Comments from the Judging Panel
This is a system for the final frequency adjustment
in the production of quartz crystals. Innovative features
include a "Direct Impedance Measurement Method"
which was proposed by the company and now accepted
as the de-facto standard in crystal measurement to
measure the frequency specification tolerance of crystal
accurately. Moreover, to further improve measurement
speed, a new iterative search algorithm which is developed
by the company to intelligently sample data in the
measurement phase during different stages of the plating
cycles. The non-linear vacuum deposition process stemmed
from the thermal capacity of the metal filament and
its electrical resistance together with the resulting
control loop is able to accommodate a much larger
dynamic range of filament types and much larger load
variation. It also features reliable mechanical and
electrical feed-throughs into the chambers for material
handling during the manufacturing cycles. As a result
the product is at a very competitive price while it
out-performs similar models from Japan and USA.
