	Check out IPC-TM-650, Method 2.4.8.  It lists the required angle, 
rate, and measurement method to use.  All of which have an influence over the 
results.  Also, Section 5.8.3 has a test pattern that you can use.
	To get the peel started, I always used an Exacto-Knife to lift the 
copper foil off the laminate.  Be extremely careful though.  My other hand was 
always wearing the thickest leather glove I could get by with for fear of 
sharp blade slicing my hand.
