Thunderline-Z, a supplier of feedthrus and hi-rel packages to the RF/microwave community, has announced the release of a new 1.2 square inch, 28 pin, surface-mount hi-rel package. Using an innovative bonding approach, Thunderline-Z was able to laser weld 9 mil mini Bell Pins into a Kovar housing, achieving pin spacing of 0.135 inches. The result is a rugged, ultra-small, high frequency surface-mount package that can withstand extreme temperature fluctuations over a long period of time. These packages are a smart alternative to soldered pins, and can be used in space and other hi-rel environments.
