I finally removed the sensor assemblies from my cameras, D70 and D40. Few notes:
- D70 was soooooo easy, it took less than 5 minutes to have the sensor out and the camera assembled again. Back off, sensor out, back on.
- D40 has a PCB behind the sensor and this needs to be removed. There is even a wire that needs to be desoldered. The removal is bottom off, back off, PCB off, sensor out, PCB back on, back back on, bottom back on. Similar to Canon 450D.
- The sensor metal frames are completely different for D70 and D40. So much for reusing the existing metal frames... it would limit the camera choice to one camera only.
- D40 has a flex PCB. It will be easier to desolder the sensor from it.
Photos attached. Sorry about the quality, I can retake if needed.
