Description

using andon socket for now

1-2mm through hole in PCB

cover entire top surface and around the sensor

try adding fins to front side

we cut away the andon socket sides to let the metal part behind the sensor

are you talking about cutting the andon socket like this? (hatched area)

how thick is that andon socket? in other words, how much space do we have (in mm) between bottom surface of the cmv12000 and top surface of the sensor board? i found the socket over here: Page 22, FIG.59

i'm still not sure about its height though.

correct!

2.82mm is the length of the andon pins

I commited a preliminary CAD model of the sensor cooler here: https://github.com/apertus-open-source-cinema/beta-hardware/blob/master/Enclosure/Version%20002/SensorCooler01.ipt
not checked or verified yet, so please take a critical look at it :)

ok, does that mean the socket height is 2.82mm as well?
i made a quick drawing. let me know if i got it wrong.

i don't have inventor at my workplace but i converted your ipt file with solid edge and made some measurements. mabye a conversion problem but see here: https://eveninfinite.com/downloads/axiom/SensorCooler01.ipt_preliminary.pdf
the distance in between the cooling fins is 45mm. the sensor width is 47 +-0.47 mm.
Houston we have a problem! the sensor won't fit in there. There is only one solution to fix this! We have to cut the sensor on both sides to make it fit! lol

i also took herby's eagly file (axiom_beta_sensor_cmv12000_v0.13.brd) to get some more dimensions and made another drawing. i'm unclear about the colored measurements but it might be another conversion error.
just to make sure pls recheck @Bertl https://eveninfinite.com/downloads/axiom/sensor_board.pdf

last but not least.. here is what i came up with after tinkering with your design. it's big and unfinished as well but before i go on i wanna make sure these numbers are correct =)

do you guys already have a tdp value of the sensor at max load? :)

i found another bug in the F-mount to CMV12k-V05.ipt
basicly everything that is marked lightblue needs to be moved on the x axis because the mount is not perfectly centered on the sensor when assembled.
see here: https://eveninfinite.com/downloads/axiom/f-mount/f-mount_correction.png and here https://eveninfinite.com/downloads/axiom/f-mount/f-mount_wrong.png

i have already corrected it and uploaded it to my server. i'm not sure if you are able to open sldprt (solidworks) files in inventor but lets try.
here it is: https://eveninfinite.com/downloads/axiom/f-mount/F-mount%20to%20CMV12k-V06.SLDPRT

the sensor is perfectly centered now: https://eveninfinite.com/downloads/axiom/f-mount/f-mount_fixed.png
here's another pic from the backside of the skeleton assembly.

There are aluminium cooling profiles out there. We should find a fitting profile to reduce production costs. Let's search...

maybe we can use the inner surface of the aluminium case to do some cooling (heatsync).
What about aluminium core PCBs?
