MOUNTING STRUCTURE OF SURFACE-MOUNTED DEVICE, AND LOADING STRUCTURE BODY AND REINFORCED LOADING METHOD OF SURFACE-LOADING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a loading structure body of a surface-loading device for sufficiently mitigating stress applied on an external junction terminal of a surface-loading device caused by dropping impact of a mobile terminal such as a mobile phone.;SOLUTION: The loading structure body 1 of the surface-loading device is constituted with a printed circuit board 2, a BGA package 3 as the surface-loading device loaded to the printed circuit board 2, a reinforcing member 4 covering the BGA package 3 loaded to the printed circuit board 2 bridging over the BGA package 3, and a clamping pin 9 as a clamping member placed in contact on the upper surface of the BGA package 3 through a ceiling plate 4a of the reinforcing member 4 and fixed to the reinforcing member 4 with solder 8.;COPYRIGHT: (C)2009,JPO&INPIT
