Unless its dirt cheap stick with a 3AV or better. The 3S is SLOW. 3AV's go around $20K to $30K (I can get you one for $25K with 75 8mm feeders). The machines are pretty good but dont expect perfect results with fine pitch parts. We ran down to 16mil

Stability of process is what your measuring so lets not assume a stable process(if your process was perfect you would have no defects). With no test a medium complexity board will be around 68.7% (according to Consulogic). I dont have many other sour
