Abstract
Description
本発明は、アジン系着色剤を含有する絶縁塗料、及び、この絶縁塗料を塗布した電子部品、更に、この絶縁塗料を用いた電子部品の製造方法に関する。 The present invention relates to an insulating paint containing an azine-based colorant, an electronic component coated with the insulating paint, and a method for manufacturing an electronic component using the insulating paint.
電気機器は、年々小型軽量化及び多機能化の傾向にあり、これを制御する各種電気機器に搭載した実装回路板は、湿気、塵埃、ガス等から保護する目的で絶縁処理が行われる。この絶縁処理方法としては、アクリル系樹脂、シリコーン系樹脂等の塗料を塗布する保護コーティング処理が広く採用されている。そして、このような実装回路板は、過酷な環境下、特に高湿度下で使用されることがあり、例えば洗濯機、自動車、フラットパネルディスプレイ等の機器に搭載されて使用されている。
しかしながら、背景技術にて述べたアクリル系樹脂の塗料は、耐熱性が８０〜１００℃という低温であり、加熱劣化後には可撓性が失われ、耐熱性が要求される電子部品での使用ができず、その用途が限定される。一方、シリコーン系樹脂の塗料は、耐熱性に優れ、加熱劣化後の可とう性が良いものの、材料価格が高く、塗料に皮張り、ゲル化等が発生し作業性に問題があった。 However, the acrylic resin paint described in the background art has a heat resistance of a low temperature of 80 to 100 ° C. and loses flexibility after heat deterioration, so that it can be used in an electronic component that requires heat resistance. It is not possible and its application is limited. On the other hand, the silicone resin paint has excellent heat resistance and good flexibility after heat deterioration, but the material price is high, and the paint has a problem of workability due to skinning and gelation.
また、実装回路板に絶縁塗料を塗布した場合、実装回路板に搭載される電子部品の部品番号等が印字隠ぺいされない問題があるが、特許文献１に開示されるアゾ系着色剤を用いることにより、隠蔽問題を解決することが出来た。但し、近年では、環境問題によりアゾ化合物の使用が問題視されている。 In addition, when insulating paint is applied to the mounting circuit board, there is a problem that the part number of the electronic component mounted on the mounting circuit board is not concealed by printing, but by using the azo colorant disclosed in Patent Document 1 We were able to solve the concealment problem. However, in recent years, the use of azo compounds has been regarded as a problem due to environmental problems.
本発明は、耐熱性を有し、作業性が良好で、アゾ系着色剤を用いることなく印字隠蔽を行える絶縁塗料、またこの絶縁塗料を用いた電子部品、更に、この絶縁塗料を用いた電子部品の製造方法を提供することを目的とする。 The present invention is an insulating paint having heat resistance, good workability, and capable of concealing printing without using an azo colorant, an electronic component using the insulating paint, and an electronic device using the insulating paint. It aims at providing the manufacturing method of components.
