发明名称 METHOD OF ASSEMBLING CLOSED-TYPE ELECTRONIC COMPONENT AND ENCLOSED SAW FILTER
摘要 PROBLEM TO BE SOLVED: To provide a method of assembling a closed-type electronic component which is capable of stabilizing a product quality and reducing a packaging cost, and also to provide an enclosed SAW filter. SOLUTION: A recessed part 118 is formed in a member 111a for enclosing an active section, and then the member for enclosing an active section and a SAW filter 122 are bonded to each other, enclosing a comb-like electrode section 123 of the SAW filter in the recessed part. Therefore, when assembling the enclosed SAW filter, there is no damage to be given to the comb-like electrode section 123. Since the member for enclosing an active section which is used is a flat-type one, there is no need of a package having a special shape which has been used in the conventional case, and a process of providing a cover is not necessary. Compared with the conventional case, therefore, the product quality can be increased and the packaging cost can be reduced. COPYRIGHT: (C)2003,JPO
