A semiconductor device is provided with a semiconductor element having a plurality of electrodes, a plurality of terminals electrically connected to the plurality of electrodes, and a sealing resin covering the semiconductor element. The sealing resin covers the plurality of terminals such that a bottom surface of the semiconductor element in a thickness direction is exposed. A first terminal, which is one of the plurality of terminals, is disposed in a position that overlaps a first electrode, which is one of the plurality of electrodes, when viewed in the thickness direction. The semiconductor device is provided with a conductive connection member that contacts both the first terminal and the first electrode.
摘要:
A jig apparatus for arraying and supporting work to be soldered wherein a plurality of lower supporting bars for supporting the lower side of a work are arranged so as to extend in a frame designed to be mounted on a conveyor holder of an automatic soldering line, upper supporting bars are arranged so as to extend above and in parallel with the lower supporting bars to press the work from the upper side thereof. The upper supporting bars have one end fitted to the frame. A gate member supports the other end of the upper supporting bars and movable up and down with respect to the frame. Work insertion openings are formed in the frame such as to oppose the gate member. The lower supporting bars are made of elongated channel members with a substantially U-shaped cross-section, each of the elongated channel members having holes formed in the floor thereof.

The present invention improves abrasion resistance and persistence of anti-fogging properties of an anti-fogging article. The anti-fogging article of the present invention includes an article, a porous film formed on the surface thereof, and a hydrophilic film formed thereon. The porous film contains inorganic fine particles and a binder. The binder covers at least a part of surfaces of the inorganic fine particles and is interposed between the inorganic fine particles. The binder contains a metal oxide as its main component and a hydrophilic organic group other than an alkoxyl group. The hydrophilic film contains a hydrophilic organic polymer.
摘要:
A coating resin composition is able to form a coating film having not only high hardness and weatherability but also high toughness, and can be cured both at room temperature and by heating curing, and further which is good at storage stability.The coating resin composition consists essentially of a silica-dispersed oligomer solution of organosilane prepared by partially hydrolyzing a hydrolyzable organosilane represented by a formula R.sup.1.sub.n SiX.sub.4-n, in colloidal silica dispersed in an organic solvent, water or a mixture thereof, and an acrylic resin which is a copolymer of acrylate or methacrylate represented by a formula, CH.sub.2 .dbd.CR.sup.2 (COOR.sup.3), and a curing catalyst. This composition is used by separating the components into two solutions and then mixing thereof as required. A resin-coated article comprises a cured resin layer of the coating resin composition on the surface of a substrate.
