At HZB, research is being conducted into how the supply of synchrotron light from BESSY II can be improved to enable new experimental techniques and detectors at the beamlines. There, permanent magnets are playing an increasingly important role in the construction of new multibend achromat-based particle accelerators to deflect charged particles. Another central part of this research is the development of modern permanent magnet undulators. One of the challenging areas with these is the precise assembly and placement of permanent magnets. Due to increased requirements, such as reducing the period length of an undulator, new concepts for mounting the magnets have become necessary. Properties such as fatigue strength, shear strength and in certain contexts, e.g. with in-vacuum undulators, the vacuum resistance of the connection must be investigated. For this purpose, methods have been developed to investigate the load capacity of adhesive and solder joints. The presentation shows how these are applied and what the consequences are for the application.
