My original question Is anyone familiar with this type? The insulator material seems to have a reaction to acid. I collected several hundred this last weekend.

That specific chip? Or are you making a joke?
 
Thatsfunny has been banned, he's the second coming of Toddntucson7. Don't believe a word of what he is writing.

Don't worry, it's the first picture in this article.

As I said, Todd is not to be trusted. No one I would like to deal with.

We have our irons in the same fire it seams... I two have access to Many older P.C. component. I'm in a good roll though, I don't purchase them. There given to me. My production/refinement cost is again next to 0. Only investment is oh so precious time... (And my lady's nerves) though most of my "goods" do seem a bit more promising. Let us compare, yes?
 
For Pt in hard drive disks, check my posts on the 1st page of this thread.

To make a long story short, my conclusion is that, at today's Pt price, the disks that do contain Pt only contain about $.007 - $.035 of Pt per disk.

Per the underlined above - AND the problem with the fact that only SOME in fact have Pt & IF they do it is such a small amount --- there is the fact that there is no way to tell which ones do & which ones don't --- which means you would have to process ALL of them (including those that don't) to get the Pt from those that do

So you can cut that 7 tenths of a cent to 3.5 cents in half - "at least"

I guess if it's just a hobby there is nothing wrong with spending a dollar to get a return of 10 cents worth of Pt (probably more like spending 10 plus dollars to get 10 cents worth of PT)

There's actually way more value in the rare earth magnet in the HDD than in the coating on the platter.

The boards are also very high yields per Kg. I'd take Chris' and Kurt's advice and forget it.
