Is there an R and C part size, with its PCB footprint
between 0603 and 0805? Maybe a metric dimensioned part?

The footprints are guidelines and will dominate fit. Adjustible per
your process control.

A 'skinny' body is always available by mounting parts on their side,
but not for automated processes, unless specially taped.

Usually capacitors with significant body thickness...

I like the 0306 caps, the ones metalized on the long sides. Great for
really fast stuff.

Is that green thermal epoxy on the IC's?

Yes, it's there to obscure the part numbers. It's rock-hard.

I do that a lot in protos. Sure makes the tweezers easier to handle.

Sometimes. This is a cool and unique product, which uses parts
off-label, and it wouldn't be hard to copy. It's not my function to

If you want to obscure the part numbers it is better to grind them off -
acetone can often be used to remove hardened epoxy -sitz-bath-...

This Thermalloy green thermal epoxy is brutal, really hard to remove.
