<p><P>PROBLEM TO BE SOLVED: To provide a board usable with a large current, such as a DC-DC converter, and a method of manufacturing a board, which enable small electronic components to be arranged on the single board. <P>SOLUTION: A board 1 is a board having a transformer 3 and a choke coil 5 which can be used, for example, as an automotive DC-DC converter. The board 1 is so constructed that electronic components are mounted on an injection-molded substrate 2 in which internal circuit conductors are exposed out at electronic component mounting portions 7, a printed board mounting portion 11 and conductive portions 10a, and the other regions are coated in a resin 9. The printed board mounting portion 11 is a region where a printed board 15 is mounted. A conductive portion 10b of the printed board 15 is soldered or otherwise bonded to the conductive portion 10a of the printed board mounting portion 11 via an electronic component 17. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
