The ASM AFC Plus is a fully automatic flip chip bonding system designed for advanced semiconductor packaging processes requiring high-precision die placement, fine-pitch interconnect formation, and stable thermomechanical bonding control.
It is commonly deployed in OSAT and IDM environments transitioning toward heterogeneous integration, where electrical performance and I/O density exceed the limits of conventional wire bonding and epoxy die attach.
Core Function
The system performs flip chip die attachment by placing bumped dies onto organic substrates, silicon interposers, or ceramic carriers. It integrates alignment, flux control, and thermal bonding into a single automated process chain.
Depending on configuration, the platform supports both mass reflow and thermocompression bonding (TCB) for advanced interconnect formation.
Key Technology Modules
Vision Alignment System: Sub-micron optical recognition compensates for die shift, substrate warpage, and pad misalignment.
Flux Control Unit: Ensures uniform flux coverage for stable solder wetting and reduced void formation.
Bond Force Control: Closed-loop force regulation prevents bump collapse and improves mechanical reliability.
Thermal Management System: Dynamic heating profiles optimized for SnAg and AuSn interconnect systems.
