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

Brian, We recently investigated a depaneling press that might suit your application. The labor savings over pizza cutting will probably make it justifiable for you. The company seems to be lesser known in the US, but is partnered with a Japanese c

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

OK Pizza it is then, here goes. Dewetting of Ni/Au pads, paste favouring the Tinned component lead hence excess paste wicking on top of the components. Reason is EITHER Nickel migration into the gold due to high levels of Ionics from poor rinse OR mo

I also forgot to mention that the pizza-slicers you are using can get out of spec and may need periodic calibration. By cutting too close, these can over-stress your pcbs as well. Do you only see this problem at one cutter or does it matter? Also,
