2. 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 ...

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. 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.
