Abstract
A probe station for probing a test device has a chuck assembly substantially enclosed by an environment control enclosure and laterally movable relative to such enclosure. The environment control enclosure includes a flexible wall assembly interconnected with the chuck assembly to enable such lateral movement thereof along mutually perpendicular directions while maintaining the integrity of the enclosure. The flexible wall assembly has flexible pleats formed therein extending along respective different lateral directions to enable such lateral movement.

A probe station for probing a test device, said probe station comprising:
- (a) a chuck assembly having a laterally extending supporting surface for supporting said test device during probing thereof;
- (b) an environment control enclosure substantially enclosing said supporting surface, said chuck assembly being laterally movable relative to said environment control enclosure;
- (c) said environment control enclosure including a flexible wall assembly interconnected with said chuck assembly, said wall assembly comprising flexibly extensible and retractable material having multiple laterally extending flexible pleats formed therein in laterally offset relation to said chuck assembly, said pleats extending along respective different lateral directions to enable said wall assembly to flexibly accommodate movement of said chuck assembly in multiple lateral directions perpendicular to each other.
A probe station for probing a test device, said probe station comprising:
- (a) a chuck assembly having a laterally extending supporting surface for supporting said test device during probing thereof;
- (b) an environment control enclosure substantially enclosing said supporting surface, said chuck assembly being laterally movable relative to said environment control enclosure;
- (c) said environment control enclosure including a flexible wall assembly interconnected with said chuck assembly, said wall assembly comprising at least a flexibly extensible and retractable first wall element and a flexibly extensible and retractable second wall element, each wall element being extensible and retractable independently of the other along a respective lateral flexing axis substantially perpendicular to that of the other, said second wall element being movable along a direction transverse to its respective lateral flexing axis in unison with the flexing of said first wall element along its respective lateral flexing axis.
