Hello Brian,<br>
<br>
I have made the modifications as soon as possible as I am leaving on
vacation tomorrow (I didn't expect your last iteration to take so
long). Please review the design and tell me something by (my)
tomorrow because otherwise I will not be able to submit the mask for
fabrication until beginning of September.<br>
<br>
Regards,<br>
<br>
Miguel.<br>

<pre wrap="">Hi Miguel,
Sorry for the late reply, just finished a meeting with some of the physicists/engineers.
Last remaining issue they see is that the various sensor side pads aren't centered with respect to the other pads/traces.
Both of the bias pads on the sensor side need to move 34 (19 + the 25 from the next line) microns up and 385 microns towards the sensor pads.
The shorter sensor pads need to be moved 25 microns up.
Also the traces are not entering the pads on the same spots. They want those centered as well.
I've attached a zip file with an AutoCAD drawing showing the issues as well as some PNG images.
Let me know if you have any questions.
Thanks
Brian

<pre wrap="">Hi Brian,
I have not heard any news from you since I sent you the last design correction. Do you have any comments or I can go ahead with the mask fabrication?
Regards,
Miguel.
