Abstract
Abstract Injection molded insulating strips receive a plurality of contacts. The strips are stacked together to create a multiple row, multiple column contact array. The contact array is adapted for use in an IC socket to separably connect an IC having either an LGA or BGA package lead styles. A cover plate, locator, array frame, and contact array together comprise a manufacturable and low cost separable IC socket.
