Fiducial check on White Soldermask Aluminum PCB's

[S G.]

Hi There,

First post here. Thanks for all the great work of everybody!

I have difficulties with the fiducial check on white soldermask aluminum PCB. With my green soldermask PCB's the fiducials are checked nicely without problems.

Does anyone have an idea how to proceed with white soldermasks? Any idea for the pipeline maybe?

Thanks...
