The proximity sensor includes a board; at least three light emitting portions which are mounted on a surface of the board such that not all the light emitting portions is arranged on a straight line, and which emits light; and a light receiving portion which is mounted on the surface of the board so as to have a predetermined positional relationship with the three light emitting portions, and which receives reflected light derived from light emitted from the light emitting portions and reflected by the object to be detected.
Abstract:
The present invention provides a component securing structure that forms a wiring unit on a TFT glass substrate that is capable of transmitting UV light. A component, such as a driver IC and/or an FPC, is electrically connected to the wiring unit and is secured to the TFT glass substrate by a UV-curable ACF. An opening for transmitting UV light is formed in a light shielding layer of the wiring unit. UV light irradiated from the back side of the TFT glass substrate passes through the opening and directly irradiates the UV-curable ACF.

Abstract:
The invention forms conductive tracks in electronics and microelectronics for the commutation of electronic circuits and semiconductor devices. The method for producing conductive tracks includes applying continuous metallization layers to a non-conductive substrate, forming a metallization pattern, and applying to the formed tracks a protective barrier layer and a layer for soldering and/or welding elements of parts to the conductive tracks. The continuous metallization layers are applied by consecutively applying an adhesive layer, a conductive layer, and a metal layer, acting as a mask, to the non-conductive substrate. To form the metallization pattern, a mask is formed by laser ablation on sections of the metal layer not occupied by conductive tracks, then selective chemical etching removes the conductive layer and adhesive sublayer from the exposed sections, and selective chemical etching removes the mask, after which the protective barrier layer and layer for soldering and/or welding are applied.
