Many bond strength tests require a means to grip the part so that the strength of its bond can be tested. In many of these applications the geometry and force of the grip must be precisely controlled to ensure sufficient load can be applied to the bo

Could you please tell what are the current avaliable standards, if any (BSI/IPC) for a measurement value on the mechanical pull strength on SMT IC leads after reflow. Thanks in advance, Jack.

We have some no sticks, but that is actually a good thing because we have NSD. During process control audits we found that pull strengths to the board dropped off. We build a military application that requires higher bond strenghts. Low pull streg

YINCAE has developed a new innovative solder joint encapsulant paste. Designed to be used for mass production via dispensing or printing, SMT 256EP replaces traditional solder paste, flux, and underfill. SMT 256EP enhances solder joint strength by 5 to 10 times and has demonstrated high pull strength at both room and high temperatures (280°C).

The purpose of this study was to compare the strength of the bond between resin and glass cloth for various composites (laminates) and its dependence on utilized soldering pad surface finishes. Moreover, the impact of surface finish application on the thermomechanical properties of the composites was evaluated. Three different laminates with various thermal endurances were included in the study. Soldering pads were covered with OSP and HASL surface finishes. The strength of the cohesion of the resin upper layer was examined utilizing a newly established method designed for pulling tests.

Pad cratering is an important failure mode besides crack of solder joint as it’ll pass the regular test but have impact on the long term reliability of the product. A new pin pull test method with solder ball attached and positioning the test board at an angle of 30º is employed to study the strength of pad cratering. This new method clearly reveals the failure mechanism. And a proper way to interpret the finite element analysis (FEA) result is discussed. Impact of pad dimension, width and angle of copper trace on the strength is included. Some findings not included in previous research could help to guide the design for better performance
