Major Japanese And Korean MLCC Manufacturers Order Multiple ESI 3510 Test Systems

Electro Scientific Industries, Inc. (NASDAQ:ESIO), a leading supplier of innovative laser-based manufacturing solutions for the microtechnology industry, announced the receipt of multiple-unit orders from leading Japanese and Korean electronic components manufacturers for ESI’s model 3510 test system. The customers will utilize ESI’s systems to expand production of the smallest geometry multi-layer ceramic capacitors (MLCCs) typically used in smart phone applications. Up to 500 MLCCs of size 0603 (.6mm x .3mm) and 0402 (.4mm x .2mm) can be integrated into a single smart phone. ESI’s unparalleled small device handling and extremely high throughput enable the 3510 to meet the customers’ demand for quality high-speed production testing.

ESI’s model 3510 performs electrical testing of the industry’s smallest MLCCs used primarily in smart consumer electronics. Its high speed design combined with reliable and repeatable sorting capability provide the industry’s best cost of ownership to ESI customers. Precision-controlled dynamic contact force eliminates marking on the MLCC’s metalized terminals so solderability to the circuit assembly is not compromised. The 3510’s high throughput is enabled by patented rotary technology that allows multiple tests to be performed simultaneously. It can test and sort up to 840,000 MLCC chips per hour, which provides a level of productivity that leads the industry.

Vernon Cooke, ESI passive components product marketing manager, noted, “The adoption of our 3510 system strengthens ESI’s position as the leading test equipment provider to the MLCC market. The 3510’s exceptional high speed processing capabilities of devices smaller than half a millimeter long with reliable and repeatable sorting enable productivity levels for our customers much greater than existing MLCC testers for very small devices."
