電子回路基板 3Dモデル

Description A case for an electronic circuit board mounted with electronic components having a case main body whose one end is opened, an opening formed at an outer periphery of the open end of the case main body; and retaining means such as rails, projections, recess for retaining the electronic circuit board inserted through the open end at a prescribed position in the case main body. Texture All textures are 4096x4096. History The electronic circuit board can be immobilized at the prescribed position in the case main body and the strength of the case (i.e. case main body), particularly the strength of the open end thereof, can be increased. Moreover, when resin is potted in the case main body, any resin that runs out from the open end can be caused to flow into the opening.A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. It is also referred to as printed wiring board (PWB) or etched wiring board. A PCB populated with electronic components is a printed circuit assembly (PCA), also known as a printed circuit board assembly (PCBA).PCBs are rugged, inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire-wrapped or point-to-point constructed circuits, but are much cheaper and faster for high-volume production. Much of the electronics industry"s PCB design, assembly, and quality control needs are set by standards that are published by the IPC organization.An electronic circuit is a closed path formed by the interconnection of electronic components through which an electric current can flow. The electronic circuits may be physically constructed using any number of methods. Breadboards, perfboards or stripboards are common for testing new designs. Mass-produced circuits are typically built using a printed circuit board (PCB) that is used to mechanically support and electrically connect electronic components.Electronic circuits can display highly complex behaviors, even though they are governed by the same laws of physics as simpler circuits.Electronic circuits can usually be categorized as analog, discrete, or mixed-signal (a combination of analog and discrete) electronic circuits.
