<div>Coral registers the amount of nm deposited and charges it back to the user at a rate around 1.5CAD/nm.</div>
<div>Weighting before and after is too complex as Fouad mentioned.</div>
<div>Dealing with user-owned target or material is also something we don’T want to get into.</div>

target that requires venting the sputter chamber. Also with a sputter system you end with an unusable part of the gold as it erodes unevenly and you end up with a significant amount of scrap.<o:p></o:p></span></div>
