In the deposition potential range from -0.45 V to -0.60 V, the obtained deposits are the mixtures of Sn and CuSn alloys, indicating that the phase structure of these deposits is independent of the deposition potential.
Herein, we utilized the direct template-free electrodeposition method to synthesize CuSn from 1-ethyl-3-methylimidazolium dicyanamide ([Emim][DCA]).
To further develop the model of independent NP services and gain wider acceptance among academic health centers, CUSN decided to open another service, the Center for Advanced Practice Nurse Associates (CAPNA) located in the Upper East Side.
The contacts are bronze (CuSn) or brass (CuZn), depending on the cable type.
CUSN already offers shared branching, mobile banking and deposit and CO-OP Member Center services through the big California CUSO.
The intermetallic connection of Agsn and CuSn possesses much higher melting temperatures than the alloy themselves.
They are the $14 million Cornerstone CU of Des Moines, Iowa; the $157 million Fitzsimons CU of Lakewood, Colo.; the $297 million State Employees CU of Santa Fe, N.M., and the $30 million Westminster FCU of Westminster, Colo., CUSN said.
Too much copper in the solder might also promote the formation of CuSn crystals.
The service will allow 24-hour membership applications on the front end while providing credit reporting, ID verification, automated decisions and cross selling of loans and cards from the back end, CUSN said.
In the case of the bare copper PCB pad, the copper would be available to dissolve into the molten solder during reflow and form CuSn intermetallics.
CUSN allows credit union members to access their accounts at over 3,800 locations nationwide.
Using FE-STEM and FE-TEM microstructural observations for vertical sections of each Cu leadframe with the coating, cross-sectional morphologies of CuSn intermetallic compound (IMC) formed at the interface between the coating and leadframe were found to be wedge-shaped for the Sn/Cu-CUFE sample and in the shape of the teeth of a comb for the Sn/Cu-CUCR sample.
