Description
1)本発明の技術的な利点は、底部電極のみを保留し、ナノ絶縁材料を採用して製品本体を覆う金属磁性粉末コアからなる一体式チップインダクタを提供することである。これにより、スラリー末端封鎖からなる電気めっき型、材料片スポット溶接からなる電極型の一体式チップインダクタ製品のサイドのスズ積層サイズを節約し、回路基板上における製品の設置サイズを縮小し、集積回路PCBボードの設置スペースを増やし、集積回路産業の高度の集積化開発に有利な条件を作り出す。同じサイズの場合、製品の総合的な性能が大幅に向上できる。
2)製造過程でイオンプレーティング技術又は従来の電気めっき技術を使用し、めっき層の緊密性を向上しながらめっき層を4層から2層に減らし、製造コストを節約し、工程収率を向上する。
3)新しいナノ絶縁コーティング材料及びナノ絶縁コーティング工程を使用し、製品の絶縁コーティングの厚さを5μm以上にする。絶縁コーティング材料は、環境にやさしい熱硬化型のポリエステルイミド系の材料である。
