Back in the old days, 0201's were a pain in la derrier - yields were lousy, tombstoning was rampant, and at the end of the day, for some reason, if you looked in the bottom of the SMT machine with a magnifying glass, there'd be a bunch of stray orphans down there. And that's if you could even find an SMT assembler who could do 0201.
But seems like these days, every smt assembler offers 0201, and in the last bunches of boards I've had done, the 0201 defect rate was exactly 0.0%.
So has mankind solved 0201? Is there any professional SMT shop that does NOT offer 0201?
