  2. 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.

  3. 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 ...

  4. Microvia - Wikipedia

    en.wikipedia.org/wiki/Microvia

    The HDI layers are built on both sides of the traditional PCB one by one with microvias. The SBU process consists of several steps: layer lamination, via formation, via metallization, and via filling. There are multiple choices of materials and/or technologies for each step. [3] Microvias can be filled with different materials and processes: [4]

  5. 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 ...

  6. 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 ...

  7. Coupon (PWB) - Wikipedia

    en.wikipedia.org/wiki/Coupon_(PWB)

    A coupon or test coupon is a printed circuit board (PCB) used to test the quality of a printed wiring board (PWB) fabrication process. Test coupons are fabricated on the same panel as the PWBs, typically at the edges. Coupons are then inspected to ensure proper layer alignment, electrical connectivity, and cross sectioned to inspect internal ...

  8. Circuit design - Wikipedia

    en.wikipedia.org/wiki/Circuit_design

    The process usually begins with the conversion of the specification into a block diagram of the various functions that the circuit must perform, at this stage the contents of each block are not considered, only what each block must do, this is sometimes referred to as a "black box" design. This approach allows the possibly highly complex task ...

  9. Routing (electronic design automation) - Wikipedia

    en.wikipedia.org/wiki/Routing_(electronic_design...

    In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement, which determines the location of each active element of an IC or component on a PCB.
