SOLDERING METHOD BETWEEN WAVEGUIDE AND FLANGE

摘要

PURPOSE:To avoid generation of pinholes by champering the peripheral part of a hole at the coupled surface side of a flange. CONSTITUTION:A rectangular hole 11 for insertion of a waveguide 2 made of an aluminum material is formed to a flange 1 also made of an aluminum material. Then the peripheral part 13 of the hole 11 is champered over the entire circumference at the side of a coupled surface 12. The champer size (c) is set larger than the cut processing size (t). The waveguide 2 is put into the hole 11 of the flange 1 so that the tip of the waveguide 2 protrudes slightly over the surface 12. Under such conditions, both the flange 1 and the waveguide 2 are heated and the flux is coated to a champered surface 13. Then a solder material is welded to the part 13 for soldering, and the surface 12 is cut flat after the soldering.
