As consumer products become more compact, the challenges of materials joining become more complicated.
EWI provides you with resources to develop and implement the most efficient and reliable microjoining solutions for your applications — quickly and effectively.
For more than 30 years, EWI has been employing a broad array of joining techniques at the micro level. Our state-of-the-art labs contain equipment for every joining process used in electronic and medical device assembly, including ultrasonic and thermosonic bonders, micro-TIG welders, and precision resistance welders. Resistance reflow soldering equipment and controlled-atmosphere furnaces are also part of this lab.
Our deep expertise in welding technology, metallurgy, materials science, and process design enable our clients to develop comprehensive solutions for joining new products or increasing the efficiency of currently used manufacturing techniques.
Innovations
Over the years, EWI has resolved microjoining issues in applications such as lighting, medical and electronic device connections, miniature motors, automotive components, sensors, superconductors, and fiber optics. Some of our customer solutions have included the following:
- DEVELOPED PARALLEL-GAP RESISTANCE WELDING PROCESS for welding of 56 AWG copper wire to plated copper on polyimide flex circuit, to eliminate solder in an implantable medical device.
- ADVANCED NEW JOINING TECHNOLOGIES for assembly of 3D-printed components and flexible hybrid electronics.
- DESIGNED, BUILT, AND DEMONSTRATED FIXTURING for resistance welding drawn filled tube without exposing core material.
- DEVELOPED RESISTANCE WELDING OF NITINOL WIRES TO STAINLESS STEEL to eliminate a crimp joint and reduce component size.
- DESIGNED AND DEPLOYED A TIG WELDING SYSTEM for smoothing of wire ends for an ear-nose-throat surgical device.
- DEVELOPED A RESISTANCE WELDING PROCESS for replacement of solder joints on a communications satellite application, including mechanical and thermal shock testing.
- EVALUATED SEVERAL PB-FREE SOLDERS FOR SUITABILITY in a high-reliability electrical power transmission component.
