    Assembly with thermocompression bonding (TCB) enables the next generation fine pitch 2.5D and 3D products using Cu pillar interconnects, but the industry has been slow to invest in the dedicated infrastructure required for the process. TCB volume today is driven primarily by the memory market and stacked DRAM packages, including the Hybrid Memory Cube (HMC) and High Bandwidth Memory (HBM) products; however, the extreme placement accuracies required for TC bonding can be leveraged to enable improved capability for other assembly processes as well. With only minor modifications, the same equipment used for TCB assembly can also be used for highly accurate die placement in Fan-out Wafer Level Packages (FOWLP) and die placement for mass reflow processes with pitches as low as 30um. The flexibility inherent in new tool designs ensures cost effective HVM capability for TCB as well a manufacturing platform with the ability to adapt to product mix changes over time. The same tool purchased for Flip Chip or FOWLP die placement today can be configured to run HVM TCB 2.5D or 3D later. This presentation will review the performance of this flexible manufacturing platform over a range of Advanced Packaging processes.
