A method and assembly that makes use of an adhesive to form a joint structure between two members, such as two heat transfer components. A first member has a slot in a surface thereof, while the second member has an edge received in the slot of the first member. One or both of the first and second members has one or more features that force the edge of the second member away from the first surface of the slot and into contact with the second surface of the slot during insertion of the edge into the slot. An adhesive within the slot bonds the second member to the first member.
