Thanks for your help guys. We've V-scored boards in the past and it led to difficulties, as mentioned with the depth of groove etc... Our PCB's vary in shape and size drastically, and I mean drastically. So it looks as if a little more though on wh

Warpage factors can cause: 1. Boards can not transfer down conveyor belts or wedge at transitions. 2. May not enter into machinery due to interferences (like board clamps) 3. May fall off conveyor chain in furnace. Especially true of thin (PCMCI

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

OK, Pete, I just looked all through IPC-A-600G. Saw no mention of scoring anywhere. Please provide specific section number info. Thanks By the way, Chris, thank you for the information - that is really interesting stuff. Would you be willing to a

thats very close to the edge. it is preferable to have at least 3mm clearance to edge, or more ideally 5mm. If the chips are too near to the edges, you might want to modify the panel by routing through the area next to the chips. This would eliminate

It can be done and is done all the time. You need to check with your customer about this since you will not have clean square corners along the edge. If they are snapping the boards into a holder they may need the square corners to securely hold th

You are referring to the web left after the break, right? I figured it was possible, but I did some searching and couldn't find anything about it. Do you have a board or picture you could post of this?

We make pcb depaneling equipment and many of our customers do a combination of tab routed panels with pre-score in order to speed up the singulation process. If you like, I can send you a picture of an example. Regards Klaus Heimann FKN Systek Tel.

i have seen that happen when the wrong process was utilized! your boards looked like they were v-scored and someone broke them apart, proper method would be to use a scoring separation machine.. pizza cutter. this would prevent this. its not a good i
