Unfortunately, the details in IPC-2222 do not give any dimensions, only tolerances. In the January 1999 IPC Designers Council Technical Journal there is an article concerning V-Grooving. For .062 FR-4 material they specify that the material remaining between the grooves should be .016. ---------- From: Joseph E. J.

Is there a web thickness spec'd in the IPC specs somewhere? Is there a thickness that some have just found to work from experience? We can spec v-score depth, but I would rather spec an IPC standard. We have boards coming in with varying v-score depths, and some cannot be removed easily.
