A press-fitting device in which a terminal of a connector having a staggered arrangement section of the terminal of the connector is press-fitted into an insertion hole is provided. A method for stitch bonding a pliant batt of intertwined fire-resistant fibers to form a fabric which is durable and resistant to unraveling is also provided. In the chip core region, a large number of circuits are arranged. The series chain starts with an initial scan chain and ends with the end scan chain. The inspection system of the present invention includes a socket of the present invention, and an evaluation board for connecting a third terminal of the socket electrically to the inspection apparatus of the electronic component, and propagating an inspection signal. In other words, very little space is required to implement this approach is hardware with nominal increase in power consumption, and this slight increase in power consumption provides a significant increase in ECC correction capability using this approach.
