<div dir="ltr">Hi Long,<div><br></div><div>At ANFF-ACT Canberra we charge precious materials in sputter at a fixed rate of AUD1/nm thickness.</div><div>In my opinion charging the weight difference is not the most accurate way as targets tend to get consumed more in the central part and you have to change the target once the middle part of the material is fully consumed. This brings additional cost when buying a new target even though the olad target can be recycled. </div><div>Another factor to consider: in the last six months gold price went up dramatically so if it happens you need to change targets nowadays the prices are substantially higher than a year ago. </div><div><br></div><div>Regards,</div><div>Fouad Karouta</div><div><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif">Ex-Manager ANFF ACT Node</p>

Hi Everyone,
<div><br>
</div>
<div>Thanks for all the input. I have plenty to think about to decide which makes sense for us.</div>
<div><br>
</div>
<div>Thanks,<br>

<div>Heho,</div>
<div><br>
</div>
<div>In GNuLab, users log their deposition thickness (including pre-sputtering). They get charged by the Angstrom. I recalculate the price every time a new target is installed.
<br>
</div>
<div><br>
</div>
<div>Price/A=(Price of new target-reclaimed value old target) / (#Angstroms that came out of the old target).</div>

<div>Hope this helps,</div>

<div>At UHNF, each user owns their own sputtering target. We are currently considering a shared model for expensive targets like Au, Pt, etc. Does anyone have a reasonable way to estimate material usage vs something we can track so that we can charge
fairly? What approaches do y’all take to manage how expensive material is shared?</div>
