Patent ID: 8541685

Claim:
A flexible harness adapted to be detachably connected to electrode pads of an electric/electronic component, the flexible harness comprising: a flexible insulator film; a conductor pattern formed on the flexible insulator film; a terminal plane which is an end region of the conductor pattern; and ball-like contact bumps formed on the terminal plane, each contact bump including a core made of an elastically deformable resin and an electrical conductor layer surrounding the core such that a detachable connection will be formed between the ball-like contact bumps and electrode pads of an electric/electronic component and the detachable connection will be free of a solder connection between the ball-like contact bumps and the electrode pads, wherein the ball-like contact bumps are fixed to the terminal plane by soldering, and a solder connection between at least one ball-like contact bump of the ball-like contact bumps and the terminal plane is thicker than at least one other solder connection between at least one other ball-like contact bump of the ball-like contact bumps and the terminal plane.
