TIDA-00281: PCB Layer structure

John Pan

Part Number: TIDA-00281

Hi,

I have a question on the layer structure (stack up) for TIDA-00281 (TIDUAY9). In page 85, Section 8.3.2, it said "This design uses a 6-layer board." But the Figure 126 only shows 4 layers, which are Top layer, Internal Plane (Ground), Signal Layer 3, and Bottom Layer. Could you please point me out the other two layers? or it was a typo and should be "This design uses a 4-layer board."

Thanks,

John

Hi, John,

You can view all the layers in the Gerber files. They are posted on our website here:

Hi Don,

Thank you very much for your quick reply. I am only able to find two Gerber Cu layers, Signal (layer 3) and bottom. It seems that the ground (layer 2) and the top layer Geber files are missing. It seems it is a 4-layer board design, not a 6-layer board design as documented in the reference TIDA-00281.

Could you please check?

Thanks,

John
