Any thoughts on these green boards?

[joem]

I picked up about 30 pounds of these today.
The small circles are 2 x 2 and the large 3 x 3.
There are no surface mounted devices on most of these.
These are from outdoor gas meters from control microsystems.
I was told there are two garages full of these and a deal can be made.
What do you think ?
Glondar are these good candidates for recovery for you?

Those would be good for a cyandie strip

Any idea of the total weight available Joe?

I'm not sure of totals. I need to meet with the guy at his storage location to get an idea. If amounts warrant it I may need a truck to get it all.

Hey Joe. Nice find. PM sent.

How many pieces made up the 30 lbs? Also, how many pieces are from the from the first set and how many from the second set?

Ok just weighed it and I was off by 2/3 in my guessimate. I actually have 55 pounds of the 3x3 and 50 pounds of the 2x2 as well as a sample pound of jumper pins.

So, what you're saying is that you have 105 lbs total? If so, you were off by 75 lbs.

Also, they don't look nothing like the pictures in your original post. What are they?

Oh yeah I was off, they were small as I loaded then so I did not notice the weightAlso, they don't look nothing like the pictures in your original post. What are they?
Are you talking about the pins? They were also given to me with the boards but I did not post them until I took a picture just a few minutes ago.Kevin

Right, I understand now... but what is the weight of the boards.... and how many of each? The 1st set weight/count and the 2nd set weight/count?

The reason I'm asking is that I may purchase, but I'd still like for everyone to know what to expect. The lot looks healthy, if I may say so. I'm just trying to do some figuring.

they dont seem to be worth refining. i would be happy to help out a fellow member and give you your money back on them and what the heck, ill even throw in shipping to get them here. :lol:

 

[joem]

ok I went back and re-weighed the boards.
I undid all packaging, found some other scrap at the botton of a few boxes, re-set my scale (my mistake the first time - sorry)
here are the corrected numbers and count
NOTE : there is no metal what so ever under the solder masks, all gold visible in the pictures is what is there.
the 2x2 discs = 28 pounds ( yeah my bad on the first weigh in) - 135 sheets of 12 discs per sheet ( 7x9 sheet size)
the 3x3 discs = 58 pounds - 219 sheets of 6 discs per sheet ( 6 1/2 x 9 1/2 sheet size)
each sheet is about 1/16 - 1/8 thick
All boards printed front and back as per pictures.
I can't tell you thickness of gold plating
LOL I feel like I'm writing an ebay ad, I'm not, I'm just getting info on boards I've never seen before

I may be calling upon you Geo

Joe, guess what, I'd save this post because you're giving more information that WILL help people determine if they will buy the lot or not if you decide to eBay this stuff. Maybe you'll break it down into smaller lots. But the information is really informative and I appreciate you taking the time to let us all know what you have concerning this lot.

I may PM you Joe.

I've always done business in one way;
Find a buyer first. It's what I tell every newbie who Pms me.
No sense filling up a garage with things that sit for years. Get it in, move it out, and find the next one.
In this case I'm still investigating the logistics of all this.
These boards are a sample brought to me. I still need to see if it's worth my while ( gas being a big factor), and whether this person is looking for some cash or they just needs the space cleared.
If it does not work out then no worries and I can still keep the boards.

I would process like fingers in AP. It will probably come off as a mixture of foils and powder.

Foil and powder in an AP tank?

The only way that will happen is if your solution has too much oxidizer in it. Once your AP solution is started, a good way to prevent this from happening is to simply use air stones instead of making additions of hydrogen peroxide. What happens in the presence of too much oxidizer, is that Au will be dissolved, when the solution becomes pregnant with Cu, Au will cement out as powder.

On the boards themselves, since you stated there is no Au under the solder mask, I would put them in an AP tank but dissolve the base metals before doing so with an HCl soak. If there was Au under the solder mask, then I would process in HCl, then a solution of lye to remove the soldering mask, then AP.

On your pins it looks like there is plastic. I would attempt to remove as much plastic as possible, there are numerous posts about how to do so on the forum. Then, either process with an HCl bath, collect the foils and process with HCl/Cl, or strip in a sulfuric cell to de-plate the pins. I use a sulfuric cell for pins to good effect.

Scott, you've made an excellent point that I'm going to do a video on.... and that's the plastic on the pins. I bought 20 oz of gold plated pins from someone, but after I stripped off the plastic, there was approximately 9 oz of pins. Remember.... I paid for 20 oz of pins.

Texan was right the gold will most likely be powder that is extremely thin plating only meant to protect it till it's components are applied. some may be foil most will not. Think of cellphone boards pretty but not thick or backs of ram.

Calculate gold a 4-10 micro inches to be safe 800-330 square inches to equal a gram. I think more emphases should be put on surface calculation. Early in the forum this was the case lots of great reads about it.

best tool ever http://goldnscrap.com/index.php?option=com_content&view=article&id=72:gold-plating-calculator&catid=49:calculators&Itemid=66

Gold plating on your jumper pins say is 30 micro inches thick than every 3/8s of an inch is worth about $0.012. S each bundle if partly plated is worth $0.12+-gold price. Completely plated $0.34 each.

This was put on with math it should be bought that way.

While this is true, truth is also that if plating is thin like flash plating on newer boards it will come off as powder. I have seen this many times and I rarely put more than 0,1l of 3% H2O2 in about 3-4l of HCl when I make my AP.

 

[joem]

Well I can help in this debate. The gold on these boards are a deep rich yellow not a shiney plate as seen on rca jacks, and deeper in colour than usb ends. The colour is similar to the nortel test pieces I have which are very thick plated.
