    • An electronic device and an electronic component mounting method are provided to increase standoff effectively by connecting a solder particle to a dummy pad installed on one of a lower surface of an electronic component and a surface of a printed wiring board. An electronic device includes electronic components(60,70) and a printed wiring board(50). The electronic components have pads(601,602,701) on lower surfaces(61,71). The printed wiring board has pads(502,503,504), which are bonded to the pads of the electronic components, on a surface(51) and is electrically connected to the electronic components. A dummy pad(501,702) is installed on one of the lower surface of the electronic component and the surface of the printed wiring board. A solder particle(403,405) is bonded to the dummy pad to collide against the other surface of the electronic component or the printed wiring board.
    • 提供电子装置和电子部件安装方法,通过将焊料颗粒连接到安装在电子部件的下表面和印刷电路板的表面之一上的虚拟焊盘来有效地增加间隙。 电子设备包括电子部件(60,70)和印刷电路板(50)。 电子部件在下表面(61,71)上具有垫(601,602,701)。 印刷电路板在表面(51)上具有与电子部件的焊盘接合的电极(502,503,504),并与电子部件电连接。 在电子部件的下表面和印刷电路板的表面之一上安装虚拟焊盘(501,702)。 焊料颗粒(403,405)结合到虚拟焊盘以与电子部件或印刷电路板的另一个表面碰撞。
