        In case you need generate 3D pdf ( <a href="http://www.voipac.com/downloads/imx/53/doc/iMX53_SODIMM_3D.pdf">like this iMX53 SODIMM 3D pdf</a> where you can click and see the board from every angle), use for example <a href="http://help.adobe.com/en_US/Acrobat/9.0/3D/WS58a04a822e3e50102bd615109794195ff-7c13.w.html">Adobe 3D Reviewer</a>. How? Export your PCB from Altium Designer into STEP file and open it in the Adobe software. Then File -> Export will save it into 3D PDF file. Disadvantage – Adobe 3d Reviewer is not FREE.

        PCB manufacturer normally provides information about PCB stackup and track geometry.<br><br>

        In case you need to calculate single ended or differential pair impedance on your PCB, try following links:<br><br>
