| 摘要 |
The present invention is directed to a method of making flexible interconnect packaging, in particular, packaging for fingerprint sensor chips. The chip is mounted on a flexible substrate having conductive traces leading to a connector at an end of the substrate. Wires are used to connect contact pads with the conductive traces, and a rigid frame is mounted below the substrate and chip. The conductive traces are preferably internal within the substrate and are exposed by forming a cavity in the substrate adjacent to the chip. Also disclosed are electronic devices which incorporate the foregoing fingerprint sensing apparatus.
