Economical solution for accurate and repeatable production test docking

inTEST EMS 4-CAM docking systems have been an industry standard for more than 20 years. With an installed base of over 10,000 sets the reliability, repeatability, durability and ease of use of the inTEST EMS 4-CAM docking systems is well known. The robust linkage design makes the docking assembly virtually maintenance free for low cost of ownership.

With existing designs for 100’s of test systems, handlers and probers, the inTEST EMS 4-CAM docking system for your application is available today.

Key Features

Supports backward compatibility using a peripheral side docking plate with multiple docking and coarse alignment features
100% plug compatible with existing inTEST EMS test head docks for all common test systems
100% compatible with all existing calibration tools
Linkage system has been located on the bottom of the docking plate for a clean look and eliminates any pinch points
Precision design, manufacturing, and assembly assure accuracy to +/- 127 um (.005") in the X, Y, and Z-axis

Compatible Testers

The 4-CAM docking system can be used with all the most common test heads.


Linkage style test head docking

The Linkage Style test head docking replaces the traditional "Cable" style of connection with a robust direct linkage. The linkage design makes the docking assembly virtually maintenance-free for low cost of ownership.

All linkage docks are 100% backward compatible with existing inTEST EMS docking so that no changes are required to your existing handler or prober docking setups. And are compatible with inTEST EMS designed manipulator and test interface hardware for seamless MDI (Manipulator, Docking, Interface) integration.
