摘要:
One of an electrode terminal of an electronic component and a connecting terminal of a wiring substrate is provided with solder beforehand, one of the wiring substrate and the electronic component is secured, and the electrode terminal and the connecting terminal are made to abut each other so that one of the wiring substrate and the electronic component, whichever is not secured, is held. The electronic component is heated so that the solder melts, and the solder is solidified while the electronic component is held, so that the electrode terminal and the connecting terminal are bonded to each other by the solder. Further, while an interval formed between the wiring substrate and the electronic component by the melted solder is being held, the electrode terminal and the connecting terminal are finely moved relative to each other with reference to a surface of the wiring substrate in an XYθ direction.

[Problem] To improve productivity and reliability in mounting an electronic component.[Means for Solving Problems] At least one of an electrode terminal of an electronic component and a connecting terminal of a wiring substrate is provided with solder beforehand, one of the wiring substrate and the electronic component is secured, and the electrode terminal of the electronic component and the connecting terminal of the wiring substrate are made to abut each other in a state where one of the wiring substrate and the electronic component, whichever is not secured, is held. Then, the electronic component is heated so that the solder is melted, and the solder is solidified while the electronic component is held, so that the electrode terminal and the connecting terminal are bonded to each other by means of the solder. Further, while an interval formed between the wiring substrate and the electronic component by the melted solder is being held, the electrode terminal and the connecting terminal are finely moved relative to each other with reference to a surface of the wiring substrate in an XYθ direction.

A prepreg for a printed wiring board includes fluorocarbon fibers as a reinforcing material, and the reinforcing material is impregnated with a resin. The fluorocarbon fibers include short fibers having a branch structure. The reinforcing material includes a nonwoven fabric formed by interlacing the fluorocarbon fibers in the thickness direction. The proportion of the fluorocarbon fibers among the fibers constituting the nonwoven fabric ranges from 50 wt % to 100 wt %, and the remaining fibers are synthetic fibers or inorganic fibers. The nonwoven fabric is heat-treated at 330° C. to 390° C., then annealed at 200° C. to 270° C., and impregnated with the resin. This prepreg can used to provide a printed wiring board with low Interstitial Via Hole connection resistance and high connection stability and a method for manufacturing the printed wiring board.
