> * Improved registration (front-to-back & across a side) - mainly due
> to some cunning CCD camera alignment system. Registration will be
> particularly important when LDI soldermask comes to market, as this should
> mean that all your solder dams will now be nicely aligned with those high
> I/O SMT/ BGA/ etc packages.
> * Artwork scaling to fit fiducial marks (within reason) - compensates
> for 'movement' during lamination.
> * Removal of artwork creation stage, also removes any repeat defects
> from artwork faults.
> * Creation of image 'in software' means that jobs can be run through
> imaging in any order - saves time in changing/ alignment of standard
> phototools.
> * Improved resolution is also sometimes quoted, but not so sure
> whether this is a feature of the LDI or just that the yields on <100µm
> (4mil) lines are improved due to the other benefits I've listed.

> If you need further detail, I really will have to refer you to the
