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. WebThe underfill flows by capillary action to fill the area underneath the chip. Finally, a cure must be completed in an oven. No-flow underfill processing uses fluxing underfills that are dispensed onto the substrate before flip chip placement. The chip is placed onto the dispensed underfill, causing squeeze flow of the material.
