With the advancement of stacked 2.5D and 3D packages and wafer-level packaging, assembly processes including molding have been challenged. Dies with fragile features and interconnect wires as small as 0.5 mil diameter have become incompatible with transfer molding, which uses high injection pressures to push melted thermoset resin through tiny channels and gates to fill up cavities.
The fact is these advanced packages, wafers and panels have limited space for resin flow. Wafer-level packaging and molding of large-wafer- and large-area-size substrates (Panel Mold) are limited by current transfer mold technology.
To solve these issues, Compression Molding was developed and introduced by Towa as early as 2005. Compression molding is a process which allows the slow "dipping" of the devices into either a melted granular or liquid mold compound. Package quality and process parameters are inherently improved and some reliability results will be presented. Compression molding technology allows the advancment of innovative advanced package structures and scalability.
