Abstract

The edges of printed-circuit substrates can be eliminated as sources of dust and particles by forming the edges with a router. A conventional cutter running at high speed in an oil coolant produces smooth edges on glass-epoxy panels, without leaving a resin dust or glass fiber particles that may subsequently loosen and fall off. The multiple substrates can usually be efficiently routed together using a template on a two-dimensional pantograph.
