<p><P>PROBLEM TO BE SOLVED: To provide a relay member and a printed board unit having favorable electric performance than before. <P>SOLUTION: A chip-type electronic component 27 is combined to a base material 25. The base material 25 is sandwiched between a package substrate 17 and a printed wiring board 14. A first electrode terminal 31 of the electronic component 27 is connected to a first terminal pad 21 of the package substrate 17. A second electrode terminal 32 of the electronic component 27 is connected to a second terminal pad 22 of the printed wiring board 14. Thus, the electronic component 27 is electrically connected to the package substrate 17 and the printed wiring board 14. A distance from the electronic component 27 to the package substrate 17 is drastically shortened as compared with the case that the electronic component 27 is mounted to the surface of the printed wiring board 14 outside a contour of the package substrate 17. As a result, a loss R and an inductance L are drastically reduced. Favorable electrical performance is established than before in a printed board unit 13. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
