There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram

I'd say it all depends on the CM, and how they cost out their production floor. I've seen everything from a flat cost per component placement (something like .05/machine placed smt part, .15/machine placed tht part, .25/hand placed tht part) to stra

One problem you may have with deeper scoring is not so much broads breaking apart unintentionally, but warping upstream while on the SMT line which can cause sagging. This may give you transport issues from one machine to another, and if you have an
