Hi Louis-
Can't be that hard, but results may not be as official. What about using some weights hung off a modified (soft jaw to grab the foil better) binder clip? Add a little weight, measure the stretch using calipers, and note both near breakage. Or spring for an Instron or Dage. IF it's for production, I'd think you could do a simple go/no-go test without too much trouble.

Subject: [TN] question for PCB fabricators
Technet PCB fabricators, I want to perform tensile strength and elongation testing on plated copper, TM-650, 2.4.18.1. At present, we are sending samples to an external lab once per month, but want data more often and more quickly, so are considering testing in-house.
Any fabricators performing this test in-house? How often?
Any suggestions from PCB users are also welcome.
