IC Programmer & Laser Mark
Handler. Chip programming applications. This is a system to automatically
program and laser mark a variety of programmable IC's. It was developed
primarily to handle fine-pitch packages using a precision pick and place
approach. There are two independent Z axis suction cups on the gantry, and each
also has a socket opening mechanism. Two heads are used to enable very quick
device swapping by pick up of an existing chip, then immediate placement of a
new chip. Use Jedec trays or tubes. Anybody's programmer can be utilized, and
the most common are already integrated. The laser will mark any size part with
any data or graphic.
PGA
Hermetic Leak Test Handler. Semiconductor industry. Fully automated test
system involves the operation of 3 sealable and heated test cells that sniff for
residual chlorofluorocarbon fluid of pin grid array (PGA) semiconductor packages
(hermetic leak test techniques), then correlates measured values to hermeticity
leakage. Automation accepts continuously fed top stacked Jedec trays full of
PGAs and loads each into the machine. A high-speed pick and place unit
vacuum-picks four PGAs at a time and places them into a test cell, closes the
cell and begins the heating, vacuum and sniff test sequence. Class 100 clean
room compatibility, anti-static materials and attention to smoothed motion
parameters allows full production of 80486 chips through this machine. System
sorts completed PGAs back into trays. Prototype system also developed.
