Webthan lead based solders, which means that C4 bump reliability will become increasingly important in future IC designs. One method of addressing the solder bump reliability problem during IC design is to co-optimize the placement of bumps and the chip which will be the focus of this paper. The importance of chip package co-design are detailed in WebAug 10, 2024 · Move to C4 bumps and Cu pillars (a.k.a. C2), and height variation impacts the wafer probing process. With a 200-micron bump height, 10% variation in height directly impacts the overtravel needed during wafer probe. Decrease to 50-micron bump height, and that same 10% variation has a greater impact.

WebDie size and bump count are adapted to the connection requirements. Figure 2. Mechanical dimensions of a 4 x 2 bump matrix array (sample). Note: The package height of 290 µm is valid for a die thickness of 200 µm. The Flip Chip tolerance on bump diameter and bump height are very tight. This constant bump shape insures a good coplanarity ... 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.
