Internal details of a two head, gantry style pick-and-place JUKI SMT machine. In the foreground are tape and reel feeders, then the (currently empty) conveyor belt for printed circuit boards, and in back are large parts in a tray. The gantry carries two pickup nozzles, flanking a camera (marked "do not touch" to avoid fingerprints on the lens).
SMEMA is an acronym for the Surface Mount Equipment Manufacturers Association.. In 1999 they merged with the IPC to form the IPC SMEMA Council. [1]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.
A pick and placement machine is a robotic style machine that places some variety of types of components. It includes features such as: component pickup feeder locations, vacuum pickup, vision system, automatic component realignment, repeatable placement accuracy, and transportation system for PCBs.
High volume production is usually done with a pick-and-place machine and bulk wave soldering for through-hole parts or reflow ovens for SMT components or through-hole parts, but skilled technicians are able to hand-solder very tiny parts (for instance 0201 packages which are 0.02 in. by 0.01 in.) [29] under a microscope, using tweezers and a ...
The components to be placed on the boards are usually delivered to the production line in either paper/plastic tapes wound on reels or plastic tubes. Some large integrated circuits are delivered in static-free trays. Numerical control pick-and-place machines remove the parts from the tapes, tubes or trays and place them on the PCB. [7]
Pick and place is the act of picking things up from one location and placing them in another. Specific cases include: picking and placing is one of the major uses of industrial robots; in the context of electronics, SMT placement equipment
While generally not considered to be a machine element, the shape, texture and color of covers are an important part of a machine that provide a styling and operational interface between the mechanical components of a machine and its users. Machine elements are basic mechanical parts and features used as the building blocks of most machines. [2]
A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional ...
