Affixed to a projection (111) of a glass substrate (110) included in a liquid crystal module (100) are a first ACF (150a), which has low surface tack strength but high connection reliability, and a second ACF (150b), which has high component attaching capability attributed to high surface tack strength. With these, an LSI chip (130), electronic components (150), etc., are mounted on the glass substrate (110), so that high-speed electronic component mounting can be achieved while ensuring connection reliability.

A display device that can easily attach a connection member to a display panel is provided. This liquid crystal display device (1) includes: a liquid crystal display panel (2) that includes a TFT substrate (10) and a CF substrate (20); a FPC (30) that is electrically connected to the TFT substrate; and a FPC (40) that is electrically connected to the CF substrate. An alignment mark (13) is provided in the TFT substrate. An alignment mark (41) corresponding to the alignment mark (13) is provided in the FPC (40).
摘要:
Provided is a circuit board in which visibility of an alignment mark is improved.In a case of manufacturing a substrate module in which a touch panel (20) and an FPC (50) are electrically connected, an alignment mark in the FPC (50) is formed by an opaque metal film, so that visibility is high. Consequently, when an alignment mark (25) in the touch panel (20) is also formed by an opaque metal film, the visibility of the alignment mark (25) also becomes high. By performing alignment using the alignment marks having high visibility, alignment between the touch panel (20) and the FPC (50) can be performed easily with high precision. As a result, the yield of the substrate module increases and modification of an alignment apparatus used for alignment becomes unnecessary, so that the manufacturing cost of the substrate module can be decreased.

Provided are a chip component mounting structure and a chip component mounting method, wherein when a plurality of chip components having different heights are mounted on a substrate via an anisotropic conductive film, position gaps which occur when the chip components are pressure-bonded to the substrate are prevented, and the chip components can be accurately mounted to the substrate at target positions; and a liquid crystal display device provided with the substrate. In the chip component mounting structure, a position fixing resin (4) for maintaining the orientation of chip components (2) which are pressure-bonded to a substrate (1) via an anisotropic conductive film (7) is provided. In the chip component mounting method, after the position fixing resin (4) for maintaining the orientation of the chip components (2) which are mounted to the substrate (1) via the anisotropic conductive film (7) is applied to the substrate (1) and cured, the chip components (2) are heated at a predetermined temperature and pressed at a predetermined pressure via an elastic sheet (5) provided on the chip components (2) and, then, pressure-bond to the substrate (1) together. The liquid crystal display is provided with such a substarate.

An aluminum alloy material for the shutter of flat recording medium cassettes. The shutter is light in weight and smoothly slidable, has good corrosion resistance and durability, and protects itself against staining with fingerprints. The aluminum alloy contains 3.0-6.0% Mg (by weight) and one or more than one optional elements of Mn.ltoreq.1.5%, Cr.ltoreq.0.3%, Cu.ltoreq.0.5%, and Ti.ltoreq.0.1%, with the balance being aluminum and inevitable impurities, and has a tensile strength of 310-410 MPa and a yield strength of 250-370 MPa. The aluminum alloy material is formed from a rolled sheet of said aluminum alloy by coating the sheet with a plastic film not thicker than 5 .mu.m. The rolled sheet undergoes intermediate annealing at higher than the recrystallization temperature, final cold rolling, and stabilizing heat treatment.
