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

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

Three main groups of depaneling equipment are: 1 Scoring: Limited to straight edges and mainly 90� angles 2 Routing: And a cloud of dust 3 Singulating: Hard tooled by board To get started understanding the suppliers look here: http://www.cassembly.c

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

Chris: Whatever way you decide to define your pads, use the same type on the component and the board. Non-solder mask defined pad advantages: � No point-of-stress concentration at edge mask and solder ball � No CTE mismatch at edge mask and solder

We did this for BGA pads, but have not thought about other types. So, this may or may not apply for those. Pad defined by:||Advantages||Disadvantages Non-solder mask||No point-of-stress concentration at edge mask and solder ball||Smaller pads have
