The RapiTrim workstation
enables the realization of full production for embedded passive trim and
test. Through the use of proprietary fixtureless technology, probe
cards and their inherent limitations are eliminated. Restrictions on
design layout have been lifted, and operational delays waiting for probe
cards have been removed.

RapiTrimä
is a breakthrough new concept in production workstations for embedded
passive and hybrid trim and test. Users experience all the benefits of a
fixtureless system without the sacrifice of slow trimming speed. Circuit
designers are no longer limited by the practical size limit on probe card
designs; circuits can be as large as the panel itself. Each of the four
probes as well as the galvanometer-located laser beam have access to the
whole 50x50mm field, ensuring that any component location, size,
orientation and component density can be accommodated. Probe fields are
tiled together using the high accuracy XY stages. The small field size
allows the use of a smaller, lighter probe positioning mechanism, leading
to rapid, accurate probe tip movement.
In addition, the system
can function as a stand-alone tester, with the trimming function turned
off.
