A self-adhesive flexible circuit for printed circuit assembly repair is provided. The flexible circuit comprises a carrier film, a circuit trace and an adhesive. The flexible circuit is placeable on a printed circuit board having a circuit assembly and allows simple repair of boards not designed or manufactured correctly and which contain undesirable short or open circuits or misrouted traces. The flexible circuit allows for placement in a desired location, adherence to the circuit board using its own adhesive. The flexible circuit can then be electrically attached, i.e. solder or conductively adhered, to the board.

Self-adhesive flexible repair circuit

A leadless chip carrier is attached to a printed circuit board by soldering its input-output connections to the printed circuit board and also by providing an adhesive between a central portion of the leadless chip carrier and the printed circuit board. This adhesive provides increased mechanical strength to the connection, improving its tolerance to temperature cycling. The adhesive used may be the same solder used to make the input-output connections.
