And don't forget to implement the "Scotty" technique for estimating time.

Once the gerber files and BOM list are generated by CAD packages for download on to SMT production line....How is the cycle time of that PCB operation determined? Is their information with in Gerber files by which you can estimate, before actual pr

If its newer equipment.....and newer software.....usually the software for the smt machine will tell you the estimated time once the board has been programmed. If its older equipment.....get the old stop watch out.

Bobpan ..Thanks for the 1st input Let me ask in a little more detail The controller on SMT machine will understand the X-Y positions to mount the chips/transistor based on a given centroid in gerber file---the software on machines like Fuji, Assem

The latest software packages and stopwatch will do the job but if your manager is anything like mine he wants to know straight away from the BOM. If you split the bom down between placement machines i.e. caps and resistors etc on chipshooter and ICs

If the machine is on it's way..... Question is 1. What if the machine is on its way / remote site...and need to estimate (say 90-95%) probability ? A1. 1 x 8 hour shift 65% x 1 of software estimate or stop watch estimate run on same machine in a dr

What are some of the Chip-Shooter machines that have this Golden Board comparison? I am aware of a dimensional image overlay but no measurement is performed by the machine to determine accuracy on these systems that I am aware of. -JAX

Has anyone had the experience of losing components after they have been placed by the HSP 4796 because of table movement. I've worked on the 4760s, 4780s, and 4785. I don't know if this is a problem or not. We are trying to determine if this a possib

Are you sure your custoemr didn't get a little confused with what he saw or was told? When he says optical comparator is he talking about the basic component recognition system? some machines when showing the component (on the CRT) show a template th
