Assembly folks / layout guys / Stencil guys,
We received a fab drawing and gerber for single board but in reality it's a
panel or an array. My design guy says that leave it to fab house on
selection of panel size. It's a common practice. He thinks that different
fabs work with different materials and processes.

I do not agree with him for the following reasons. What do you think guys,
particularly in assembly house!
(1) Stencil making will be a trouble one as person is going to order based
on gerber unless someone tell him else he has to order another one.
(2) What if the job is shifted to different fab vendor. We have to start
complete process again if panel size is different.
(3) Machine programming modification,
(4) New wave fixturing.....and many more

Any valuable inputs will be appreciated.

ken patel
