The high resistance meter SM7810 is a tester used to check leakage current in the production process of MLCC (Multi Layer Ceramic Capacitor). It can achieve high-speed measurement of up to 6.8ms and simultaneous measurement of 8ch.

The power unit SM7860 is a dedicated power supply for multi-channel systems, capable of outputting up to 32ch through dual system voltage settings of 8ch or 16ch units.

The inspection system combining SM7810 and SM7860 is most suitable for automated units, providing the fastest MLCC leakage current inspection production line.

The most suitable inspection system for measuring MLCC leakage current

Characteristics of SM7810+SM7860 MLCC Inspection System

The high resistance meter SM7810 has the ability to measure MLCC leakage current in 8 hours simultaneously, with a maximum speed of 6.8ms, reducing the intermittent time of automated units and achieving cost reduction of MLCC.

By combining the high resistance meter SM7810 with the power supply unit SM7860, the most suitable inspection system for automatic units can be achieved. By selecting the maximum applied voltage and function of the power unit, it can correspond to various inspection production lines including charging and discharging.

■HIOKI daily SM7810 high resistance meterProduct Features

The leakage current measurement of MLCC is as fast as 6.8ms for high-speed measurement, and 8ch for simultaneous measurement

● High speed detection of leakage current in large capacity MLCC with a large current range (1mA)

● Improve measurement reliability through contact inspection function

Each ch can be set separately, with flexible components for each system

Improved application performance

●Measurement time 6.8ms (from triggering to INDEX output)

Even when conducting contact checks and judgments, the measurement can still be completed in 6.8ms. (When measuring speed FAST)

The measurement time has been reduced by 30% compared to previous products, and the machine's downtime has also been shortened.

Each ch can be set separately

The range, measurement voltage, and comparator can all be set separately for each ch. Combining the system to build 8ch × 1 test bench, 4ch × 2 test bench, 2ch × 4 test bench, etc., can measure simultaneously and flexibly correspond to various automatic units.

Improved reliability

● Improve reliability through contact inspection function

Simultaneously complete contact inspection during high-speed measurement. To avoid misjudgment caused by poor contact of the probe and improve the reliability of the inspection.

■High speed leakage current measurement of MLCC (Multi layer Ceramic Capacitor)

Capable of measuring the leakage current of high-capacity MLCC at high speed.

Due to the simultaneous measurement of 8 channels, the performance of the automaton was improved by increasing the number of checks at once.
·By applying a measurement voltage of up to 1kV, even high-voltage ceramic capacitors assembled on EV frequency converters can be checked accordingly.
·By expanding the measurement range of current, it is also possible to measure the leakage current of capacitors during the charging process.
·By using the contact check function, it is possible to start measuring only after confirming good contact between the measured object and the measuring instrument.

The SM7860S power supply can output a voltage of ± 1V to 1kV, and also has a discharge function, so it can be used in conjunction with MLCC for inspection systems.
● Current limits can be independently set in each channel, so that even if one capacitor experiences a problem while measuring other capacitors, it will not be affected.
