Method of manufacturing adhesive joints between surfaces, having good mechanical strength

摘要

A mechanically-strong, adhesive bond is made between surfaces (10, 20), which conducts electricity and heat well. At least an area (101, 201) of the surfaces with slight roughness is prepared for adhesive bonding. The surfaces have a small peak-to-valley roughness (less than 0.3 mu m) (t) and are set opposite, leaving an intermediate space (30) in which a low-viscosity, setting adhesive (3, special epoxy) is applied, spreading over an area to a small mean thickness (d). The adhesive in the interspace is then hardened, maintaining the separation (d). The adhesively-filled interspace is less than 0.3 mu m thick (d) on average. An at least 20 x 20 mu m<2> area of interspace is used. The connection so made is also claimed.
