i'm sure that is a CPU out of a projection TV.

This chip is not even worth processing, yield is way too low.

I'm gonna say it's a pen cap from a Bic ball point. Probably blue ink.
But that's my old school guess.
B.S.
I have a few like this from projection TVs. Not all but a few TVs have these.

Dynamic is currently paying $30 per lb for DLPs - they are the only company I am aware of that has a price listed for DLPs in their processor price listing

Here is one you may never see elsewhere. This is one of the three DLP chips from a cinema projector light engine, and it's a 2K chip (2048x1024 resolution). The latest generation are 4K or 4096x2048 resolution. The size of the 4K chip's mirrored surface really isn't very much larger, the individual pixels are just smaller.

Sorry, butt we are recovering gold, even a single pin is worth it.

But, there are none... so it is not :shock:
I've never seen one of those, but, what is that yellow stuff?Alentia said:
That's surely what it looks like, especially those little dots - they're probably thick if they're contact points. The lid looks gold also but there are other things it could be. The dots seem to cover about 1/2 of that particular area of the part. The lid, if gold plated, is thinner, maybe a lot thinner.mscrap said:
Show us what's inside? How much does 1 part weigh? What's its dimensions? Is the lid magnetic?
Good photos, by the way.

it also has bonding wires much like a processor chip. from my understanding, the bonding wires are gold.

Bonding wires & Au plating (as pointed out by others) & maybe the braze between window lid & ceramic
These are a new item on Dynamic's CPU price list ($30/lb) --- I would have to assume they had an assay done on them to come up with a payable price added to their CPU pricing --- so recovery is going to be a little over the $30 they are paying

This thing weight about 40gr as I remember correctly. There are little or none bonding wires inside. Plating is very thin both on top and pins. It yields around or less of P4 processor. Top base as I remember correctly looks and feels like tungsten copper alloy.
