| Abstract |
As the demand for flip chip products increases, the need for high volume, low cost manufacturing processes also increases. Currently solder paste printing is the solder deposition method of choice for device pitches down to 200 ㎛. However limitations in print quality and solder paste volume mean that this technology is not likely to move below this pitch. This paper provides transformation method of flip chip solder bump manufacturing using Si carrier. 150 ㎛ solder bump was formed by this method. |
