EWI Improves In-House High-Magnification Measuring Capabilities

Designers at EWI often need to take precise measurements of extremely small parts. Measurement of small parts using calipers has two problems: Errors associated with measurements using traditional calipers become significant on a small scale The pliable nature of small parts makes them susceptible to distortion when measured with calipers, which yields inaccurate results A […]

Ultrasonic soldering for medical and other electronic devices

Ultrasonic soldering a variant of traditional iron soldering, where instead of requiring a flux to chemically reduce the metals’ surface oxides, the ultrasonic vibration from the soldering iron produces cavitation bubbles in the liquid solder.   When the cavitation bubbles collapse, the mechanical motion of the collapse abrasively removes the surface oxides from the metal to […]

When most people hear the word “welding” they think of the guy in the local garage with an arc welder and a mask, or the army of spot welding robots used to build a car body.  You might be surprised to learn that there are many more welds in the sensors and motors in a […]
