Measurement instrument module compatible with mass production inspection of multilayer ceramic capacitors, which are becoming smaller and higher capacity, PCI Express compatible C meter board.
This product is a PCI Express bus-compliant C meter board capable of high-speed, high-precision measurement of capacitance (C) and loss coefficient (D). It features two channels of four-terminal measurement, allowing a single unit to incorporate the functionality of two benchtop measuring instruments into a Windows PC, contributing to the miniaturization and cost reduction of electronic component inspection systems. In recent years, the demand for multilayer ceramic capacitors (MLCCs) has increased against the backdrop of the proliferation of smart devices such as smartphones and the electrification of mobility, including automobiles. Additionally, these devices require miniaturization and extended battery life, leading to advancements in the miniaturization and high-capacity of MLCCs. The new product enables the measurement of capacitance (C) from 400pF to a maximum of 1400μF and energy loss coefficient (D), making it suitable for inspecting high-capacity MLCCs.

Applications/Examples of results
With the increase in the production volume of electronic components, measures such as implementing multiple inspection lines for inspection equipment are being taken. However, the challenges that arise during this process are the enlargement of the equipment and communication speed. When constructing a multi-line inspection system using conventional benchtop measuring instruments, many measuring devices need to be arranged in parallel, leading to an increase in the size of the inspection system. Additionally, communication between the measuring instruments and the PC for inspection result determination involves Ethernet, USB, and GPIB, which contributes to longer takt times. This product is an expansion board that transforms the C meter function, which has traditionally been dominated by benchtop measuring instruments, into a PCI Express-compatible format. It contributes to the miniaturization of the inspection system and reduces takt time through high-speed data processing that leverages the advantages of the high-speed local bus PCI Express.
