摘要:
An electronic device including a semiconductor device with a plurality of bump electrodes, a mounting board connected to the semiconductor device, thermally expandable particles, and adhesive. The thermally expandable particles are provided on the sides of the semiconductor device and the surface of the mounting board around a projected area of the semiconductor device. The adhesive is provided on the sides of the semiconductor device and the surface of the mounting board such that it covers the area of thermally expandable particles. This improves the impact resistance of the semiconductor device soldered onto the mounting board, and also facilitates removal of the semiconductor device from the mounting board when the semiconductor device needs repair.

An optical pickup includes an object lens; a lens holder for holding the object lens; a visco-elastic suspender for suspending the lens holder so as to be movable in a focusing direction and a tracking direction; a driving section for driving the lens holder in the focusing direction and the tracking direction, the driving section including a magnet, a yoke and a driving coil provided on the lens holder. The magnet and the yoke form a magnetic circuit. A heat-insulating area is located between the object lens and the driving coil, and the heat-insulating area includes a heat-insulating material which has a thermal conductivity lower than that of the lens holder.

The present invention provides a display device that prevents damage on a display panel even when the display device drops or falls down during handling. The display device includes: a PDP (10) including a front panel (20) and a back panel (30) that have peripheral portions joined to each other by a sealing material (36); a chassis member (44) supporting the PDP (10); and a housing enclosing the PDP (10) and the chassis member (44). The housing includes a front housing portion (41) provided with an opening (54), a side housing portion (51), and a back housing portion (42). The back housing portion (42) is provided with a drawn portion (62), and a top part of the drawn portion (62) is coupled to the chassis member (44) by a fixing member.
