The manufacturability of these connectors has been evaluated and documented previously; however, there is a need to study the second-level reliability of these connectors. This paper will focus on the reliability data generated from the accelerated thermal cycling of the "Metropolis" test vehicle, which was performed using IPC-9701 as a guideline. The "Metropolis" test vehicle incorporates two styles of BGA mezzanine connectors, a BGA mounted socket, and press fit connectors.
In addition, assembly results related to a lead free version of one of the press fit connectors have been studied, and reliability data for this connector will be generated. None of the other connectors studied was available at the time of assembly in a lead free version - they will be included in future projects once they are available.
Key words: BGA Connectors, Press Fit Connectors
