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 .

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.
