Electrical Checking of V-Grooves On Printed Circuit Panels

       Disclosed is a technique for electrically checking the
existence of V-grooves on printed circuit panels, which are formed to
facilitate severing of final circuit boards from the panels.

      Fig. 1 shows a printed circuit panel 10 which is to be severed
along dashed lines to manufacture two final circuit boards 12. V-
grooves are cut along the dashed lines such that the panel 10 can be
severed with ease by simply bending the panel along the V-grooves.

      To make it possible to electrically check whether there are
missing V-grooves, conductors 14 are formed on the panel 10 to cross
the lines along which the V-grooves 16 are to be formed, as shown in
Fig.  2.  Cutting of the V-grooves 16 will also break the conductors.
Therefore, the existence of the V-grooves can be checked with ease by
the use of probes 18 which examine resistances between the ends of
the conductors 14, as shown in Fig. 3.
