We were notified many "common" 0603 MLCCs were going to 52 week lead times.  The world is going to smaller packaging.  Ok, so how do I make 20 kilowatts with 0402 parts?  We work in brute force, 1,200 volts at 100 amps, and still use thru hole parts because they can handle the power.  I can see it now, we will use fifty 0201 resistors to get the power level we need.  Geesh!



It is going to be interesting how we build in a world of smaller parts.



I know, you can't buy a '57 Chevy new anymore.  But imagine if you could  Cool!

Of course, hence "...suitably limited implementation..." in my post.



I'm thinking of assembly problems: printing, SPI, placement, reflow, AOI etc -  even if one could come up with a suitable mixed footprint stencil aperture, would the resulting solder joint meet IPC-A-610 visual inspection acceptability conditions for example.



Then there is the in-service-reliability aspect of the solder joints
