Abstract: A method for forming an external electrode of an electronic component, which can apply sufficient conductive paste to even an end, and is able to enhance reliability as an electronic component. In the method for forming an external electrode of an electronic component, a conductive paste is applied to a printing target through a metal mask composed of a hole and a mesh portion disposed to surround the outer perimeter of the hole. The metal mask has the outer perimeter of the hole located inside a printing region of the printing target, and the outer perimeter of the mesh portion is located outside the printing region of the printing target.

Abstract: An electroacoustic transducer includes an ultrasonic element that includes a diaphragm and a support frame, a case body that accommodates the ultrasonic element, and fixing portions that join the support frame portion to a bottom plate portion of the case body. First and second main surfaces of the diaphragm face top and bottom plate portions of the case body, respectively, and a sound hole is provided in the case body. The fixing portions are partially provided along the circumferential direction of the support frame such that a space between the second main surface and the bottom plate portion communicates with a space around the ultrasonic element, and an acoustic path connecting the first main surface and the second main surface and the sound hole is provided in the case body. The fixing portions are defined by a die bonding agent including spherical spacers.

Abstract: A method of manufacturing an electronic component module includes sealing a surface of an aggregate substrate on which a plurality of electronic components are mounted with a sealing resin and cutting boundary portions between electronic component modules from an outer surface of the sealing resin to a position at least partially through the aggregate substrate to form first grooves. A shield layer is formed by coating the outer surface of the sealing resin with a conductive resin and filling the first grooves with the conductive resin, and recesses are formed at positions on the shield layer where the first grooves are formed. The boundary portions between electronic component modules are cut along the corresponding recesses so that second grooves each having a width smaller than the width of a corresponding one of the recesses are formed, and the aggregate substrate is singulated into the individual electronic component modules.
