At 250K / month, you may need a few Mydatas. They are great machines but not all that fast. Bottom line, without a BOM, size board or panel size, no one in their right mind can tell you what machine to go with. They can tell you what they like, bu

Use a Cpk study on your screen printer. Deviation from print to print. Most reutable surface mount machine companies will supply you with their Cpp study they performed on your machine before they shipped it. On ovens use your profiler. You can
