The 2008 Aerospace/Defense Symposium papers are now available free on CD. The fifteen technical papers reflect two tracks: test system development and military communications test. Also included is information on wideband vector analyzer calibration issues and time interval analysis measurements for radar.
The DispenseJet DJ-9500 fluid jetting valve is for high-speed underfill applications and jetting silicone for LEDs. Has a flexible pneumatic design. Reportedly can jet a wide variety of fluids up to 10 times faster than existing needle type dispensers. Controls fluid break-off at the nozzle tip. The needle assembly is said to last 5 to 10 times longer than other tested assemblies. Enhanced temperature controls maintain the fluid at a consistent viscosity.
ZIP contacts for semiconductor test feature planar contact surfaces produced by test pin manufacturing processes. The Z Interconnect Pin is available in three design configurations: radial, flat, and hybrid. Radial uses machined 3-D components; flat employs 2-D components, and hybrid combines both. Are designed for interchangeability in the same test tool. Available for 0.5, 0.8, and 1.0 mm test pitches with 1.27, 0.4, and 0.3 mm designs.
