Fairchild ceramic chips

Has anybody run these chips before? They look like they would have a high yield with the thick gold traces.

The main gold would be in the gold solder near the stubby pins as opposed to the traces Resa.

I've never processed any of these but there does appear to be more gold solder on those than a ceramic with a gold soldered lid.


What does the other side of the chip look like?

The bottom of the chip has nothing on it. The ceramic has holes and at each hole a gold plated pin passes through from the top.
