HI all with regards to below:
scoring (or v-grooving) is a cheaper way to manufacture boards as the scoring tool has to remove less material, so it can move a lot faster. The boards will be a lot cheaper with this method. The tradeoff is that you need more clearance from copper and components to the edge of the board, which may or may not be a problem depending on the design. Routing can be used with a panelized manufacturing process, you just need to leave some areas for break off tabs - this is a small area that is not routed, but several small drill holes are made to enable you to snap them out of the panel after the boards are populated. cheers > > > Secondly, some FABSs specify different distances between > Pad/Trace to Board > > Edge for 1) Routing Method 2) For V-Cutting (scoring).
