We use standard "pizza cutter" type depanelizer. You just need to use knives made for aluminum boards, because standard ones gets dull quite fast if used on aluminum. CAB has special knives for aluminum, but I think other manufacturers offers simila

| A buddy of mine has problems after depaneling double sided pre-scored PCB's. Resistors near the edge, after put into the slice and dice machine contain micro cracks. He's checked for them before and after depaneling. We figure it is the sectioni

We use scored boards almost exclusively on our new products, but there are some things to be aware of. 1) If it has SMT on it, hand breaking it is a bad idea (our customers refuse to discuss it). 2) Pizza cutters are a bad idea (our customers shou

X7R >Z5U,Y5V Greater means less likely to crack or in other words NP0 is better than X7R for crack resistance. Don't think that there is a set formula. There isn't! I cracked ceramic resonators at 0.050" from the board edge with CAB M2 and M3 dep

Those pizza cutters just have a tough time with edges other than straight, don't they? [HEY, they don't cut it!!! Haaaa!!!!] Consider either routing or singulation as an alternative. Look here: http://www.smtnet.com//forums/index.cfm?fuseaction=

Looking for some direction from you folks in regards to finding water jet (or similar) depanelizers. Currently, we have the pizza cutter style depanelizers (which work fine) however some issues are coming up concering fracturing of ceramic chip cap

How do you �physically remove the solder from the fiducal prior to disposing of the balance of the rail�? We don�t HASL our fiducals. Easier to see with vid head. If you need to HASL your fiducals, consider: * Disposing of the rails with your scra

I've seen cracked caps due to de-panelling on caps 40mm in from a board edge, if the cap lies on a stress line it can be cracked quite far in, i'd go with the other replies and make sure you use a "pizza cutter" type de-panelling machine for v-scored

We use a FKN pizza cutter and found that even with 5mm clearance and the proper orientation of the part larger ceramic capacitors 1812, 1210 would still stress fracture. We have successfully fixed stress fracture problems by adding routed relief slot

Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially
