Flip-Chip Underfill: Materials, Process and Reliability

WebALPHA HiTech Underfills are one component, heat curable materials. The materials have been optimized for capillary underfill and reworkability. These epoxy based materials can be dispensed on the edges of the BGA, CSP or Flip Chip devices. This material will subsequently flow to fill the space beneath these components. WebUnderfills are an insulating material designed to flow under flip chip devices to reinforce bumps and mounting board. The use of underfill for flip chips and reinforcement materials on CSP/BGA has increased rapidly as applications and reliability requirements have become more diversified. darts death
