MOUNTING STRUCTURE FOR SURFACE MOUNTED DEVICE AND METHOD OF FIRMLY MOUNTING SURFACE MOUNTED DEVICE
First Claim
1. A mounting structure for a surface mounted device, comprising:
- a surface mounted device mounted on a printed circuit board;
a reinforcing member attached onto the printed circuit board and including a top plate covering at least a periphery of a top surface of the surface mounted device; and
a pressure member passing through the top plate of the reinforcing member, being in contact with the top surface of the surface mounted device, and being fixed onto the top plate with a fixing member.

Abstract
The present invention provides a mounting structure for a surface mounted device capable of reducing sufficiently the stress applied to external joint terminal portions of a surface mounted device due to an impact caused by, for example, dropping a mobile device such as a mobile phone. A mounting structure for a surface mounted device includes: a printed circuit board; a BGA package as a surface mounted device mounted on the printed circuit board; a reinforcing member attached to the printed circuit board astride the BGA package for covering the BGA package; and a pressure pin as a pressure member passing through a top plate of the reinforcing member, being in contact with the top surface of the BGA package, and being fixed to the reinforcing member with solder.

10. A method of firmly mounting a surface mounted device, comprising:
-
covering a surface mounted device mounted on a printed circuit board with a reinforcing member including a pressure member passing through a top plate of the reinforcing member and being soldered onto the top plate; and bringing the pressure member into contact with a top surface of the surface mounted device by melting the soldered portion using a heating reflow process to cause the pressure member to drop under its own weight.
