ABSTRACT:
Double-faced detecting devices for an electronic substrate, the detecting device have a base and two probe-detecting machines oppositely located beside the base. The base has a guiding groove and a substrate platform with a through hole rotatably and movably mounted on the base via the guiding groove. Therefore, when the electronic substrate mounts on the substrate platform, the substrate platform enables to rotate from a horizontal position to a vertical position to expose two faces of the electronic substrate to face the two probe-detecting machines for a double-faced detection of the electronic substrate in high-frequency properties. Additionally, each probe-detecting machine is mounted on a pivot base and pivoted by the pivot base to adjust the height of probe to touch the electronic substrate at the vertical position.
