Hi, I got a new project, and need to provide customer the ICT (In-Circuit-Testing), FPT (Flying-Probe-Testing) process quotation. The new PCBA contains analog components, digital components, and some BGAs that can support Boundary Scan. Does anyone

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

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

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

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.

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
