WebJun 4, 1999 · These I/O bumps have to be placed under the following constraints: 1. minimize impact to the die size. This requires understanding the I/O cell area on the … WebSolder bumps (3% Sn, 97% Pb) on the die surface are joined with solder pads (60% Sn, 40% Pb) on the organic substrate in a reflow furnace. These joints form the electrical/ mechanical connection between the FC die and the OLGA package. An epoxy underfill fills the gap between die and the substrate.
