- Since 1995, PHP made a
huge effort investing in non destructive
inspection methods. This effort helped to
design a new automated ultrasonic
inspection device for internal
defect characterization within
ingots.
- The whole volume of ingot
production is inspected and each billet
is 100% inspected at a very high level of
detection. Results are stored in the
computerized system. A graphical image of
the inspection results can be delivered
to the customer on request..
- Additionally, a sampling of
production is regularly made for
inspection using a high frequency
ultrasonic inspection with a much
improved level of detection (between 30
and 300 microns), on slices adjacent to
the commercial ingot
- Having used such equipment, PHP
has achieved a significant improvement in
reducing internal defects in order to
reduce the arcing effects during
sputtering.
- GIGALLOYS are produced using patented processes : FR2744805, US5955673, US5887481, Taiwan 105486. Pending patents in Japan : 115242/96 and 9-529039
