Metallization of alumina ceramics by electroless-plating.
Circuit Technology, 1989 アルミナ基板と無電解めっき皮膜の密着機構を解明するため、触媒活性化にSnCl2とPdCl2, Pdアルカリイオン, Pdコロイド, Cuコロイドを用いて, 密着強度の検討を行った。その結果, 触媒活性化は密着強度にほとんど影響を与えず, 無電解CuとNi-P皮膜の密着強度は, 基板の表面粗度が0.24μmのとき, それぞれ1.5kgmm-2, 2.5kgmm-2であった。これらの皮膜の密着強度は, それぞれの皮膜の初期析出形態に影響をうけることがわかった。触媒活性化の種類にかかわらず, 無電解Cuめっきの初期析出形態は粗く, 粒子状の析出物となるが, 無電解Ni-Pめっきは均一で緻密な皮膜が析出した。それにより, 基板と皮膜の界面におけるCu皮膜強度はNi-P皮膜のそれに劣っており ...

Flexural Vibrations of Bilaminar Ceramic Plates [PDF]
The Journal of the Acoustical Society of America, 1964 The differential equation and boundary conditions that govern the electrically forced flexural vibrations bilaminar ceramic plates are developed from linear piezoelectric equations of state. A general formula for the electrical-input admittance of a bilaminar plate is given. The differential equation can be cast in the classical form for thin plates by

Gold plating metallized alumina ceramics
, 1978 Problems with gold plating a metallized ceramic part at the General Electric Neutron Devices Department led to a two-fold study. The first part of the study evaluated the production process and resulted in a temporary solution to the problems. The second in-depth part of the study evaluated methods for surface activation, the plating process and ...

Electroless Copper Plating on PZT Ceramics.
The Journal of Japan Institute for Interconnecting and Packaging Electronic Circuits, 1995 PZTセラミックスは, 圧電性を有するので, 圧力センサやレゾネータ, コンデンサなどの電子部品に利用されている。従来, PZTセラミックス上の電極や回路形成には, 導電性ペーストが利用されてきた。しかし, 電子部品の小型化に伴う微細回路の形成には, 導電性ペーストの適用が困難となってきた。それゆえ, PZTセラミックス上への無電解銅めっきの成膜について検討を行った。通常, セラミックスと無電解銅めっき間の密着性を得るためには, セラミックス表面を酸でエッチングする必要がある。しかし, PZTセラミックスの場合, エッチングを行うと本来持っている電気的特性が著しく低下するため, エッチングレスで無電解銅めっきを成膜する手法が求められている。そこで ...
