Can you be competitive without the latest-generation high-speed MLCC testing solution?

High-Volume Testing of Multi-Layer Ceramic Capacitors (MLCCs).

Allegro is designed to help MLCC manufacturers meet the challenges associated with high-volume testing of even the smallest-size MLCCs. With its high-throughput testing capabilities, Allegro enables manufacturers to verify quality and ensure accurate specifications for the MLCCs used in the myriad electronic components and devices produced today.

Allegro has the flexibility to process even the smallest-size chip sizes—down to 01005 (0402 metric)—while testing performance in a range from <1pF to 100µF. It incorporates the automated eight-track testing capability pioneered by ESI, which means Allegro can process chips at speeds up to 20,000 per minute, while its advanced low-impact rotary handling technology—also pioneered by ESI—minimizes the potential for damage to the chips as the result of testing. This combination allows for consistently high throughput and higher testing yield.
