Abstract
The invention is an improvement in a carrier of the type used for testing circuit boards in an environmental test chamber. The improvement includes a plurality of frame-supported, spaced-apart shelves. Pairs of shelves are used to hold circuit boards being tested. The position of at least one shelf in such a pair is adjustable to select the proper dimension to support circuit boards of any of several particular sizes. In a highly preferred arrangement, shelves are arranged in two groups. At least one of the two or more shelves in each group is adjustable so that the carrier simultaneously accommodates circuit boards of differing sizes for test. Arrangements are shown whereby circuit boards of varying heights and/or lengths can be mounted in the carrier for simultaneous testing.
