We design a number of circuit boards which are oddly shaped, and must use breakaway panels and tabs in order to facilitate assembly. We use a router bit to create the void between the panel and the board itself, but leave a small breakoff tab for the connection. Our previous fabrication vendor would smooth the rough burr left by these breakaway tabs, but boards from a new vendor are arriving with the rough burrs intact. Question: Is there an IPC specification that dictates the allowable height of these burrs, or do we need to specify on the drawing that the height be witnin "X" mm of the board edge??
