Testing Technology
Test Station
for vibration analysis of hard-disk drives
The vibrations emitted during the operation of a hard disk are measured
at a resolution of 20 nm using a laser vibrometer. The integrated computer
controls the entire test run and compiles an automatic measurement protocol.
Testing and Sorting Machines
for identification chips
The chips (or "STICKS") are inserted either manually or automatically
and are assigned to a measurement cell, tested by high-frequency signal
and sorted into three different classes, based on the test results, with
an SPC assuming control of the process.
Automatic Test Machine
for ABS sensors
ABS sensors are mounted on a carriage at 10 µm intervals and are
brought within working distance of the profile plate. The measurement
signals are thereby recorded, evaluated and automatically logged.
 
Automatic Sorting Machine
for IC chips
The magnetically identified chips are separated using a vibratory feeder
and conveyed, in the correct position, to a magnetic system for sorting.
The throughput rate is approx. 100,000 an hour.
Automatic Test Machine
for diodes
Fastened diodes are contacted and electrically tested during measurement
throughput. Unwanted components can then be punched out.

Bandwidth Measurements
with CCD camera and slit barrel
 |
The width, length and edge position of fast-running bands are precisely
measured and controlled. The operating program based on Windows NT allows
for integration in an automatic production control system. |
