Introduction
Accompany the growth of integrated infrastructure for big data and intelligence analytics, the requirement of high power large size integrated circuit (IC) package for data center plays a crucial role. Flip chip ball grid array (FCBGA) is the mainstream of this kind of application, no matter integrates the functions by system on a chip (SoC), multi chips module (MCM), fan-out (FO) or 2.5D. FCBGA has a substrate with chips flipped on it; high performance FCBGA (HFCBGA) is a subset of FCBGA, which specifies the FCBGA has a heat slug attached on the substrate include the types of stiffener ring only, one-piece cavity type, one-piece hat type, two-piece type (thermal lid + stiffener ring) and thermal lid only (DLA, direct lid attach). For high power application, e.g., hundred watts power dissipation, a heat sink on the top of the package for heat dissipation is the universal method for thermal design. At this situation, chip exposed design packages, include FCBGA and stiffener ring only HFCBGA, have the best thermal performance, due to minimize the thermal resistance between chips and heat sink. However, it makes chips loss the protection from lid and exposure to damage risk under any uncertain forces. Therefore, HFCBGA with a lid for chip protection becomes a popular choice.
