Test system and test contactor for electronic modules

A pass through test contactor for testing an electronic module having a plurality of terminal contacts comprising:

• a base movable from a first position to a second position;
• a plurality of spring contacts on the base configured to electrically engage the terminal contacts and movable from the first position to the second position, each test contactor comprising a coiled spring and a terminal portion configured to electrically engage a terminal contact with a spring force generated by the coiled spring and with a zero insertion force on the module;
• and
• a flex circuit in electrical communication with the spring contacts.

A test system for testing an electronic an electronic module having a plurality of terminal contacts comprising:

• a test circuitry configured to apply test signals to the module;
• a board;
• and
• a plurality of coiled spring contacts on the board movable from a first position in which the terminal contacts can be aligned with the coiled spring contacts with a zero insertion force on the module, to a second position in which the coiled spring contacts electrically engage the terminal contacts, each coiled spring contact comprising an end portion in electrical communication with the test circuitry and a tip portion configured in the first position to be spaced from a terminal contact and in the second position to electrically engage the terminal contact.

A system for testing an electronic module having a plurality of terminal contacts comprising:

• a test circuitry;
• a test handler;
• a board on the test handler;
• a base on the board movable by the test handler from a first position to a second position;
• and
• a plurality of test contactors on the base in electrical communication with the test circuitry configured to electrically engage the terminal contacts, each test contactor comprising a coiled spring having a terminal portion configured to align with a terminal contact in the first position and to electrically engage the terminal contact in the second position with a spring force exerted by the coiled spring.
