PROBLEM TO BE SOLVED: To provide a method of supporting an electronic component that can prevent an error operation because of a crack of soldered joint resulting from dynamic force, and to provide an electronic device for supporting an electronic component reliably. SOLUTION: The electronic device includes a printed circuit substrate 14 and a structure component 15 to cover at least a part of the PCB 14. The method includes a step to mount the electronic component 17 on the PCB 14, a step to supply an elastically compressible impact absorbable component 18 on the area 22 of the structure component 15, and a step to assemble the PCB 14 and structure component 15. The impact absorbing component 18 is composed to cover the electronic component 17. When assembling, the elastically compressible impact absorbing component 18 is located so as to affect an pressure onto the electronic component 17 on the PCB 14. The electronic device whose elastically-compressible impact absorbing component 18 is located between the structure component and PCB is disclosed. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To suppress the occurrence of conductive connection defects, caused by the reduction in the adhesive strength of insulating resin for making improved the electrical reliability of the mounting structure of a substrate and an electronic component bonded with insulating resin or an electro-optical device, including this mounting structure. SOLUTION: An electro-optical device 100 has a substrate 126, on which an electro-optical material is disposed, and an electronic component 130 is mounted on the substrate 126. A conductor, provided on the substrate and an electrode provided to the electronic component are conductively connected directly or indirectly, and the substrate and the electronic component are bonded by the insulating resin, and an inhibitor 140 which generates reaction, at least when the conductor and the electrode are separated is provided separate from the insulating resin.

PROBLEM TO BE SOLVED: To increase reliability by reducing the stress formed at a junction between a BGA device and a substrate. SOLUTION: A ball grid array device 322 is attached to a first side of a circuit board 320, and a reinforcing material 310 is secured to the circuit board 320 so as to surround the ball grid array device. Legs 332, 334, 336, 338 are formed in the reinforcing material and elements of the reinforcing material extending at each of legs, and bearing the strength for reinforcing the substrate are prepared so as to be separated from the ball grid array device mounting face on the substrate. Because the elements are separated, the rigidity against a bending moment which acts to the substrate and reinforcing material is increased, and the reliability is increased by reducing the stress formed at the junction between the ball grid array device and the substrate. Moreover, electronic parts can be mounted in the lower position of the element, and the mounting area on the substrate can be increased. COPYRIGHT: (C)2006,JPO&NCIPI
