These functions are achieved through the use of a variety of components. Common components include surface-mount components and plug-in components. To ensure the placement of plug-in components, the circuit board requires multiple through-holes that penetrate the front and back of the board. Finally, the components are soldered using processes such as wave soldering.

Existing technology is prone to the following issues: The through-hole diameter does not match the component pins or span, resulting in an interference fit that makes component insertion difficult; and excessive clearance between the through-hole diameter and the pins, resulting in skew, floating, and misalignment of the through-hole peaks.
