Abstract
Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.
