Debayered Sensor Received - build start

Today I received my now debayered 12.2 Megapixel sensor back from CentralDS. A really quick return trip of only four days from South Korea - way to go EMS.

It was returned disassembled because I asked for it that way, I did not want the original Canon cover glass reinstalled (it's too highly reflective compared to Mulitcoated alternatives), and I wanted to inspect the debayering job right to the edges and contacts. You can see in the photo that the chemical bayer matrix stripping does make a bit of mess on the edges but the pixels area is all clear and there are no scratches, stain, etc - I can tolerate the edge mess.
I also received the Astronomik MC Clear EOS Clip-in filter that I ordered to replace the Canon cover glass to create a sealed chamber in front of the sensor.
Now I can get to work on reassembling the sensor and installing the cold finger. The Anti-Alysing filter is still on the plastic filter frame but I will be removing that as well from the final assembly. The optic train will just be the MC Clear Clip-in to the sensor face.
I may cover the 'now' exposed contacts on the edge of the sensor to prevent any flaring off of those but I need to consider how I cover them up or even if, provided they are hidden by the sensor frame.
Photos attached.

BTW I will be putting a Teleskop-Express EOS Filter Drawer on the camera as well. Details here:

This filter drawer will maintain the focal distance of my current EOS T-Adaptor and allow changing of filters without removing the camera from the focuser, and provides adequate heatsink/fan clearance to allow access. It seems to be the only real option for this cooled camera. I have not ordered this unit yet, that will have to wait for after Christmas I think; I want to test the rebuilt 12.2 megapixel mono cooled camera in just luminance mode for the coming new moon period if I can get it ready in time. Looking forward to a big resolution improvement over the OSC sensor.
