Hi Stella,
Relief etch the higher area. Provide the cad data file of the higher area to
your stencil vender and tell them you want a 0035m relief on the bottom side of
the stencil. This should correct your problem.

Hi,
Would like to know if  there is any recommendation on printing solder paste
onto 
exposed solder pads which the solder mask over bare copper is 3 mils higher
than 
the exposed solder pads?  Recently, we are attempting to print so but result in

solder shorts due to extra heights.
Appreciate any helpful info.

thanks
stella yap
