It is my understanding that these coupon are part of a test panel located on the scrap edges of the panel. What I am searching for is actual functional area of a production panel once it has been depanelized. With or without components populated. What size of coupon.

Take a look at figure 12-4 (14mm x 17.5mm) for A/B and figure 12-2 (14mm x 17.5mm) for A and B in Revision A. In Revision B I believe that these are defined in appendices now. Hope that helps.

I am searching for the size of that coupon. I know that the ROI has to have a clearance of 25.4 mm (100 thousands). However, I do not find the actual size of the coupon. I have always used a 1 square inch size. I would like ti verify that dimension.
