The demand to implement more functionality on limited amount of space promotes miniaturization. This makes hybrid joints under various conditions and also in the micro range necessary. Existing solutions often have restrictions due to the principle of joining. A plastic forming process based on laser induced shockwaves is used to realize sheet‐sheet connections. The knowledge of joining of metallic sheets by laser‐induced shock waves should be used to enable the joining of aluminum with dissimilar materials such as glass and plastics. For industrial applications the dimensioning is important in matters of strength and feasibility of a joint. Therefore an upper bond estimation for the joining strength is developed. The design of the joint can be described on the basis of material properties. Moreover, the stiffness of the joining partners can be used as the decisive criterion for the joining possibility in the joining area. The advantages of this process are applied to different material combinations.
