Abstract
A hybrid module comprises a plurality of insulating layers which are laminated on one another, circuit patterns formed on each surface of the insulating layers and/or formed between the insulating layers, wherein the circuit patterns are connected with one another by through hole conductors. Further, the insulating layers are formed of layers having a transmittance of a laser beam, wherein the circuit patterns, which are formed between the insulating layers and overlaid on top of another, are irradiated with a laser beam to be thermally fused.
Claims6
A method of manufacturing a hybrid module comprising the steps of:
- providing a plurality of insulating layers, said insulating layers having circuit patterns formed on opposite surfaces thereof and/or between adjacent insulating layers and through holes with conductors provided therein electrically connecting the circuit patterns formed on the opposite surfaces thereof;
- laminating the insulating layers on one another such that at least a part of the circuit patterns on the facing surfaces of adjacent insulating layers overlay each other;
- and
- thermally fusing the overlaying circuit patterns to each other by spot welding to form the hybrid module.
