[labnetwork] Polishing tool

[Zuzanna A. Lewicka]

Hello,
Here at PRISM Cleanroom facility, in packaging room, we have Logitech Lapping/Polishing system (https://prism-cleanroom.princeton.edu/instrument.php?iid=39) and handmade holder for die edge polishing (see attached picture). This setup was used once for polishing III-V edge emitting semiconductor lasers. Currently, in packaging laboratory, we also have new Loomis cleaving tool (https://prism-cleanroom.princeton.edu/instrument.php?iid=71 ). The cleaved facets have a quality of a mirror and do not need subsequent polishing.

Best regards,
Zuzanna

We have a low-cost polisher from Allied High Tech
http://www.alliedhightech.com/Equipment/metprep-1™-grinder-polisher
which is used to polish the ends of waveguides. Wafers are mounted on
either a wedge polishing or cross-sectioning jig (also from Allied High Tech).
It's best to put it next to a sink, in a dirty lab.

I suggest plugging it into a foot-pedal which acts as a dead-man's switch.
It's handy for stopping the wheel without taking your hands off the jig, and
it's a good safety device to reduce the risk of injury. It's a spinning wheel that
you'll want to supervise much like a band saw or a drill press. Keep some bandaids
nearby.

Hello,

I am looking into offering capabilities for polishing the edge of chips
to our users working on optical devices. If you have equipment in your
lab that does that, I hope you can share your experience and
recommendations with me or the network.

Thank you in advance for your help.

Best regards,

Iulian
