I think these would be all Telecom Grade, just want to double check. Thanks

DSC01411: Peripheral. Too many capacitors on the board. Removing them won't help the board's value and you will lose weight in the process.

DSC01409: Telecom, though just barely. Good amount of ICs, but spread out.

DSC01407: The first two in the top row and the second one in the bottom row have enough IC density to get telecom. The remaining boards are lacking the IC density required or have too many non-IC components taking up board area to get telecom.

DSC01397: This may be a rare exception for telecom grade. The IC chips are small, but I'm seeing a lot of what I believe are tantalum capacitors. You can offer it as is, but another option is to take a heat gun to the board and harvest the tantalum capacitors and sell them to a buyer, then what's left goes as peripheral grade. I don't know what the going rate is on tantalum capacitors, but if it does appear profitable after doing research on the weight and tantalum price, then go ahead and depopulate the board.

DSC01395: This would barely make telecom grade due to the power components and wire sockets present that are taking up board space. Leave the two EPROMS that are socketed in place.

DSC01394: Telecom grade. Leave the board that is soldered or socketed to the main board in place.

DSC01393: Peripheral grade. Appears to be a controller board from a laser printer. Many of your printer boards that do not handle power exclusively fall into peripheral category.

DSC01392: Telecom grade. Healthy IC population across the entire board.

DSC01391: Peripheral. Very few IC chips on the board and they are all located in one corner, with no other components helping board value located anywhere on the board.

1397 is going to be peripheral. Not enough actual tantalum there to be telco. The recovery value here is orders of magnitude below weight.
If you can sell the tantalum on your own this would be a good test board to try depopulation. tantalum Polymer block capacitors go for $8-$8.50 per pound at the moment.

1395 will ONLY make telco if you leave absolutely everything in there.

1395, you'd need to actually remove the mini power board riser to get telco.

1393 despite being a printer board has all the mobo requirements. An expansion port. Cpu + bridge. Ram port. External gold pin ports.
It's a small socket motherboard.

Not to step on toes,
This is just stuff I deal with regularly.

When the forums started several years ago, I was one of the first ones to step in and grade materials. Since changing jobs over a year ago, I haven't been as active in my posting, but I still try to chime in every now and then. It's good to know a few of the things you have seen, so I'll try to remember that as I view more posts.

Some how I just keep winding up with printers. I don't buy them I don't pay for them and in general I don't really want them but still; somehow they keep winding up in my basement. I'm like a printer magnet! :)*
They just take so long to take apart for what you get.
