  2. 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.

  3. Printed circuit board - Wikipedia

    en.wikipedia.org/wiki/Printed_circuit_board

    A printed circuit board (PCB), also called printed wiring board (PWB), is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive ...

  4. 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 ...

    The codes given in the chart below usually tell the length and width of the components in tenths of millimeters or hundredths of inches. For example, a metric 2520 component is 2.5 mm by 2.0 mm which corresponds roughly to 0.10 inches by 0.08 inches (hence, imperial size is 1008).

  6. Eurocard (printed circuit board) - Wikipedia

    en.wikipedia.org/wiki/Eurocard_(printed_circuit...

    Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.

  7. Microvia - Wikipedia

    en.wikipedia.org/wiki/Microvia

    The ANOVA results showed that the strain concentration factor was the most important variable, followed with the ductility factor, metallization thickness, and via wall angle. Prabhu et al. [ 10 ] conducted a finite element analysis (FEA) on an HDI microvia structure to determine the effect of accelerated temperature cycling and thermal shock.

    Anyone watching the news following the presidential election has heard one word associated with President-elect Donald Trump more than any other: tariffs. Tariffs are taxes levied upon foreign ...

  9. Through-hole technology - Wikipedia

    en.wikipedia.org/wiki/Through-hole_technology

    Through-hole (leaded) resistors. In electronics, through-hole technology (also spelled "thru-hole") is a manufacturing scheme in which leads on the components are inserted through holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side, either by manual assembly (hand placement) or by the use of automated insertion mount machines.
