Description
本出願は、2019年5月2日の出願日を有する米国仮特許出願第62/841,917号の出願利益を主張するものであり、参照によりその全体が本明細書に組み込まれている。
本主題は、概ね、表面実装薄膜構成要素、詳細には、コンプライアント端子を備える表面実装薄膜ヒューズに関する。
表面実装は、回路板組立体に好ましい技法となっている。その結果、事実上すべての種類の電子構成要素が、表面実装(すなわち、リードなし)の実施形態または用途向けに再設計されたか、または再設計されている。表面実装デバイス(SMD:surface mount device)をすべての種類の電子回路に迅速に組み込むことが、SMDヒューズについて対応するニーズを生み出した。
本開示の一実施形態によれば、表面実装可能な薄膜ヒューズ構成要素は、上面と、第1の端部と、第1の端部から長手方向に離間された第2の端部とを有する基板を備えることができる。薄膜構成要素は、基板の上面の上に形成されるヒューズ層を備えることができる。ヒューズ層は、薄膜ヒューズトラックを備えることができる。外部端子は、基板の第1の端部に沿って配置され、薄膜ヒューズトラックと電気的に接続され得る。外部端子は、導電性高分子組成物を含むコンプライアント層を備えることができる。
当業者には、本開示が例示的実施形態の説明にすぎず、また本主題のより広義の態様を制限することは意図されておらず、より広義の態様が、例示的な構造で具現化されていることを理解されたい。
