  • Design and fabrication of a miniaturized, integrated, high-frequency acoustical lens–transducer system
    To satisfy this relationship, chrome- gold - plated PZT-5A (Boston Piezo-Optics, Inc., Bellingham, MA) with a thickness of 100 µm was selected. … 5A crystal was evaluated for compliance to the design specifications using a roughness/step tester (RST, WYKO, Corp …
  • The effect of chemical polishing on the interface structure and electrical property of Au/Cd0.9 Zn0.1 Te contact
    … out after the preparation of Au electrodes by using an Agilent 4155-C tester in order to … Cross-sectional TEM specimens were prepared by bonding two parts of each sample together with a gold - plated surface face to face, fol- lowed by mechanical grinding along the direction perpen- dicular to the bonded interface to the thickness of 10 µm.
  • ZCP2003ISTFA125
    XRF testing was performed across the contact fingers of each board to determine if there was a correlation between gold thickness and the reported failures rates. limits/features of the XRF tester can minimize errors in plating measurements.
  • Adhesion of Electrolessly Deposited Nickel on Lead Zirconate Titanate Ceramic
    … grain-boundary etching was accomplished with a HBF, + HNO, acid mixture (percentages given represent volume percent of reagent grade in mixture), the sample was sensitized for elec- troless plating from a Sn2+solution … … was from aqueous PdC1,. Gold was deposited electrolytically over … Quantitative adhesion measurements on the metalized layer were performed using an adherence tester . ' Ni thicknesses were measured using X-ray fluorescence.
  • Investigation of ultrasonic Pd coated Cu wire wedge bonding on different surface finish
    This paper reports a study on the influence of surface finish type, deposition thickness and bonding machine … In this study, 0.7mil Pd coated Cu wire was bonded on three kinds of surface finish, as electro- plating Nickel and Gold , electro-plating Nickel, palladium & gold, Electroless Nickel, Electroless Palladium and Immersion Gold (ENEPIG). The noncontact optical profiler, microhardness tester and scanning electron microscope (SEM) were used to examine surface finish …
