   Pad — connects each end of the barrel to the component, plane, or trace; Antipad — clearance hole between barrel and metal layer to which it is not connected; Raspberry Pi Pico with castellated holes. A via, sometimes called PTV or plated-through-via, should not be confused with a plated through hole (PTH).

3. Microvia - Wikipedia

   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.

5. Via fence - Wikipedia

   en.wikipedia.org/wiki/Via_fence

   A via fence consists of a row of via holes, that is, holes that pass through the substrate and are metallised on the inside to connect to pads on the top and bottom of the substrate. In a stripline format both the top and bottom of the dielectric sheet are covered with a metal ground plane so any via holes are automatically grounded at both ends.

6. Teardrop (electronics) - Wikipedia

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

   Structural integrity may be compromised, e.g., by misalignment during drilling, so that too much copper may be removed by the drill hole in the area where a trace connects to the pad or via. [ 2 ] [ 3 ] [ 5 ] An extra advantage is the enlarging of manufacturing tolerances, making manufacturing easier and cheaper.

7. List of VIA chipsets - Wikipedia

   en.wikipedia.org/wiki/List_of_VIA_chipsets

   VIA chipsets support CPUs from Intel, AMD (e.g. the Athlon 64) and VIA themselves (e.g. the VIA C3 or C7).They support CPUs as old as the i386 in the early 1990s. In the early 2000s, their chipsets began to offer on-chip graphics support from VIA's joint venture with S3 Graphics beginning in 2001; this support continued into the early 2010s, with the release of the VX11H in August 2012.
