发明名称 Substrate with bond fingers
摘要 A flip chip mounting board includes a substrate having a top surface and a plurality of generally parallel, longitudinally extending, laterally spaced apart bond fingers are formed on the top surface. Each of the plurality of bond fingers has a first longitudinal end portion and a second longitudinal end portion. A first strip of laterally extending solder resist material overlies the first longitudinal end portions of the bond fingers. The first strip has an edge wall with a plurality of longitudinally projecting tooth portions separated by gaps with a longitudinally extending tooth portion being aligned with every other one of the bond fingers. Adjacent bond fingers have first end portions covered by different longitudinal lengths of solder resist material.
