Method of manufacturing multilayer electronic components
First Claim
1. A method of manufacturing a plurality of multilayer electronic components, comprising the steps of:
- (a) Manufacturing a laminated sheet in which layers of ceramic tape are each provided on one side with a pattern of electrodes, are stacked so that the electrode patterns on consecutive layers are offset back and forth with respect to one another, and are pressed together;
(b) Cutting the laminated sheet into segments in which consecutive electrodes are alternately exposed at a different segment edge;
(c) Sintering the segments;
(d) Providing electrical contacts which interconnect the electrodes exposed at given segment edges, characterised in that the cutting step (b) is performed by directing a focused laser beam onto the plane of the laminated sheet and by effecting relative motion of the beam with respect to the sheet so as to trace the beam along a selected cutting path, whereby the intercept of the beam and the sheet is cooled by a flow of non-flammable gas.

A method of manufacturing a plurality of multilayer electronic components, comprises the steps of:
(a) Manufacturing a laminated sheet (1) in which layers of ceramic tape are each provided on one side with a pattern of electrodes; are stacked so that the electrode patterns on consecutive layers are offset back and forth with respect to one another, and are pressed together, cutting the laminated sheet into segments in which consecutive electrodes with a gas cooled laser beam, are alternately exposed at a different segment edge with a gas cooled laser beam; sintering the segments and providing electrical contacts which interconnect the electrodes exposed at given segment edges.
