摘要:
In a wiring substrate, formation of voids due to underfill filling failure is suppressed. A wiring substrate includes an insulating base layer, an insulating layer laminated on the base layer, and an electrically conductive connection terminal projecting from the insulating layer inside an opening. The insulating layer has a first surface with an opening, and a second surface located within the opening and being concave toward the base layer in relation to the first surface. The second surface extends from the first surface to the connection terminal inside the opening. On a cut surface which is a flat surface extending along a lamination direction in which the insulating layer is laminated on the base layer, an angle which is larger than 0° but smaller than 90° is formed between a normal line extending from an arbitrary point on the second surface toward the outside of the insulating layer and a parallel line extending from the arbitrary point toward the connection terminal in parallel to the first surface.
摘要(中):
在布线基板中,由于底部填充失败而形成的空隙被抑制。 布线基板包括基底绝缘层,层压在基底层上的绝缘层以及在开口内从绝缘层突出的导电连接端子。 绝缘层具有带开口的第一表面以及位于开口内并且相对于第一表面朝向基底层凹入的第二表面。 第二表面从开口内的第一表面延伸到连接端子。 在作为沿层叠方向延伸的平坦表面的切割表面上,在基底层上层压绝缘层时,在从任意点延伸的法线之间形成大于0°但小于90°的角度 在所述第二表面上朝向所述绝缘层的外侧以及平行于所述第一表面的从所述任意点朝向所述连接端子延伸的平行线。
