This sounds like exactly what I am going through here. If you come up with a nice solution please post it. One of the things I have done is make top and bottom programs similar as possible. No I didn't say all programs the same overall just each job

Any tried and true methods for tracking WIP with a paper system? A good white paper on the subject or even a decent book reference that covers the topic would be great. It's really never been done here before and beyond establishing time standards a

Hi, On a semi related front, part of our company is a distributor (I'm not going to say who, coz that would be sneaky advertising), and on all components shipped we've added the follwing to the label: ROHS Compliancy Status(Lead free & plastics etc

thomas, why isn't it process control, you cant just think that because you've set up your machine properly ( pot temp, wave height, pre-heat etc etc )that everything is going to be ok, there are other factors that you wont find with wave riders or
