What we did was design or panels with routed out edges held on by tabs. This was very effective. All we use is a pair of pneumatic scissors to cut off the tabs. We are using from single-to 13 layer PCB's and we have had no problems with delamination

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=

Don't V score, unless you absolutely have concurrence with your QUALIFIED fab and assembly operations. Routing is best for all chip devices close to board edge. It's better and cleaner for everything when seeking quality and reliability. Visit htt

I have never heard of heating the board for separation. You may want to try some of the following. -Using a roller cutting type depaneler helps reduce the stress. -Using a combination of routing in areas with components near the edge and v-score th

Hi C-Dig, Are you testing circuit boards on a static mat? It could be conductive, which might short things out. I've seen this happen to our bench techs. You might want to look at getting a set of helping hands. The gizmo that actually holds the

I have a small board in a 5x5 array. Thickness is .014". The fist build, the array was all routed with mouse-bites. Customer doesn't like the edge left by the mouse-bites. Board house says they can't v-score a board that thin. I'm not sure what o

I have a PCMCIA type pcb with an 0603 resistor situated exactly half way along the longest edge the device is 2mm form the edge of the pcb. I have experienced incidences of the device fracturing after breakout (hand operation) (pcbs are routed) Coul

We have an array of boards that are difficult to depanel due to components being close to the edge. I want to route a space between strips (boards are 14" long x 1" wide) and have breakaway tabs like mouse bites, but the customer won't accept the ja

I asked the same question a couple of weeks ago. I received a lot of e-mail from salesmen et al trying to sell me equipment costing several thousand dollars. I was glad to get all the information I could, but there was no way I was going to get a PO
