Gold electroplated spectacle frames

Electromigration of Electroplated Gold Interconnects

Electromigration tests were performed on passivated electroplated Au four terminal Kelvin line structures using the conventional in situ resistance monitoring technique. The stress conditions were a current density of 2.0 MA/cm with ambient temperatures ranging from 325°C to 375°C. The temperature coefficients of resistance (TCR) values were measured prior to current stressing to calculate the ...

Obstruction of vehicle-drivers' vision by spectacle frames.

Materials and allergens within spectacle frames: a review.

The materials that have been reported as causing allergic contact dermatitis within spectacle frames are identified, and their most likely location on the frame is highlighted. The lack of any real control over spectacle frame quality and content is indicated to be a problem, as is the difficulty in determining the true source of many frames. Much of the information must be obtained from anonym...

Nanopipette-Based Electroplated Nanoelectrodes.

Here, we report a nanopipette-based electrochemical approach to prepare metal nanoelectrodes with excellent control over electrode size, shape, and thickness of the insulation wall. Nanoelectrodes are prepared by electrochemical plating in a laser-pulled quartz nanopipette tip immersed in a liquid gallium/indium alloy electrode, which not only protects the ultrasmall quartz tip but also starts ...

Electrochemical Effects in Electroplated

Hybrid microcircuit packages are multicomponent electronics devices used in high tech military equipment. They also find application in medical devices for implant in humans to abort the attack of many life threatening illnesses. These are electroplated with limited thicknesses of nickel (1.25 8.75pm) and gold (1.25 5.6pm). In addition there are post plate baking and steam aging requirements as...
