If you are developing a cost model for quotation/estimation purposes, we would recommend time studying a handful of existing jobs/set up's that you have, and averaging your actual CPM rate. Then determining your cost to operate from there. This wil

I'm looking for a typical SMT placement defect rate from others in the field so I can judge whether or not we are in an acceptable range. If I give you a board with 200 components (0603, 0805, SOICs, 20mil MSOPs, tantalums, DPAKs and a few 20mil fin

With a melting point of roughly 300°C, you would need to have the product see temperatures peaking around 325°C at a minimum. (I would make sure the components and PCB materials can withstand these temperatures) Most convection ovens do not go over 3

Everyone deals with a number of loose SMT parts during production. These usually come from machine attrition (dumped parts), a few parts that are lost during feeder tape changeover, dropped inside the machine, etc. I will categorize them as: A. Ide
