One key application for the manufacturing of MLB and HDI printed circuit boards are pretreatment systems aimed at providing the optimum adhesion of organic coatings such as Photoimagable Resists (such as Dry Films [DF] and Liquid Photo Imageable Resists [LPIR]) or Solder Mask's (SM). The most common way for this optimum adhesion to be achieved is to use an etching solution to roughen the copper surface...
Hydrophobic titanium oxide (TiO2) film formed on metallic titanium substrate in hydrogen peroxide solution with a subsequent oxidation under air atmosphere. Component, microstructure, and hydrophobicity of the oxide film were characterized by X‐ray diffraction, scanning electron microscope, and water contact angle methods. Corrosion resistance tests were carried out in seawater solution at different...
Purpose: The purpose of paper is to determinate thermal stability and mechanical properties of sputtered chromium-molybdenum-nitride (CrMoN) coatings. Design/methodology/approach: We have deposited 1.8 m-thick ternary Cr0.5Mo0.5N1.0 films on a CoCrMo alloy using a RF dual magnetron sputtering system, with Cr and Mo targets and N2 as the reactive gas. These films were subjected to various thermal treatments...
