Abstract:
A test system for testing units of an electronic device, the test system comprising:at least one test head; at least one load board for receiving a unit of the electronic device, each load board having a pattern of test-head signal transmission positions largely identical to the pattern of test-head signal transmission positions of each other, if any other, load board; a probe system having a probe; and an interface apparatus, the test system being deployable (a) in a direct configuration in which one such load board is directly attached to one such test head for transmitting test signals through that load board's test-head signal transmission positions and (b) in an interface configuration in which one such load board is coupled through the interface apparatus to one such test head for transmitting test signals through that load board's test-head signal transmission positions, in which the probe system contacts the interface apparatus or/and load board, and in which the interface apparatus is configured to largely prevent vibrations in that test head from being transferred through the interface apparatus to the probe system.
