An electronic device includes: a base; a conductor pattern formed on the base; and a circuit chip electrically connected to the conductor pattern. The electronic device further includes a reinforcing member which is disposed on the base to surround the circuit chip, whose outer shape is like a ring, and which includes layers stacked in the thickness direction of the base. The lowermost layer of the layers is closest to the base and softer than the layer that is at least one of the remaining layers. 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 method of bonding flying leads is capable of efficiently supersonic-bonding the flying leads to pads of a board and improving bonding reliability therebetween. The method comprises the steps of: mechanically processing the board so as to form projections, which act as margins for deformation, in boding faces of the pads, on each of which the flying lead will be bonded, positioning the flying leads to correspond to the pads; and applying supersonic vibrations to a bonding tool so as to deform and crush the projections, whereby the flying leads are respectively bonded to the pads.

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 manufacturing method for an electronic apparatus and manufacturing apparatus are provided. The manufacturing method includes applying to a surface of a sheet an adhesive to be charged into a space between a mounting board and an electronic component mounted on the mounting board, bringing the one surface of the sheet into contact with a back surface of the electronic component mounted on the mounting board and charging the adhesive into the space by bringing the adhesive into contact with a peripheral portion of the electronic component under a low pressure, and pressing a heating head against the other surface of the sheet and heating the sheet with the heating head via the sheet to set the adhesive under atmospheric pressure, in a state that the sheet is in contact with the electronic component.

A method of flip-chip mounting a semiconductor chip can carry out bonding at normal temperature and improves the positional accuracy of bonding. The method of flip-chip bonding a semiconductor chip 52 includes a step of providing a hardening trigger that is not heat to insulating adhesive 51 either before the semiconductor chip 52 is mounted on the substrate 50 or during bonding; and a step of bonding the bumps of the semiconductor chip to the pads of the substrate 50 by pressure welding or metal combining while hardening of the insulating adhesive 51 is progressing due to provision of the hardening trigger.
摘要:
A method of mounting a semiconductor chip in which an IC chip is mounted by filling a gap between the chip and a substrate with adhesive which functions as an underfill. The fillet of the underfill is made to have a preferable shape. To accomplish this, a head IC chip provided with bumps is placed on a suspension that is covered with the underfill adhesive and is provided with pads. A bonding tool presses the head IC chip and applies ultrasonic oscillation to the head IC chip, so that the bumps are properly bonded to the pads. When the head IC chip is pressed and subjected to ultrasonic oscillation, the ultraviolet rays 108 are emitted so as to harden the peripheral portion 151a of the adhesive 151 spread out between the head IC chip 11 and the suspension 12.
