翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク SMEMA ： ウィキペディア英語版 SMEMA SMEMA is an acronym for the Surface Mount Equipment Manufacturers Association. In 1999 they merged with the IPC to form the IPC SMEMA Council.〔From Vacuum Tubes to Nanotubes: An Amazing Half Century, Published by the IPC, Edited by Michael L. Martel〕 One standard they have is for the wiring of communications between Surface mount technology producing machinery such as a Stencil Printer or a Pick and Place Machine on an Electronics production line. This allows the machines including the "bridges" between the two known simply as conveyors to communicate that they are busy, or awaiting a circuit board. The communication only goes sequentially as there is no addressing. Instead the machine's SMEMA cables connect to each other's upstream or downstream plug. The plugs and wires are multimate connectors and receptacles consisting of 14 wire connections. However, only 4 wires are used for data, while the 8th pin connection is the shielding. ==History== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SMEMA」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
