Actually Fetter, there is a reference to a Hybrid-Tek order from CERN, but that goes all the way back to 1999 before Hybrid-Tek was acquired by Cetek in 2005. Here's the paragraph:

K K Gan (Ohio State)

Work is continuing on the design and fabrication of a prototype optical package. The procedure for depositing Au/Cr traces on the bases has been systematically investigated. We find that a minimum of ~1 micrometer of Au over ~0.1 micrometer of Cr is needed for wire bonding because the surface of macor is uneven at 10 micrometer level. This requires a long deposition time and hence we decided to explore the alternative procedure of screening on the Au. We have placed an order with Hybrid-Tek for depositing 12 micrometer of Au on up to 8 macor rods (9 bases/rod) and expect the delivery in about 3 weeks.


The VCSEL is supposed to be attached to the Au trace on the base using the surface mount technology. Several attachment attempts were not successful. We believe that this is due to the lightweight (0.007 microgram) of the VCSEL, resulting in little physical contact between the Au/Sn layer on the bottom of the VCSEL and the Au trace. A small pressure must be applied on the VCSEL. Two different jigs for applying the pressure were fabricated. One uses two small custom-made needles and the other uses two small custom-made brass chips with the same dimension as the VCSEL. Both techniques failed. We are currently investigating the possibility of tinning the gold traces to even out the surface and provide more contact between the VCSEL and the trace.
