  2. Printed circuit board - Wikipedia

    en.wikipedia.org/wiki/Printed_circuit_board

    When a PCB has no components installed, it is less ambiguously called a printed wiring board (PWB) or etched wiring board. [18] However, the term "printed wiring board" has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). In informal ...

  3. Wave soldering - Wikipedia

    en.wikipedia.org/wiki/Wave_soldering

    The Restriction of Hazardous Substances Directive (RoHS) has led to an ongoing transition away from 'traditional' leaded solder in modern manufacturing in favor of lead-free alternatives. Both tin-silver-copper and tin-copper-nickel alloys are commonly used, with one common alloy (SN100C) being 99.25% tin, 0.7% copper, 0.05% nickel and <0.01% ...

  4. Component placement - Wikipedia

    en.wikipedia.org/wiki/Component_placement

    Component placement is an electronics manufacturing process that places electrical components precisely on printed circuit boards (PCBs) to create electrical interconnections between functional components and the interconnecting circuitry in the PCBs (leads-pads). The component leads must be accurately immersed in the solder paste previously ...

  5. Printed circuit board milling - Wikipedia

    en.wikipedia.org/wiki/Printed_circuit_board_milling

    A milled printed circuit board. Printed circuit board milling (also: isolation milling) is the milling process used for removing areas of copper from a sheet of printed circuit board (PCB) material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file.

  6. Via (electronics) - Wikipedia

    en.wikipedia.org/wiki/Via_(electronics)

    A via (Latin, 'path' or 'way') is an electrical connection between two or more metal layers of a printed circuit boards (PCB) or integrated circuit. Essentially a via is a small drilled hole that goes through two or more adjacent layers; the hole is plated with metal (often copper) that forms an electrical connection through the insulating layers.

  7. Chip on board - Wikipedia

    en.wikipedia.org/wiki/Chip_on_board

    The PCB of a quartz watch. The clock IC is under the drop of black epoxy. Chip on board (COB) is a method of circuit board manufacturing in which the integrated circuits (e.g. microprocessors) are attached (wired, bonded directly) to a printed circuit board, and covered by a blob of epoxy. [1]

  9. Occam process - Wikipedia

    en.wikipedia.org/wiki/Occam_process

    The Occam process is a solder-free, Restriction of Hazardous Substances Directive (RoHS)-compliant method for use in the manufacturing of electronic circuit boards developed by Verdant Electronics. It combines the usual two steps of constructing printed circuit boards (PCBs) followed by the population process of placing various leaded and non ...
