摘要： A test contact fixture which uses a flexible printed circuit tape to make contact to the integrated circuit and to a rigid printed circuit board which is part of the test equipment. The flexible printed circuit tape is held tightly against a hardened steel support allowing extremely accurate alignment both horizontally and vertically. The mounting plate provides a ground plane so that each lead may easily be configured as a 50 ohm transmission line. Leads of the integrated circuit under test are held in contact with the conductive lines on top of the flexible printed circuit tape by externally applied pressure allowing extremely rapid loading and unloading of the fixture. The body of the integrated circuit is held clear of the contact surfaces allowing heat control fixtures to be used to control the temperature of the integrated circuit during testing.
