摘要:
A method for wiring a test fixture comprised of two parallel fixture plates wherein the wires are wired randomly from locations on one plate to locations on a second plate using a system of software algorithms and positioning apparatus to control the motion of one plate relative to the other to allow the wires to be passed directly through the hole locations to be wired together, while previously woven locations are allowed to slide in the hole in the fixture plate to allow reaching subsequent hole pair locations. After the fixture is wired, a termination is added to the wire end emerging from the hole in the fixture plates. The resultant assembly consists of contacts on one outer surface electrically connected to contacts on a second outer surface with all of the wiring sandwiched between the two fixture plates.

A test module used to verify the correct placement of light-emitting devices on electronic assemblies, by performing color and luminous intensity tests on these devices. The module includes one or a number of color sensitive photodiodes, which when exposed to light coupled from the emitter under test, will accurately measure the intensity, as well as the true color emitted by the device. The test module outputs analog signals, one directly proportional to the intensity, a second voltage proportional to the spectral wavelength of the device under test.

A high speed, low mass positioning apparatus is provided for positioning a test probe or other like item at any desired point within an x-y plane. The apparatus comprises a first axis of movement mechanism for positioning the item along one axis of movement and a second axis of movement mechanism for positioning the item along the remaining transverse axis of movement. Both of the axis of movement mechanisms comprise motor driven pulley wheel and drive cable arrangements arrayed around the outer periphery of the x-y planar surface area within which it is desired to position a test probe, tool or other like item. A light inflexible track member is secured between and carried by two spaced-apart movable trucks and is movable therewith in either direction along the said one axis of movement. A small lightweight movable carrier is movably supported on the track member and is movable therealong in either direction. The remaining axis of movement mechanism is arranged to move the small lightweight movable carrier back and forth in either direction along the track member. One side of a movable fine wire loop is secured to and moved by the small lightweight movable carrier and a test probe or other like item is secured to and movable with the other side of the movable fine wire loop whereby the test probe or other item can be positioned at any desired point within the planar x-y surface area. The apparatus is designed to be mounted within the interior of a substantially airtight, environmentally controlled test chamber.
