. Basic accuracy of the new device is about 1%. It has a simplified one button control turning the device on and changing the operation mode by a single button push.

On a picture to the right is a screen showing measurement of an inductance, where AM shows that the measurement mode is Automatic Mode, Rs specifies parasitic series resistance of the inductor, 10 kHz is the test frequency, L shows that the component measured is an inductance, 104.8 uH is the inductance in micro-Henrys, and the battery sign indicates the battery charge level.

Compared to ST-5 the following features are not available: automatic offset correction, component sorting, diode and continuity test. The most important drawback of LCR-Reader is the level of test signal which is 0.5 V rms that does not allow to use it for ceramic capacitors, similarly to ST-1, ST-2 and ST-3 it gives a lower value of the capacitance.

A comparison of features of the LCR-Reader and previous models is presented in this Smart Tweezers Comparison Table.

Feature Summary
Automatic measurement of Inductance, Capacitance, Resistance and ESR
Basic accuracy of 1%
Automatic selection of the best range
Lithium-Ion battery and USB charger connection port
Weight of 28 gramms (1 oz)
