[Hbi-svt] Fwd: PA_JLab_v4.gds

[Brian Eng]

Attached (in 3 different files) is what I hope to be the final design of the pitch adapter. Unless any new issues are brought up, I'm hoping to send approval of the mask by noon tomorrow.

The files are the following:
-- Original mask file in GDS format.
-- The mask file converted to AutoCAD 2007 DWG format.
-- A mockup of the top of a module (top hybrid of HFCB, PA + H sensor) in the same DWG format.

Again, unless we want to be waiting until September for the order, speak now with changes or forever hold your peace.

Please review the design and tell me something by (my) tomorrow because otherwise I will not be able to submit the mask for fabrication until beginning of September.
