A printed circuit board can be used as a test card. The printed circuit board has a first image and a second image. The first image includes a first array pattern for attaching a package, a first power plane, and a first ground plane. The second image includes a second array pattern for attaching a package, a second power plane, and a second ground plane. A first routing area between the first image and the second image electrically and physically isolates the first power plane from the second power plane. The first routing area also physically isolates the first ground plane from the second ground plane. A first single trace extends through the first routing area. The first single trace electrically connects the first ground plane to the second ground plane.

Versatile printed circuit board for testing processing reliability

An interconnect adapter is used in operational environment testing of a printed circuit assembly unit. The interconnect adapter includes a main base assembly, a probe plate assembly and an engagement unit. The main base assembly includes an attachment structure for attaching the printed circuit assembly unit to the main base assembly. The printed circuit assembly unit, when attached to the main base assembly, is in position to be connected to a host device. The probe plate assembly is attached to the main base assembly and includes pins for electrical connection to test points for an integrated circuit on the printed circuit assembly unit. The engagement unit is for engaging the pins of the probe plate assembly in position to make electrical connection with the test points.
