cMaximum depth of 0.002 inch (0.05 mm) and minimum radius of 0.5 inch (12.7 mm) are required.
NOTE:
These are only maximum and minimum requirements, the recommendation is to polish a smoother surface to avoid probe uneven contact.

bCoverage must be a minimum of 125 percent.
cAn intensity verification is necessary with a simulative fixture.
dUse C04-166  CCW14 cut wire shot.
eIntensity must be 0.006-0.012N.
fOverspray is permitted.
