I need to side mount a standard HC-49/U crystal on a board using double sided foam tape. I am looking for a source for pre-cut foam tape. In prototype runs I have used 3M #4950 foam tape cut to size one at a time. But for production I want it pre-

Steve, I'd stop worrying about the in-line feature of the printer, I've never really seen an in-line system that wasn't capable of batch operation and there will be very little, if any, cost saving associated with going batch load only. An in-line m

If you do not have one of the big in-line aqueous cleaners, then there is an easier way that is a lot less expensive. I suggest you try Asahi's AK-225T vapor degreasing solvent which has been around for 10 years now. And it is legal. If you have
