Description
効果をもたらし、ドーム状板の特定の形状は噴射特性に影響する。
refinement in the solidification of undercooled Ni−Pd alloys”.Journal of Crystal Growth 309(2007)103−111、Sept 14 2007の内容全体が参照により組み込まれる。一般に、パラジウムおよびニッケルを含む大部分の電気めっき溶液が有効であり、或いはニッケルのみ、または実際にはリンおよびニッケル(14:86)または白金も有効である。耐食性を与えるために、非パラジウムウェーハに、PdNiにおいて表面でめっき(0.5〜5.0μm厚、好ましくは1.0〜3.0μm厚)することができる。これはまた、小さい開口が望ましい場合には、孔サイズを小さくする。
、市場で受け入れられるには大きな経済的障壁となる。
(i)単位面積当たりの孔の数を大きくすることができる、
(ii)より小さく、直径方向により正確な孔サイズが可能である、
(iii)市販されている既存のウェーハと同様の厚さであり、既存の制御装置の正確な振動数に適合してエアロゾル発生器を作動させるために、ネブライザを再設計するという面倒な必要を軽減する、
(iv)2つのめっき層またはめっきステップしか必要でない、
(v)ウェーハをマンドレル基板から慎重に剥がすことが依然として容易である、
(vi)既存の電子制御装置を使用して、固有振動数が適合するときに開口板を駆動することができ、同様の開口板厚さが達成された、
(vii)より小さく、より制御可能な粒径(2〜4μm)を得ることができる、
(viii)より大きい流量(0.5〜2.5ml/分、より一般的には0.75〜1.5ml/分)を達成することができる、
(ix)記載した先行技術と比較して、互いにより独立した流量および粒径を達成することができる(一般的に、先行技術では、流量の増加が、通常、粒径の増加を必要とし、また逆も同様である)。これらの利点を図10のプロット図に示す。
もよいことが想定される。例えば、より高い耐食性および/またはある親水性もしくは疎水性のために、一方または両方の表面の組成が異なっていてもよい。また、上部の1〜5μmまたは1〜3μmの表面層について、さらなるめっきステップがあってもよい。
Claims (10)
