SMEMA
Surface Mount Equipment Manufacturers Association
SMEMA is an acronym for the Surface Mount Equipment Manufacturers Association.
In 1999 they merged with the IPC to form the IPC SMEMA Council.
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
In 1984 a group of North American capital equipment suppliers started their collaboration to develop the original SMEMA specification. No formal document was available until 1987.
Begin with the source’s own compact description: “SMEMA” is surface Mount Equipment Manufacturers Association. The dossier treats that line as a proposition to test through SMEMA, Surface and Mount, not as a finished interpretation.
Why this record matters
The phrase “surface Mount Equipment Manufacturers Association” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Mar 31, 2026. The linked authority identifier is Q7391145. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1999, 1984 and 1987.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
