Physical Testing: Shear Testing/Pull Testing

Shear/Pull Testing

With our process, the lead can be gripped and subjected to a pull test to assess the strength of the solder joint. With in-house cross-sectioning and visual and SEM imaging capabilities, the resultant fracture can be analyzed (i.e. ductile or brittle fracture, IMC thickness, etc.). 

Foresite utilizes a Dage 4000 Bondtester in its shear and pull testing. The Dage 4000 Bondtester is capable of 100 kg of force in the Y-axis (shear) and 10 kg of force in the Z-axis (pull). Foresite has a variety of test cartridges available including 100 g and 5 kg tweezer pull, 10 kg hook pull, and 5 kg and 100 kg shear.

The Nordson DAGE 4000 conforms to, and in many cases exceeds, the following industry standards:
