Rokah, There are no open standards for this test. Also, Werner Engelmaier and others will tell you that shear/pull testing has no place in reliability testing. However, it certainly can tell you if you are going to have any infants (cold joints, Black Pad, insufficients). The British NPL also has some interesting data that suggests that pull/shear testing and long term reliability are not completely divorced from each other, but a lot more work needs to be done. regards, Bev Christian Research in Motion -----Original Message----- From: Reuven ROKAH [mailto:[log in to unmask]] Sent: July 17, 2003 9:50 AM To: [log in to unmask] Subject: [TN] Pull test for SMT components Hi Technetters, Pls inform if you know any std. or research on solder joints pull test for SMT components per shape type (0805, 1206, gull wing, plcc using force gauge (table with minimal force for each component). I think it should be per area (mm square ) of the connection between the PCB to the component termination. e.g. I am not askeing about HASS od HALT tests.
