These are some various boards I have from medical imaging equipment.

1st 3 pics of another type, which I have a box of. Double sided gold fingered connector, highly populated with chips.


Next is 3 pictures of a transformer. Obviously, I'm not going to ship this, but I just wanted to get some opinions on what its worth, etc.. I was offered $0.18/LB, but I'm debating if its worth stripping the copper.

Next group is 4 pics of various single boards, some with gold fingers.

Next 3 is of a board I have a pile of. I believe these were part of an AC-DC converter circuit. They had a bunch of aluminum heat sinks which I removed.

Next is some gold tipped ribbon cables.


Please ID/grade, as well as offering any advice on whether anything needs to, or should come off to maximize profit. Keep in mind, I do not have advanced technical electronics knowledge, and would not be stripping for usable components, or to attempt to refine anything,etc...

You can certainly remove the wire from the transformers for insulated wire value. There are various methods to do this. If you don't mind spending the time, you'll get copper, steel and then plastic from the bobbins to throw away.

Telco.

Depends, on how big the transformer is. It looks like #2 in the ceramic coil, and #3 in the cardboard filament coils

grr. Bottom end of peripheral since you've got the two fingers, and come good coper contacts as well.

20180430_155149
Cut the wires off.
I'm going to say midgrade as a BASE; this may get an upgrade on inspection on site so email Chris with your order number and a photo. Looks like that MAY be silver plated copper/brass. if the solder is ALSO silver containing, an upgrade MAY happen.

cut the fingers. The board is mid grade regardless. So trimming the gold fingers is wise here.

20180430_155105
Mid grade here. (like 155149 there's some room here after onsite review)

20180430_154819/20180430_154808/20180430_154802
mid grade

20180430_151906
if it has ICs on the flip side peripheral.
If no ICs gold pin connector; though if that's the case I'd be snipping the pins loose and sending them in for a gold pin quote.

flat wire connectors that are gold on BOTH sides can be trimmed and tossed into gold fingers.

silver wire ends can go with silver/tin ram as long as you have over a pound of the category.
