The pull-off test, also called stud pull test in which an adhesive connection is made between a stud and the carrier (or object to be tested) by using a glue, possibly an epoxy or polyester resin, that is stronger than the bond that needs to be tested. The force required to pull the stud from the surface, together with the carrier, is measured. Simple mechanical hand-operated loading equipment has been developed for this purpose. When higher accuracy is required, tests can be performed with more advanced equipment called a bond tester. A bond tester provides more control and possibly automation. Applying the glue automatically and curing with UV light is the next step in automation. This methodology can also be used to measure direct tensile strength or/and the bond strength between two different layers.

Apparatus and method for measuring bonding strength of multi-layer d2w hybrid bonded chip
This invention relates to an apparatus and method for measuring the bonding strength of multilayer D2W hybrid bonded chips, belonging to the field of semiconductor packaging technology. It addresses one of the problems of inaccurate and large errors in measuring the bonding strength of multilayer, small, and thin D2W hybrid bonded chips. The method of this invention uses the centripetal force generated during the chip's high-speed rotation to replace the tensile force applied during the pulling process. Since the centripetal force always acts perpendicularly towards the center of rotation, it is always uniformly applied to the bonding interface, avoiding stress concentration. The test is conducted under vacuum conditions, avoiding the influence of air resistance on the test structure's side surface on the uneven distribution of centripetal force under high-speed rotation. Extensive testing revealed that a correction factor α needs to be added to the calculation of bonding strength. This correction factor was obtained through comparison with currently widely accepted pull-out tests and is highly representative.

A device and method for indoor pull-out test of expansion-type anchor rod based on transparent rock mass
This invention relates to an indoor pull-out testing device and method for expansion anchor bolts based on transparent rock mass, belonging to the field of geotechnical engineering and tunnel support technology. The testing device includes a confining pressure loading system, a transparent chamber, an anchor bolt pull-out system, and a non-contact strain monitoring system. The transparent chamber is filled with transparent rock mass with a matching refractive index, and pre-drilled channels are installed within the rock mass to accommodate the expansion anchor bolts to be tested. During the pull-out process, an industrial camera captures real-time images of the full-domain deformation of the rock mass and anchor bolt through the transparent chamber, and the evolution data of the strain field at the anchoring interface is obtained by combining digital image correlation technology. This invention achieves visualized monitoring of the entire anchoring process of expansion anchor bolts, avoids mechanical interference from anchor bolt expansion on sensors, can simulate complex stress environments, and provides an experimental platform for the study of anchoring mechanisms.
