Abstract: An automated circuit board tester comprises an unstacker (1) arranged upstream of a testing device and which by means of a circuit board picker (40) arranged above a chute (30) picks a top-most circuit board from a stack of circuit boards (55) located in the chute (30). The chute (30) comprises a lifting device including at least two sets of vertically travelling supporting elements (38, 101), each of which is able to carry a stack of circuit boards (55). The chute (30) is open at least on one side so that a set of supporting elements (38, 101) can be loaded while a stack of circuit boards (55) located on the other set of supporting elements (38, 101) is unstacked by the circuit board picker (40).

Abstract: An apparatus for storing and transporting printed circuit boards is disclosed. The apparatus comprises a body having a base defining an upwardly facing support surface for supporting a stack of printed circuit boards. The support surface may optionally have a slight rearward inclination. Elongate annular members are secured to the base on both sides and extend adjacent to the supporting surface and remotely therefrom in the direction in which the stack of printed circuit boards is to be arranged. Liners are provided with holes through which the annular members extend so that the liners are movable between a suspended stand-by position to an operative position in which the liners are horizontally supported on or are vertically suspended between adjacent printed circuit boards. Two symmetrically arranged synchronized belt drives are mounted on the base and comprise belts extending parallel to elongate annular members.
