摘要: 电子部件安装构造体包含基板;形成于基板表面上的、以Cu等高熔点金属为主体的导电性配线图案;将导电性配线图案的端子接合位置内包、搭载于所述基板表面的搭载位置上、具有外部端子的电子部件。外部端子在端子接合位置处以埋入到导电性配线图案的内部的状态与导电性配线图案相连接。因此,与仅在导电性配线图案的表面上将电子部件的外部端子与导电性配线图案连接的接合部相比,可以在强度更高的接合部处将外部端子与导电性配线图案连接。

摘要: 在将由分散剂(102)涂布表面的金属纳米粒子(101)混合到有机溶剂(105)中前或混合后,将氧作为氧纳米气泡(125)或氧气泡(121)注入有机溶剂(105)中,通过加压烧结制造用于接合半导体芯片的电极和线路板的电极以及/或半导体芯片的电极和另一半导体芯片的电极的金属纳米油墨(100)。将该金属纳米油墨(100)的微液滴射出到电极上,在半导体芯片的的电极和线路板的电极上形成凸块,使得半导体芯片反转,对位叠合在线路板上后,对各电极间的凸块加压并加热,加压烧结凸块的金属纳米粒子。由此,抑制加压烧结时产生空隙。
