A cover is operable to seat and unseat electronic components. In a preferred embodiment, a tertiary amine is added to a polyorganosiloxane coating composition to achieve an improved abrasion coating. A mixer forms the product of the combined signal and the quadrature signal to produce a baseband output signal. The stacked main body also has a predetermined suspended portion. The secondary lock has lock nibs that engage internal partition walls of the connector body to hold the secondary lock in a preload position that permits insertion of the electrical terminals into the terminal cavities via openings at the insertion end of the connector body. The method comprises: translating sales specific terminology describing end products into bill of material terminology describing parts used in end products via a bill of material structure; and, utilizing the bill of material structure, determining an optimal build plan for end items that, if built, would consume a desired quantity andor type of excess inventory.
