Just a few brief notes, I managed to briefly get back to this project.
First the good news:
1) A paint stripper containing methylene chloride can be used to release the chip from the carrier. I soaked it for several days and was able with a gentle pry to remove the chip from carrier.
2) Since I had bad luck trying to dead-bug solder U1 after lifting some pads to replace a chip that died due to a shorted image chip. (This was before I broke down and bought a Weller WES51, with the right tip, maybe I would have had better luck) I bought some "QFN24 0.65mm 0.5mm to 2.54mm DIP Adapter PCB Board"s from China on e-Bay. Soldered U1 to this board by using a ETDD tip from the backside after tinning the contact pads and tinning the chip "leads" and heat sink. Also came back and used a ETU to ensure good contacts from the top. Next cut the board down to about a 7 mm square using a Dremel cutoff wheel. Stripped the solder mask off using an X-acto knife. Removed all traces from bottom of board except heat sink solder pad (but did trim slightly) using the Dremel cutoff wheel as a grinder. Soldered the board to my original board and used wires to repair. A picture will better show what I did, but no time tonight. After this, the U1 voltages were good and stable.
3) Good news is that using a socket the CCD turns out to be a very good idea. (See #4)
Now for the bad news:
4) Although this CCD is not shorted and drawing excessive current unlike the first I tried, it may not be working. Since this came from a image board bought on e-Bay, it may be that the CCD was bad before I removed it from the circuit board or I wasn't careful enough removing it. Time to debug and scope the circuit. A few quick checks makes me think the board is good. The good news is that since the CCD is socketed it is easy to remove during testing or to replace. After some additional debugging I'll see what I need to do.
Trials and tribulations:
5) I am using ImageJ version 149 from https://imagej.nih.gov/ij/index.html with the ASCOM plug ins from http://neutronoptics...com/ascom.html Had lots of trouble recently with it crashing and don't know if I forgot how I managed to use it or something changed on my system from a recent update, but in order to get it to work I need to run ImageJ.exe in Windows XP SP3 compatibility mode on my Windows 7 system. I won't mention how much time I wasted before I discovered (or rediscovered) this fact.
6) Notice that there is an ImageJ2 fork at http://imagej.net/ImageJ2 However, I couldn't figure out if it is compatible with the original ImageJ ASCOM drivers. If anyone else knows more, I would be interested in learning more about this.
7) My -15 V supply is at -14.5 V and stable. Is this in spec?
I'll report back at some point with pictures of my patch job and the results of my board debugging.
