Scott, Likes Scoring - PCB Cost - Less PCB cycle time - Easy to separate with cheap tools - Good for board dimensions with > 10 mils tolerance Tabs - Unique for PCB with irregular shapes. - If you have good singulation system, you cand have < 10mils of board tolernaces. Dislikes TABS - Hard to separate by an operator. - Equipment for singulation is expensive. - If you use have a big panel, you'll have very flexible board and can cause problems in the Pick'n Place Machine or in wave Solder, if you don't use fixtures. Scoring - PCB's with regular Shapes (squares, rectangles) - Not good for board tolerances < 10 mils - You can have some problems due to excess of burr in the scored board edges - V-Grooves only in lines across of Process Panel. (some PCB shops can do score jumps, ie:Pro-Tech).
