Abstract:
A method of fabricating a surface acoustic wave device, comprising the steps of:(a) disposing a first surface of a surface acoustic wave element facing an opposed portion of a first surface of a printed circuit board, the first surface of the surface acoustic wave element including at least a transducer portion; (b) disposing a member comprising hot melt material so that peripheral portions of said member extend beyond an outer perimeter of said surface acoustic wave element over a portion of the first surface of the printed circuit board distinct from and surrounding said outer perimeter of said surface acoustic wave element; and (c) sealing a space portion formed between said opposed portion and the first surface of the surface acoustic wave element by heating and deforming at least said peripheral portions of said member so as to form a sealing contact with at least part of the portion of the first surface of the printed circuit board distinct from and surrounding said opposed portion without the member spreading into the space portion, further comprising the step of disposing a frame-shaped member on the first surface of the printed circuit board in such a way that the frame-shaped member surrounds the space portion prior to performing step (a).
