Patent number: 7479795Abstract: A temperature control apparatus includes a socket holder which is provided on a tester head and holds a socket to mount an IC chip. A socket cover has an opening to pass the end of a handler pusher for holding the IC chip on testing. The socket cover forms a closed space around the IC chip in a state that the IC chip is pressed to the socket by the pusher. A gas supplying unit externally supplies the closed space with gas of a predetermined temperature.Type: GrantFiled: May 2, 2006Date of Patent: January 20, 2009Assignee: Daytona Control Co., Ltd.Inventors: Shintaro Hayashi, Osamu Urakawa, Mitsuo Koizumi

Patent number: 7214072Abstract: A pusher of an IC chip handler has a pusher frame which is attached to a pusher main body to be driven by the IC chip handler and a plurality of pusher heads attached to the pusher frame. Each of the pusher heads comprises a holder which is held by the pusher frame. At least one spring post is freely protruded outward from the inside of the holder, and a compression spring has one end arranged under pressure to a spring receiving portion of the spring post. A spring push plate arranges the compression spring to the spring receiving portion of the spring post under pressure, and an adjusting member adjusts a compression force of the compression spring. A device holding unit is attached to an end of the spring post protruded outside of the holder.Type: GrantFiled: October 31, 2005Date of Patent: May 8, 2007Assignee: Daytona Control Co., Ltd.Inventors: Shintaro Hayashi, Osamu Urakawa, Mitsuo Koizumi
