A method for manufacturing a multi-piece board having a frame section and a multiple piece sections connected to the frame section includes forming a frame section from a manufacturing panel for the frame section, sorting out multiple acceptable piece sections by inspecting quality of piece sections, forming notch portions in the frame section and the acceptable piece sections such that the notch portions allow the acceptable piece sections to be arranged with respect to the frame section, provisionally fixing the piece sections and the frame section in respective positions, injecting an adhesive agent into cavities formed by the notch portions when the frame section and the piece sections are provisionally fixed to each other, and joining the acceptable piece sections with the frame section by curing the adhesive agent injected into the cavities.
Abstract:
An electronic circuit contains a circuit board with conducting tracks to which one or more electronic components with conducting contacts are positioned overlying portions of the conducting tracks and each such electronic component is held in place by a clamp that covers and is contact with the top surface of the electronic components so as to hold their conducting contacts in electrical contact with the conducting tracks of the circuit board. The clamp can include a resilient layer held between the top surface of electronic components and a rigid clamping sheet.
Abstract:
An optical module includes: a transparent substrate through which light can pass; a photoelectric conversion element mounted on the transparent substrate and emitting light toward the transparent substrate or receiving light having passed through the transparent substrate; and a support member supporting an optical fiber for transmitting light, the support member and the transparent substrate forming an optical path between the photoelectric conversion element and the optical fiber. A positioning hole is formed in the transparent substrate. A positioning pin having a tapered surface is formed on the support member. The transparent substrate and the support member are positioned with respect to one another by inserting the positioning pin into the positioning hole along the optical axis direction of light between the transparent substrate and the support member and by making the tapered surface of the positioning pin contact the edge of the positioning hole without leaving any space therebetween.
