Patent ID: 6927157

Claim:
Method for producing a composite comprising a tested integrated circuit and an electrical device, having the following steps: (a) applying a flexible elevation to a circuit substrate of the integrated circuit; (b) providing a rewiring device on the circuit substrate with the formation of a ring around the flexible elevation and on the flexible elevation with the formation of a contact-making device on the flexible elevation, the ring and the contact-making device being electrically conductively connected to one another; (c) carrying out of a test of the integrated circuit with temporary utilization of the contact-making device on the flexible elevation; (c) applying solder to a contact device of the electrical device; (d) placing the tested integrated circuit or the circuit substrate onto the electrical device with the contact-making device being aligned with the contact device—provided with solder—of the electrical device; and (e) reliquifying the solder in such a way that it forms a permanent, fixed, electrically conductive connection between the integrated circuit and the electrical device, wherein the solder completely surrounds the flexible elevation upon reliquifaction.
