Zusammenfassung: | PROBLEM TO BE SOLVED: To fill the gap between the underside of an electronic component and one surface of a substrate appropriately with a mold resin, in a configuration where upper and lower sides of the electronic component mounted on a substrate are sealed with the mold resin.SOLUTION: A mold package includes a substrate 10, an electronic component 20 having an element 21 separated from one surface 11 of the substrate 10 and a component electrode 22 integrated with the element 21 and connected with one surface 11 of the substrate 10, and a mold resin 30 for sealing one surface 11 of the substrate 10 along with the electronic component 20. The mold resin 30 fills the gap between the lower surface 21a of the element 21 and one surface 11 of the substrate 10, and covers the upper surface 21b of the element 21. Around the electronic component 20, a frame 14 projecting above one surface 11 of the substrate 10 is provided, and the side face of the frame 14 on the electronic component 20 side is an inclined plane 14a approaching the electronic component 20 from above one surface 11 of the substrate 10 toward the one surface 11.
【課題】基板上に搭載された電子部品の上下の両側がモールド樹脂で封止されている構成において、電子部品の下側と基板の一面との間にモールド樹脂が適切に充填されるようにする。【解決手段】基板10と、基板10の一面11とは離間した素子部21と素子部21に一体化され基板10の一面11に接続された部品電極22とを有する電子部品20と、電子部品20とともに基板10の一面11を封止するモールド樹脂30と、を備え、モールド樹脂30は、素子部21の下面21aと基板10の一面11との間に充填されるとともに、素子部21の上面21bを被覆しており、電子部品20の周囲には、基板10の一面11上に突出する枠部14が設けられ、枠部14における電子部品20側の側面が、基板10の一面11の上方から当該一面11に向かって電子部品20に近づくように傾斜した傾斜面14aとされている。【選択図】図1 |
