1. Depanelization
Is breakout tooling specially designed for the board or is a line-side Router or v-score machine used? Manual breakout = 0, 1.1 except for small support tabs in non-critical areas of PCB Can it be demonstrated that board flexing has been minimized and clearance is sufficient by 1.2 using such tooling? For v-scored boards, are boards positioned using a fixture so that the cutting tool and can only 1.3 cut occur along the v-score? Can it be demonstrated that the board is supported before and after the cut so as to prevent 1.4 board damage due to dropping? Does the press fit tooling use force feedback control that provides repeatable installation and 1.5 prevents PCB damage? 1.6 Has all tooling used at Mechanical Assembly been designed to minimize board flexing? 2.
