Wet ashing ceramics

[anachronism]

I have never run into ceramic quads before. Just goes to show the more you know the more you learn you don't know.

Ceramic quads? Nah never seen any .

Although technically those are certainly quads (exterior pins on all 4 sides) I would "class" those as "gold cap" ceramic (quad) ICs --- & not just ceramic ICs

BIG difference in yields (as we know)

View attachment 66239These are the ic chips they’re ceramic Motorola

I have a similar hand full of these exact chips. They will sit on the shelf a long time I'm sure... i doubt it will be worth processing just the few and i don't get gold caps to toss them in with.

I have about 20lbs of those I have no idea the yield I can expect from them though unfortunately

I have +/- 290 gr (580 pieces) of these ceramics squares gold cap. I will process them these week, what can I expect as yeild, just to see if did a good job in refining.

I got 9,2 gram from that 290 gr.
1 Kilo will be 31 gr then... Not a bad yield.
Will see if my next batch will yield the same..

31g per Kg is absolutely spot on the money for these.

Almost no dead weight of ceramic, just heavily plated lid and some remains of leg pads... That cannot go wrong I like when you dissolve this kind of material, you see gold in solution right away despite base metals present in the juice. Very satisfying to watch as you drop the gold the golden colour disappear and from the concentration of gold you will have after dissolution, very very dense gold powder precipitate

Thanks for confirming..
