 (2) Make a circular cut at a distance L (detail A1).
 (3) Remove the insulation.
 (4) Unwind the braid (detail A2).
 (5) Cut the braid to get the length B (detail A3).
 B. Method "B" (Ref. Fig. : Method "B")
 (1) Strip the bonding wire to the length A (detail B1)
 (2) Make a circular cut at a distance L (detail B1).
