LDC0851 Coil Design

HJ Lim
Prodigy 80 points

I exported a CAD design thru the URL below.

http://webench.ti.com/wb5/LDC/#/spirals?origin=pf_panel&lang_chosen=en_US&partno=LDC0851&shape=Circular&lcTanKCapacitance=68&layers=4&spaceBetweenTrace=6&traceWidth=6&copperThickness=1.000&temperature=25&voltage=1.8&x12=8.00&x34=8.00&dout=1574.&x23=36.6&turns=40

But the data is broken.

There are only 3 layers and I cannot find the forth layer.

Is this a bug? or problem of environment? Currently I'm using PADS Layout 9.5.

    Hello,

    I see the same issue with the PADS export:

    It looks like there are a few errors from the import log:

    If you export to Altium it works fine:

    We will move this thread to the Webench forum.

    Thank you for finding this!

    Hi Luke,

    For PADs, couple of the layers are defaulted to black color so it's hard to tell if the layers are there without reassigned the layer colors. Go to Setup menu and select  Display Color Setup. A new window will open and select Assign All button. Another new window will pop up and make sure the Automatically Make Object Visible is highlighted. The color preference is defaulted to One color for a layer and check both the boxes under it.   Click on OK, you should see all the layers.  Hope this helps.
