Manufacturing methods and boundary acoustic wave device of the boundary acoustic wave device

摘要

The part which is connected with outside electrically has been reinforced the external terminal and the external terminal of the elastic boundary wave element securely, furthermore production method of the elastic boundary wave device which invasion such as humidity from the boundary between 1st and 2nd medium of the elastic boundary wave element is difficult to occur is offered. At least, in order one beer hole electrode 20a and 20b one side from the principal plane on the other hand to penetrate to the principal plane, in order one side of the hardenable resin seat which is provided on the principal plane, for external terminal 16of a elastic boundary wave element 10, 16b and beer hole electrode 20a and 20b to be connected electrically, it arranges elastic boundary wave element 10, in order next, to cover the part which has appeared in external surface of boundary between 1st and 2nd medium 11,12 of elastic boundary wave element 10 at least with the hardenable resin seat, it pushes in elastic boundary wave element 10 into the hardenable resin seat, hardening the hardenable resin seatDoing, it makes resin seat hardening ones 18, each process is had, production method of the elastic boundary wave device.
