Cycle Time Estimates

Electronics Forum | Fri Oct 21 09:03:32 EDT 2005 | jdengler

Why don't you estimate a board, then do a time study when you actually build the board to see how accurate the estimate was. This works very well in convinceing someone how accurate you are. Jerry

PCBA Time Estimation Formula

@Evtimov My company only recently got our SMT line operational and are just starting to estimate PCBA time. I just wanted to clarify, it seems that your formula will boil down to the number of panels multiplied by the bottleneck operation. Is there

I am looking for a good way to estimate assembly times per board. We currently use an engineer who looks at the BOMS and gerbers, but are looking for an alternative. Any formulas or software recommendations would be helpful.

If you've already run both projects on your machine, then it should be as easy as taking the run-time info out of the machine for the two projects, and adding them up. I'd round up and buffer, but, I always do :) Every PnP machine I've ever worked

How is cycle time of SMT line (Chip shooter for ex) determined?

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

Average paste volume estimate

Does anyone have an easy way to estimate how much solder paste is applied to a smt pcb? I understand it varies on squeegee pressure, stencil thickness, and pitch of the components but I was looking for an average. I would assume that somewhere out th

If possible, three or more fiducials is optimal. That way scale, translation and projection can be estimated. Andy

Your estimate will become more accurate as you increase levels of the subtasks.
