I am looking to see what people are using for a min-max range to supply your PCB fabricators regarding solder mask thickness.

I saw some points in the archives but not too much regarding what people are providing as their spec ?

Any help would be appreciated.

Thanks.

Just out of curiosity - what is the rationale behind specifying mask thicknes?

Our company has a spec on their current PCB dwg to make sure the fab house meets a specific thickness (min-max). The current spec reads: 13.5um min - 38.5um max.

I assume it is to keep the board house honest and to make sure there is no exposed copper.

Excessive mask thickness also can wreak havoc on stencil printing.
