An electronic device includes: a base; a conductor pattern formed on the base; a circuit chip electrically connected to the conductor pattern; and a reinforcing member which is disposed on the base to surround the circuit chip, whose outer shape is like a ring, and which includes concentric rings as an internal structure. The electronic device further includes a sealing member which fills an inside of the reinforcing member while covering the top of the circuit chip, thereby sealing the circuit chip on the base.

The structure of mounting an electronic component on a circuit board is capable of securely flip-chip-bonding the electronic component having bumps, whose separations are very short, to the circuit board without displacement. The structure of mounting an electronic component on a circuit board is characterized in that bumps of the electronic component are respectively flip-chip-bonded to electrodes of the circuit board by applying ultrasonic vibrations to the electronic component, and that a center of each of the bumps is previously relatively displaced, with respect to a center of each of the electrodes in a width direction, in a direction parallel to a direction of the ultrasonic vibrations.

A slider tester includes a driving unit that rotates a test medium, a set plate that detachably supports a slider as a single body, and an investigating apparatus that is electrically connected to the slider supported by the set plate and investigates the characteristics of the slider. A movable support part 30 that tiltably supports the slider is provided on the set plate. There is also provided a pressing mechanism that elastically presses the slider via the movable support part toward a surface of the medium to dispose the slider floating over the surface of the medium. The pressing mechanism includes an elastic body 56 composed of a plate spring that contacts the movable support part and elastically presses the movable support part.

A method of flip-chip mounting can reliably and stably mount a semiconductor chip to a mounting substrate while avoiding problems such as damage to the semiconductor chip due to a difference in thermal expansion coefficients between the semiconductor chip and the mounting substrate. The method of flip-chip mounting a semiconductor chip supports a mounting substrate on a stage in a state where a resin material has been supplied onto a chip mounting surface of the mounting substrate and presses the semiconductor chip toward the mounting substrate using a pressure/heat applying head to bond the semiconductor chip to the mounting substrate and thermally harden the resin material. A concave part is provided in a support surface of the stage that supports the semiconductor chip, and the semiconductor chip is bonded to the mounting substrate by pressing the semiconductor chip toward the mounting substrate using the pressure/heat applying head in a state where the mounting substrate is bent toward the concave part.
