Solder ball shear strength
Websamples was tested by measuring the shear strength of the joints. The ball-shear tests were carried out using a 4000 series Dage Bond Tester. The shear speed and shear height kept at 0.7 mm/sec and 0.1 mm respectively for all the solder balls. For any particular ageing period the test sample size was 15, that is, 15 solder balls http://www.aecouncil.com/Documents/AEC_Q100-010A.pdf#:~:text=Solder%20ball%20shear%20strength%20shall%20be%203200%20gram%2Fmm2,modes%20are%20defined%20in%20Table%201.%20Separation%20modes
