Fellow TechNetters:

  In IPC-TM-650 / 2.6.8 section 3.1 states a test coupon with reference to IPC-2221.   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.

Victor,
