What do you guys rip off low grade boards before you sell them? I am about ready to take a trip to e wasted and i have about 500lbs of lowgrade. Right now all i have ripped off it transformers and AL. Oh and all of the copper.
Thanks!

yeah you pretty much got it all off. maybe the IC chips but thats really what he buys the lowgrade for in the first place.
I rip anything copper or Al and throw the rest of it in with the tin/shred, but I'm not near enough to a buyer, or feel it's worth any difference
Like the others, copper/alum, and the transformer, and wires of course. Then I toss it in my low grade/bleh pile and take it to my yard when I got enough. My yard doesn't pay much for them but it's something. As we all know, something is better then nothing.
Sirscrapalot - Goes all "Hulk SMASH!" on low grade tv boards.
I use some slip joint pliers and just start grabbing/twisting stuff off, what's left just goes in the junk/shred pile
Why would he buy low grade boards for the ic chips when about 50% of them don't have ic chips, when i'm through with them none have any ic chips.
im confused. do you tear apart to low grade boards because they wont buy them with everything on them? or is it cost productive to tear it down versus just sending it as is?
Happy honestly im as stumped as you. when i talked to easy bout lowgrade last time, i believe that was the good money make on the boards since he let me remove the transformers. most people i know strip the aluminum off as well. buying them with all that stuff removed has me stumped.
I'd like to re-open this discussion and ask, what do you do with the stuff you take off the boards? Do you take all the little do-hickeys off the aluminum heatsinks, or sell it as "dirty" aluminum? What about the transformers, do you break them open to get the copper out, or do you sell them as transformers? Most of them are pretty small. At what size does it make a difference?
Some of those little copper wound things are easy to get the wire from, even fun maybe, not very profitable, but eventually adds up. the little transformers are definitely best tossed into the transformer pile
I take off the aluminum and put it in dirty aluminum pile not worth cleaning up the little stuff
but on bigger ones if not much ill clean it up to get more for it.
when dealing with low grade I pull off all the usual suspects,
but I cut the wires off while they're still attached, so the plastic ends stay connected to the board.
not sure if that's cheating or not but that's the way I've been doing it, adds a little more weight.
Why would it be cheating, your leaving brass tabs on the board. Should increase the value to them.Quote:

Yes, the bigger ones are usually plated brass tabs, don't know about the tiny bits and pieces.Quote:

Certain capacitors have some PM'S in them but in very minute quantities. Some looked like this, definitely worth the time to pull them, if you take it easy with the needle nose you can get the legs to release from the solder.Quote:

cool, how old do you think the TV boards have to be to find the gold plated transistors?
Basicly take anything off that you can sell for better price than the board it self (low grade boards only) any other grade of board you'll degrade the board. Also don't take anything off a power board, a good example of power board would be the boards from power suplies. I take aluminum off and I clean it, it's easy and quick, I take large copper windings and IC chips. I leave transformers on becuase I get more for the boards than I do for transformers.
I only get .10 a pound for "Electronics." So I rip off everything, Motors, transformers (Including Flybacks), aluminum, IC's, those black boxes that have copper in them, and even transistors. I squeeze out every penny I can at that price.
Im trying to figure out why you would take anything off of the board at all its all weight. I guess as a downstream Im not fully understanding why one would waste the extra time when you can throw it all in one box and get paid $0.15lb. for all of it. The extra time and effort just does not seem to work with the numbers game ($$) I think the higher grade boards should take priority. Just sayin'
Ddelatorre14 is correct.. I only ask my customers to remove excess steel and plastic and they are receiving in the high twenties to low thirties/lb.....Not worth trying to recover a few extra cents for the aluminum and copper...
I remove all of the copper items, and the aluminum heatsinks and transistors.
I wish I could get high 20's to low 30's a pound. I would leave the stuff on as well for that price...Quote:

Russell you are correct.
I take of the aluminum and through it in the EXT. AL. or AL. Sheet buckets. Transformers go in the ELEC. MO. bucket.
What about heat sinks? They look like they could be copper..
I doubt the heat sinks on a low grade board are copper. But you could try a file or grinder on them just to make sure.
people take things off that are worth more than $0.15.
when looking at hourly wages, its usually not worth it, unless you have done a lot and picked up a lot of tricks, however, many peopel do it while watching tv or sitting on the porch chatting, making it not count as working hours.

Hobo.. you can get low .30s but you have to get it to me in Tampa and im not really sure that would work well for you(please note the attempt at humor)Thank you and gnite
Unortunatly we dont have any yards around here that buy low grade or any escrap for that matter. So i pull everything off the board i can sell to a yard separately then mix the boards in with shred loads.
I think the BSB is talking about a socket that is soldered onto the board. He leaves the plug connected into the socket & just cuts off the wire thats connected into the plug.Quote:

I take the 'delay line' from the boards. Origanally I thought there was gold on them, now I'm not sure. It looks like gold where the wires attached to the glass sometimes. I think the solder is silver solder.

I also get the crystals, theres several sorts. http://img.directindustry.com/images...36-2371461.jpg http://img.directindustry.com/images...64-3070267.gif http://s.eeweb.com/resized/images/re...09/28/kyocera-
They have a glass plate inside with really fine beautiful etchings on them. And gold looking solder on the cap & base edge & inside.
Common crystal http://www.zsqts.com.cn/product-phot...9S-series-.jpg & inside it. I think theres silver in there too. http://upload.wikimedia.org/wikipedi...rtzCrystal.jpg
Sorry about the size of the pics, still learning.... I did find out that a bad crystal will cause the 'green screen of death'.
who are you selling this stuff to or are you doing something w/ it yourself?Quote:

Any other pics of those crystals would be appreciated!
Also are they normally located on the low grade boards? Low grade as in TV, VCR, Stereo boards...
Yup, I find the crystals on Tv's, microwaves, handsfree telephones etc. Anything that needs a crystal to set the timing of something.Quote:

On a monitor, the computer will probably control this.
Depending on how old the TV is, the sort of crystal they use changes. Theres a sort thats in a can, like old transistors, most are flatter & larger dia.
Some Tv's have 2 or 3 crystals too, of different sizes & types.
Real old Tv's have a thin tube thats got red copper wire wound around its length, thats the sort of Tv that may have gold plated legs on some of its transistors. Its a old version of the crystal SAW.
Also, check any Tv channel changers, the sort where you had to get off your rr's to change channel. The contacts on these often have gold plating
I am saving then for PM refining, on the chance that the crystals contain silver.
I snap them off & 1/2 the time the legs stay on. They get their own jar which is 1 pint, & 2/3ds full. They might be reclaimable & the broken ones are for refining.
Unfortunaly I can't find some tin for the tin chloride 'gold test'.
Do you have pics of all items you have listed above?
Where and who do you sell them to?
The oldest TV i ran across recently was from 89, doubt there is gold in other than the crystals. I do still have all the boards I have like three trash cans full of them lol.
I wonder if it would be best just to collect them because of the market value on these items doesn't seem to be going down at all.
It seems to me you should leave the plug on the wire not the ciruit board because you get more per pound for the wire than the board. Why would you leave the ic chips on the low grade boards when you can get 5.00 per pound for them. I don't understand why you guys are always talking about poluting the ground and/or the air and then throw your circuit boards in the shred pile. I have read post saying you shouldn't leave boards outside or on the ground do to pollution yet you'll toss your boards in the shred pile.
:confused:What are you talking about? Got a quote of someone saying they through there boards on the ground?
He carries quite a few supplies, might check here; Default Page: Gold, Platinum, Silver, Palladium, Rhodium, Refining Learning Resources and SuppliesQuote:
