High-throughput electrical testing of multi-layer ceramic capacitors (MLCC).

Model 3500A High Capacitance MLCC Tester

The Model 3500A performs high throughput production electrical testing of multi-layer ceramic capacitors (MLCC). The 3500A is designed to meet the set of challenges faced by MLCC manufacturers. With its high production throughput and flexibility, the 3500A allows customers to verify quality and ensure accurate specifications for MLCCs used in a variety of applications, in the manufacture of high-quality printed circuit boards used in nearly every type of electronic device. Although the 3500A can process up to 15,000 chips per minute, ESI’s advanced rotary handling technology minimizes the potential for damage to the chips as the result of testing is minimized, thus increasing yield.

The 3500A has the flexibility to test MLCCs from <1pF to 100µF, and provides process flexibility and maximum utilization to lower testing costs. Multiple tests are simultaneously performed on chips as small as 01005 (0402 metric) on using ESI’s patented rotary handler technology for continuous automation and reliable productivity.
