The Gustavus Thread

[PartTimeScrapper]

why would you put lowgrade in this shipment? You have to pay $1 per pound processing fee. So anything worth less than a dollar you would be paying them to take. Same goes with metal brackets on PCI cards for example. Why pay them $1 per pound of brackets?

My yard counts anything that is not motherboard, pci or cd/dvd as low grade. However, other buyers have bought other boards - green on both sides- for much more. One person's low grade may not be another's . When you process you go by what it yields in metals, right? I'm not talking about brown or even half brown boards. I should have noted that.

Scrapette this is the biggest advantage of sending your material out to a large company such as Sipi who deal in the final end of the product. If you live close by a Sipi location make a day of it, bring your camera, note book then pick a few brains. Make observations of how they are receiving their inventory and ask plenty of questions these guys are here to help you become a customer.

The lower echelons are eager to move on so try and speak with a foreman who has been with the company for a few years and truly knows the business, this is how contacts are bonded.

I wish you the best of luck with this endeavour, oh and happy Valentines Day.

On a side note, most mother boards have layers of copper circuits impregnated inside the the boards, invisible to the beholder of such treasure. I’ve seen as many as 6 layers but when you look at the board you only see the top and bottom layers which are called solder layers.

Yes your correct, the value is in the metals recovered, the green boards were made during a time when the manufactures did not know the technology to scrimp on copper traces, gold plating on fingers and the amount of chips required. Chips on newer boards may actually have aluminum bonding wires inside instead of the traditional gold. So the guys buying tend to error in their favour.

If your paying a dollar a pound to have Sipi refine your boards it wont matter which colour they are, just strip off the excess materiel before shipping.

As a matter of persoanl interest, keep track of how many lbs green, brown and purple were added into the shipment.

If your serious about shipping a load, I will take some mother board round capacitors like the one below, then acid treat them checking to see if there is any silver, otherwise the foil is aluminium.

I would like to assist you in making this first load profitable, if there's no silver in these capacitors you may as well discard the un-wanted weight from the boards.

I've designed 0.062" boards with up to 14 layers of 1/4 ounce copper. In the old days there was a "window" that showed each layer of copper with a number on it through the different layers.
Gus, have you sent out for an assay of your slurry? How do you inform them of what the slurry may contain?

Happy Belated Valentine's Day to you, Gustavus.

As far as shipping a load to Sipi, I don't have nearly that kind of volume yet. But I hope to move somewhere later this year where I can get it.

So my current interest falls mostly in the research category of what to do when I get a decent volume.

I will keep an eye out for those capacitors however.

Thanks for all the helpful information.

With so many varying boards that would be in a load, is it worth it to check a sample of these? Or in other words, are there actually that many that contain silver?

I doubt there is any silver bonding the foil to leads in this type of capacitor this is why I suggested to Scapette to remove them from boards as they are to be considered as excess weight that she would be paying a $1.00 lb to process. I'm trying to make her shipment more profitable, she is not afraid of work.

Oh, I apologize. I misunderstood you then. I take these off of my boards as well..as far as i knew they were basically dead weight. They get tossed in with my low grade boards.
