Abstract
【解決手段】発光素子用印刷回路基板は、第1金属層111と、前記第1金属層の一面に形成される第2金属層112と前記第1金属層の他面に形成される第3金属層113とを含む基板と、前記第2金属層上に形成される絶縁層120と、前記絶縁層上に形成される回路パターン130と、を含み、前記絶縁層には、発光素子パッケージを収容するためのキャビティー160が形成され、前記第1金属層の熱伝導度は、前記第2金属層及び前記第3金属層の熱伝導度より高い。
【選択図】図1
Description
本出願で、「含む」または「有する」などの用語は、明細書上に記載された特徴、数字、段階、動作、構成要素、部品またはこれらを組み合わせたものが存在することを指定しようとするものであって、1つまたはそれ以上の他の特徴や数字、段階、動作、構成要素、部品またはこれらを組み合わせたものの存在または付加可能性をあらかじめ排除しないものと理解しなければならない。
第3金属層113は、基板110表面の酸化防止機能を行うことができる。
アルミニウム素材は、銅素材に比べて相対的に軽量であるが、高い熱抵抗を有する。したがって、基板110において第2及び第3金属層112、113の厚さの比率が低いほど熱抵抗が減少する。一方、基板110において第2及び第3金属層112、113の厚さの比率が高いほど軽量の基板製造が可能であり、基板価格が減少する効果がある。
絶縁層120は、基板110と回路パターン130が電気的に連結されることを防止する機能を行う。
絶縁層120は、多様な方法で第2金属層112上に結合され得る。
回路パターン130は、伝導性を有する金属を利用して形成される。例えば、回路パターン130は、銅または銅を主成分とする銅合金で形成され得る。
