Flip chip process flow
Webmanufacturing processes of three materials used in the flip chip package -underfill, solder mask, and IC passivation -were analyzed to determine how variation in these processes could affect the adhesion characteristics of the flip chip package. The results of the research indicate that the current underfill material used in the flip chip WebThe conventional capillary flow underfill process involves fluxing, placing, and reflowing the flip chip, and dispensing the underfill along the sides of the chip. The underfill flows by capillary action to fill the area underneath the chip. …
