The manufacture of six sigma quality high density interconnects by use of tin-lead solder flip chip bumps has prompted the application of computational analysis tools to assist in establishing the significance of variations of the bumps. Analytical model results and finite element predictions of solder joint geometry were compared to measured data. The solder geometric data and independently established component and substrate warpage were combined to calculate interconnect manufacturability
