MOLDING METHOD OF SAW FILTER

摘要

PURPOSE: A molding method of a saw filter is provided to carry out a molding work of a saw filter by an adhesive when sealing a saw filter by the insert molding. CONSTITUTION: A lower plate(130) is formed by an insert molding manner and has a stepped portion(150) formed at a limb together with a lead wire(120) of a saw filter(110). A coupling protrusion is formed by the insert molding manner together with an upper plate(140) placed at an upper side of the lower plate. An insulating adhesive(170) is coated on an inner side wall comprising a stepped portion formed on an upper limb of the lower plate and a surface coupled with the upper plate. A side and a lower part of the upper plate are fixed to an adhesive-coated surface. After adhering the upper and lower plates, a resultant structure is heated in a heating furnace so as to harden the adhesive.
