Carrier module for use in a handler and handler for handling packaged chips for a test using the carrier modules

A carrier module comprising:

• a body;
• a base plate, in which a plurality of packaged chips are placed in substantially a same direction, provided to the body, and
• at least one latch having a first bar which is commonly disposed across and in contact with surfaces of at least two adjacent packaged chips to hold the packaged chips in position on the base plate, wherein the first bar of the latch has a linear section which extends across and in contact with the surfaces of the at least two adjacent packaged chips to hold the at least two adjacent packaged chips in position on the base plate at a same time, and wherein the linear section which contacts the surfaces of the at least two adjacent packaged chips extends substantially in a same plane parallel to surfaces of the at least two adjacent packaged chips;
• and wherein the first bar includes a plurality of additional sections spaced from one another, each additional section extending from the first bar to contact respective ones of the at least two adjacent packaged chips, the additional sections providing additional forces for holding the at least two adjacent packaged chips in position on the base plate.
