Specifying certain text items for a board to be "in clad" means that the text should be made of copper, not silkscreen. Clad: A copper object on a printed circuit board.
Underneath that glob (technical term: glob top ), is a chip with fine wires bonded to both it and the landing pads on the board. The electronics for many mass-produced toys are embedded by this system, which can be identified by the black glob of plastic sitting on the board. Chip on Board: In this technology, integrated circuits are glued and wire-bonded directly to printed circuit boards instead of first being packaged. This technique is used to enhance transparency of multiple layers. Pads are represented as circles and thick traces as rectangular outlines instead of filled-in artwork. Check Plots: Pen plots that are suitable for checking only. Capture: Extract information automatically through the use of software, as opposed to hand-entering of data into a computer file. Often employed to enable a daughter or add-on card. Card-Edge Connector: A connector which is fabricated as an integral portion of a printed circuit board along part of its edge. Card: Another name for a printed circuit board.
Some PCB design software companies refer to all plotter or printer files as CAM file, although some of the plots may be check plots which are not used in manufacture. They are handed off to the board house which further refines and manipulates CAM data in their processes, for example in step- and-repeat panelization. CAM files represent the valuable final product of PCB design. The types of CAM files are 1) Gerber file, which controls a photoplotter, 2) NC Drill file, which controls an NC Drill machine and 3) fab and assembly drawings in soft form (pen-plotter files). These are the data files used directly in the manufacture of printed wiring. (See CAM files) CAM Files: CAM means Computer Aided Manufacturing. In electronics work, CAE refers to schematic software packages.
In electronics, the result would be a printed circuit layout. A system where engineers create a design and see the proposed product in front of them on a graphics screen or in the form of a computer printout or plot. Body: The portion of an electronic component exclusive of its pins or leads. A manufacturer of printed circuit boards. Also, a CAD database which represents the layout of a printed circuit. Assembly House: A manufacturing facility for attaching and soldering components to a printed circuit. Assembly Drawing: A drawing depicting the locations of components, with their reference designators (q.v.), on a printed circuit. PCB Glossary of Terms Analog Circuit: A circuit in which the output varies as a continuous function of the input, as contrasted with digital circuit.
