The chip module includes a substrate and a chip disposed on the substrate. The first clamping member defines a recess and a contact portion around the recess. The chip is received in the recess, and the contact portion abuts the substrate. A second clamping member abuts the second side of the circuit board. A plurality of stress adjusting members extends through the second clamping member and engages the first clamping member.
