ESI introduces laser based module for advanced microprocessing

An advanced laser microfabication system is introduced by ESI.

PORTLAND, Ore. - Electro Scientific Industries, Inc. (NASDAQ: ESIO), a leading supplier of innovative laser-based manufacturing solutions for the microtechnology industry, today announced the release of its new esiFIT technology for advanced microfabrication. The esiFIT module is designed to enhance the micromachining capability of ESI’s 5900 systems. The model 5900 equipped with esiFIT technology becomes a laser-based processing tool that performs in-line inspection of incoming parts and subsequently adjusts the laser cutting path in “real time.” This technology can be applied to a number of micromachining applications such as the tailoring of tolerances between two manufactured components, preferential removal of material on “out of spec” parts, and bur removal applications, among others.

The 59xx family of laser micromachining tools offers customers a broad range of features to control cutting shape, throughput, and laser-material interaction. Additionally, the esiFIT option enables automatic inspection of incoming parts, recognizes anomalies in the presented piece, and then adjusts the machining path to compensate for the identified anomalies. The ability to automatically compensate for the machining path based upon incoming part variation enables customers to increase their yield, reduce rework, and create custom fit parts. ESI has over 300 59XX systems deployed in 24/7 high volume manufacturing lines worldwide used for laser-based microfabrication processes.

“High-precision microfabrication is an important part of numerous industries including consumer electronics, automotive, and medical,” said Dr. Michael Darwin, Vice President and General Manager of ESI’s Interconnect and Micromachining Division.

ESI systems enable precise structuring and testing of micron to submicron features in electronic devices, semiconductors, LEDs and other high-value components. They partner with customers to make breakthrough technologies possible in the microelectronics, semiconductor and other emerging industries. ESI is headquartered in Portland, Ore., with global operations from the Pacific Northwest to the Pacific Rim. More information is available at
