Files associated with a proposal to mount opto chips on the forward hybrids with the PIN diode and VECSEL optical components mounted in a separate electrically pluggable package.
This has been studied as a response to the perceived difficulties of service routing, mounting and connecting modules on forward wheels using the original concept of chips and opto components mounted on separate kapton cables.

To understand use of layer names see pltabc1a.mac, this is a text format macro file used for producing plots from the PCAD database and contains all the layer names, their use in the database and the groupings of layers for plot production There are many layers in the database other than those used for plot production, containing mechanical info, layer buildup etc. Please understand that this database file has evolved over time and several different pcb and hybrid designs so it contains information on some layers that may not be up to date or relevant.

NEXT FORWARD HYBRID _ PROVISIONAL PLOTS FOR DISCUSSION
original and proposed increased cooling contact area on forward hybrids.
NOTE that the new increased area is close to the maximum possible using the original V1 hybrid profile. This has been achieved by removing all diagnostic lines and removing the bus and resistors required for distribution of the CAFE current setting line. If these are required then this new contact area will have to be reduced.
