Underfill Technology

01/01/2000

The "No Flow-Fluxing" underfill is designed to help manufacturers and assemblers of area-array devices, such as flip chip, CSP and BGA, reduce the overall cost of device assembly. This technology reportedly eliminates separate fluxing, flux cleaning, underfill capillary flow and post-cure operations using underfill in area-array device assembly because the underfill performs the dual role of fluxing the interconnects and curing to become the underfill layer.
