Mil-spec boards? Help!

[glorycloud]

Anybody seen cards like these before? I hate to process them, they seem like art.

I have a complete list of part numbers for them. Where can I look to see what the PM content of the cards are? Over (100) of these small cards and only (11) pounds or so.

Thanks!

yes these are older boards, good value even transistors usually have gold, some parts are better saved.

Are those transistors with gold plated bottoms and legs? If yes, it is cool, cause there can be as much as 7-12 mlgr of gold in one piece.

Each one of the little silver transistors has a gold tab coming out of the side. Some of the part numbers on these transistors are: SS1513H 8337 and SS450H 3323 nade by Motorola? Some of the cylindrical transistors have gold legs as well. Two of the boards have p/n:
90536 ASSY 7111535-02N and 90536 ASSY 7111530-01J.

Gold plated tab is a good sign....

Anybody interested in buying these boards w/o the gold legs? I snapped them off and have been soaking them in AP for about a week now. It has taken a long time for the thick gold to come off off what appears to be copper legs.

Anyway, what is left looks like high grade stuff. I am just not comfortable processing boards like this.

PM me if you are interested in them.

Thanks!

I have been in the scrap metal business part time for years, mostly dealing with heavy steel, cast iron, and base metals. During that time, I saved up a good bit of material that contains PM.

I have set a few older circuit boards aside as "collectibles". Looking at your boards, I have to wonder what they might be worth a hundred years into the future.

Maybe you could get a reverse mortgage on them. Just tell the mortgage company they are going be worth a fortune. :wink: :wink:

I actually think they could make a nice artwork display for a museum or an airport!
