IPC 7094A describes the design and assembly challenges for implementing flip chip technology in a direct chip attach (DCA) assembly. The effect of bare-die or die-size components in a flip chip format has an impact on component characteristics and dictates the appropriate assembly methodology. This standard focuses on design, assembly methodology, critical inspection, repair and reliability issues associated with flip chip and die-size package technologies, including wafer-level ball grid array (WLBGA).
