The display connector to cheap calculators can be source of conducting paint, just heat it with the soldering iron. Bond wires are welded on an eg. aluminum pads, so maybe unsolderable. Silverpaint could by an alternative. At the laboratories of my university there are several manual bonding machines. Maybe there is something similar near you.

Apropos, does anyone have a 1000d body left over? My sensor didn’t die, but now I can only swap between the original and the debayered sensor for one body. Despite the sensor all parts should be in a working conditio. I made a picture of the moon but the resolution of my MTO-11CA (f=1000mm Ø=100mm) is not high enough to see a positive effect in removing the Bayer layer: full size

Once I built a spectroscope and now i took a picture with the debayered sensor and discovered a very selective filter inside the canon 1000D. It is done with the piezo dust shaker glass, the other two I already removed destructively. This glass appears fully transparent from the front and bluish from an angled view. Looks like a good filter for visual light: [full size image] (scale in nm)

Oh, didn’t I wrote that? I measured the temperature with an infrared thermometer, was 60°C. UV duration was about 30h. The sensor was on an aluminum heat sink and it survived. No changes in hot pixel etc.

Let me conclude this experiment: After the UVC exposure there was no color degradation, but the epoxy resin became brittle and can be wiped away without much force and scratches. But the problem of the sensitive margin remains. Sensor itself and it#s image

Sorry, I was in a hurry. Top picture is the Sensor. It became brighter around the center where the light was most intense. Underneath: a plain white image with the original sensor (L) and the treated one but now without IR-cut filter ®. (same exposure time, same light) Bottom: Treated sensor remains to see colors. Small scratches appear white, micro lenses may became brittle and break away.

Hi! Sadly it had not worked as expected: A very soft Q-Tip made the scratches.

Hi, I am reading this forum several times from the early beginning on. I did some scratching on digital cameras but with short pleasure till I disconnected bond wires… I ever wondered about uv-induced bleaching to maintain the micro lenses and did not find someone saying it worked. I then faced an opened sensor to direct sun during a day in summer without success. I later tried a germicidal lamp without change and gave up, for a while! Now I had a Canon 1000D’s sensor and this high pressure mercury lamp. I broke the outer glass as only the inner glass is quartz (pure SiO2) which will pass hard uvc. The sensor was now 30h under the 40W lamp and brightens up! I have spotted some dark parts where dust has covered the sensor. So I will give it some more time the bleach even these parts. (The sensor reaches about 60°C during the treatment and is hopefully still alive)
