Panel fiducials have offset
ISD found the issue that the fiducials on the PCB and soldermask have an offset.
The provided gerber file for the PCB panel (here attached) has 3 diamond shaped fiducials on each side of the panel. The issue is that the XY coordinates of the fiducials does not match the dimensions written on the panel:
- Fiducial 1 : X 7.5 Y 25.0
- Fiducial 2 : X 7.5 Y 218.9
- Fiducial 3 : X 198.2 Y 25.0
In cooperation with our PCB manufacturer the correct alignment has been achieved by following the written dimensions and not the gerber data for the fiducials; otherwise an offset is introduced. The PCB panel has been manufactured by following the written dimensions.
