It is specifically capable of:

* handling very thin wafers with unusual topography
* able to accomodate that topography being inverted by providing a custom chuck
* laying down a redistribution layer and underbump metalization at one time using one mask
* attaching bumps of virtually any size on any pitch required (down to 70 u bumps on 140 u pitch)
* making large solder balls as well as small solder balls
* VOID-less solder bump attachment
* fabricating custom sized solder balls on custom pitches
With this process you are not constrained to the standard solder ball sizes. The technology handles lead-less alloys as well as leaded alloys. High lead content is also not a problem.
