We had a problem with 1825's close to the edge which were being sheared when the breakaways were flexed and removed manually, the resolution was to get a de-panelizer which eliminated the problem we were having.

This might sound stupid but... We had a similar issue and the solution was depaneling the panel upside down. Take this advice at your own risk...

Travis H: Are both pads of the component the same distance [0.088"] from the edge of the board?

Yes, both pads are the same distance from the edge. I also included a picture of a cracked part. Thanks,

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

Cracked parts close to the edge on pizza cutters are a common problem. There are a lot of stresses on the board as the blade cuts through the board. Raising the blade height so that the boards are not cut clean through will help. You will have to fi

One problem you may have with deeper scoring is not so much broads breaking apart unintentionally, but warping upstream while on the SMT line which can cause sagging. This may give you transport issues from one machine to another, and if you have an

| I am looking for information on the amount of stress a component sees during the depaneling process. I am currently specifying a new piece of depaneling equipment and I have not found any studies that quantitatively compare the amount of stress di

Aluminum shreds were found inside the tooling hole after depaneling. We ruled out contamination because the tooling holes were covered during depaneling. Out of three holes, only 2 holes with positioning columns inside have aluminum shreds residue.

Routing is great for odd shaped PCBs that don't lend themselves to v-scoring. changing from one shape PCB to another is easy. The down sides are you may require custom support tooling and they generate alot of dust. keeping up with the PM will be cri
