For the most part those boards are low grade. the first on could be called riser card or expansion boards back plain. If they where mine and as I have to pay to ship my boards I would take all the others and strip off the parts that are sellable and sell them and sell the rest at my scrapyard for .10-.40 a pound. The last one has some good connectors and tantalum caps that I would remove that send it on.
hope this helps

I would definitely not sell them for 10-40 cents because most of them have gold fingers. Email those pictures specifically to one or two of the buyers, because you might get finger card prices that are more like $4+ per pound and worth shipping. At the very least, cut off the fingers and sell those for $70 per # if you're going to just scrap out the boards.
I said that in my postQuote:

A buyer mos likely won't give $4.00# on heat sinks and transformers the had little to no IC's in them.
Just giving my opinion, no need to get hostile. I recently sold 20# of boards very similar to these that came out of an old phone system for $4 per # to Ewasted. They had heatsinks, transformers, etc. in a similar style to these boards. Just don't want anyone to lose out on potential money and the only real person who can give pricing would be the buyer.
nice headed discussion, love it, but now its time for a curve ball, looks like TELECOM boards to me, i also see a couple backplane boards in there, out of a vintage server/telecom server
First two pics are backplanes, the rest could be from an older copy machine since on the third pic the writing says "mfg for xerox corp". I have also seen boards like those come out of test equipt like occilliscopes. NOt sure if i see telecom grade though...just my
.02 worth.
I am seeing a lot of light green areas on these boards, Light green areas are a layer of gold plating that is under the top coating layer. So that puts all of it at low grade telecom / green motherboard grade depending on who your buyer is and who is grading that day. You still need to pull the transformers/aluminum/ caps to sell it like that though.
Im sticking with my guns on the telecom grade, because all of these boards say "component side" on them. That tells me this all came out of the same server. I dont think they used backplanes in copiers, but i am usually wrong, so there you go.
Those top two are older 68-pin SCSI RAID array boards, probably be(or at least "should" be) rated along with higher grade backplanes
Top right on the top one has two switches with a clear casing around them. I've seen those switches discussed in some thread here that discussed them having a good amount of gold on some parts inside them, but I don't remember exactly which thread, or what it was all about
The rest look like 80s circuit boards, which probably shouldn't be lightly dismissed either, although you won't likely find buyers knocking on your door for them ; )
The first two are backplanes $4-$5lb. The rest I have to agree JG that they should go as low grade telecom. Probably from some old CNC machines. But you do have to remove the tranformers and caps.

i agree with ct's estimate on the backplanes, the lack of gold plating and the relays are holding them back from the typical $9-$10 pound range
Jg i never said the backplanes were from copy machines...re-read my post. I said the first two were backplanes and the third picture on the bottom right corner said mfg for xerox so i put an educated guess out there that they may be from older copy machines since that is what xerox is known for. But then again I am usually wrong as well:)
I can't be hundred percent sure because the pictures are a bit blurry but those things look like relays to me. I noticed them right away because I worked in Building Automation for 4 years and relays of that type are used extensively in Roof Top Air Handlers, Chiller Control boxes, and Variable Frequency Drives.Quote:

This type of relay is usually mounted to a block and have bladed contacts but I've seen them with pinned contacts mounted to older boards as in your first image.

These two pics show the gray block they are mounted to. The screws are where the high and low voltage control wiring connects. The upper tier screws are the low voltage control connections, the lower tier screws are for the high voltage wiring. You send a low voltage signal such as 24VAC to make and break the contacts to start and stop high voltage motors such as fans and pumps.

I don't recall this type of relay having gold plated contacts but I could be wrong.
I have one sitting on the work bench at home I haven't smashed it open but it looks pretty simple and only copper inside to me.
Most of the time when I scrap a relay like that, the centre pole is silver & the outer two are a silver/copper backing. Theres two 'sets' of contacts in each one. (6 contacts in all)
