GreenSource Fabrication Enhances Testing Capability with MicroCraft

Reading time ( words)

MicroCraft installed an EMMA E4M6151 tester earlier this year at GreenSource’s state-of-the-art facility in New Hampshire. This E4M6151 is a very capable flying probe tester able to reliably test at high speeds while maintaining accuracy and precision. It is MicroCraft’s most popular tester model.

Michael Gleason, Director of Product Development, adds, “We are very pleased with the recently installed EMMA tester.  The majority of our products are multi-lam and build-up designs which require electrical testing of the sub-composites.  For panel level testing, EMMA’s speed, accuracy and reliability is industry leading and has opened up needed capacity in our ET department.  Its fine feature testing capability is a welcomed bonus.”

About GreenSource Fabrication

Today over 90% of PCB’s are considered commodities. To compete in the space where this statement is not applicable requires developing engineered solutions and technical differentiators. It demands an engineering driven company with a commitment to invest in state-of-the-art equipment, highly qualified personnel, and development of leading-edge practices. GreenSource Fabrication made the decision to invest in both equipment and talent. GreenSource Fabrication is a premier US based world class source of high-end PCB’s and substrates.
