The fabrication data for the hybrids is in Gerber format. You will need
a computer with Gerber viewer software. If you have a pc running
Microsoft Windows, you may obtain a free copy of the
Lavenir ViewMate Gerber viewer.
Once you have ViewMate installed, you will need the data. A zip file
containing all the data, where each file is a separate layer, can be
downloaded by holding down the SHIFT key and clicking
**IMPORTANT NOTE** For some reason Viewmate does not want to import
these Gerber files without a fight. In order to successfully import them,
choose "options" from the import file dialog box and set the number of
digits to the right and left of the decimal point to 1 and 5 repectively.
This will also fix the scale of the drawing so that the units of distance
are mils, rather than 1/100 mils.
Some data files of interest are:
(1) W016.apt. This is a Gerber aperture file.
It can be imported into ViewMate at the start of a session to automatically
declare the necessary Gerber apertures. If you don't know what this means
don't worry, just use "import" "apertures" in the FILE menu to load
W016.APT when you begin a session (you'll need to guess type).
File A016.env instead of W016.APT will also work.
(2) A016Q and A016R. These are the two files that compose the top
metal layer of the hybrids. They contain all the component and cable
bonding pads. Use "import" "gerber" to load them.
A016N. This file contains the "top metal 5" trace layer. This has the
jumper bonding pads. Load with "import" "gerber".
A016L. This is the "top metal 4" traces. It contains the svx3 chip
bonding pads. Load with "import" "gerber".
A016X, A016Y, A016Z. These files define the openings in the top
3 (tape) dielectric layers. Load with "import" "gerber".
