本发明系关于一种以保持固定间隔之方式接合电子零件时所使用之电子零件用接着剂,且本发明之目的在于提供一种可高精度地保持接合电子零件间之距离,而获得高可靠性之电气设备,并且可使用喷射点胶设备连续稳定地进行涂布之电子零件用接着剂。本发明系用以接合电子零件之电子零件用接着剂,其含间隔粒子、环氧化合物(A)及硬化剂,该间隔粒子之CV値为10%以下,该环氧化合物(A)具有重复单位中含有芳香环之10聚物以下之分子结构,于25℃为结晶性固体,且于50-80℃之温度之以E型黏度计测量时之黏度为1 Pa.s以下。

This invention provides an adhesive for electronic components for use in bonding of electronic components while maintaining equal intervals of the electronic components. The adhesive for electronic components can highly accurately maintain the distance between the bonded electronic components, can provide highly reliable electric apparatuses and further can conduct coating using a jet dispense apparatus in a continuous and stable manner. The adhesive for electronic components is an adhesive for bonding electronic components and comprises spacer particles having a CV value of not more than 10%, an epoxy compound (A) which has a molecular structure having 10 or less monomer units and containing an aromatic ring in each repeating unit, is in a crystalline solid form at 25 DEG C and has a viscosity of not more than 1 Pa s as measured with a E-type viscometer at a temperature of 50 to 80 DEG C, and a curing agent.
