PMP41115: Issue with Gerber data in reference design files

Part Number: PMP41115


Tool/software:

I've encountered an issue with the PCB fabrication data provided with this reference design. There is a difference between the board stackup shown in a table on layer GM12 and the design information on layer GM10.

 

  • The board stackup indicated by the table (in red below) in the upper right corner of GM12, implies a stackup of 40.8mil (1.22mm).
  • The “Design Information” on Layer GM10 indicates a thickness of 62mil (1.6mm), which is typical.
  • The Stackup Manager in the Altium design file indicates an overall thickness of 1.03632mm.

 

Is there an issue with the stackup information?
