• Tips for specifying electroless-nickel coatings
  assemblies such as landinggear components, ramp-locking systems, and flap and actuator components from corrosion and wear. Electroless-nickel (EN) plating is also known as chemical or autocatalytic nickel plating. In contrast to the electroplating (galvanic) technique, EN plating baths work without...
• MICRO:Building Copperopolis, by Bruce Maeda, p.39 (Sept '99)
  undergone extensive qualification testing to verify system effectiveness and reliability. After initial start-up and commissioning, the system was placed in continuous service to process spent plating baths and wafer rinsewater from process-development and wafer-processing runs. The system demonstrated...
• MICRO: The Hot Button
  areas of concern are copper electroplating and CMP. Can ultraclean plating baths capable of producing uniform, low-impurity, void-free films be developed that will help keep copper resistivity in check? How will on-line chemical metrology and the analysis of copper electroplating evolve and improve...
• Thermal spray: Better performance for less
  in the laboratory. Early testing standards were generally set for components to meet or exceed 22 hr. Current standards call for up to 66 hr of exposure. But new plating processes now let components exceed 100 hr of testing before deterioration is apparent. Some OEMs are pushing for a standard of 200 hr...
• Zing Electroplating
  iron or low carbon stampings. 2) Toxicity, waste-treatability, etc. G. 3) Direct bath operating cost including waste treatment, not pre or post plating costs or equipment costs. 4) Bath's ability to tolerate or compensate for poor preparation. I. Z. I. N. D. O. *Sodium and potassium baths...
• Automation comes to wet-processing stations
  wet-processing stations for etching, cleaning, stripping, and plating. The controllers are Model 2700 units from Control Technology Corp., Hopkinton, Mass. They coordinate the transfer of items from one bath to another via a servo-driven X-Z robot arm. State language capabilities built...
• Zinc Blackening
  , it is for all practical purposes (not specification though) zinc plating. When it comes to corrosion resistance, results show up to five times (we like to use three times) the salt spray resistance. There is more good news however! The chromate used in this process does not contain silver...
• Durmalon: An Alternative to Cadmium (.pdf)
  , Columbus (DSCC) added three Cadmium alternative finishes. to MIL-DTL-38999, Rev L (and other connector specs): Nickel-PTFE (Polytetrafluoroethylene). Pure Dense Electro-Deposited Aluminum (Alumiplate). Zinc-Nickel. Amphenol's Durmalon. The Olive-Drab Cadmium plating (Class W) over aluminum shells...
• MICRO:Building Copperopolis (Jan '99)
  as well as electroless and electrolytic plating each with different grain sizes and fill characteristics. There are still many important issues to be resolved, however, before dual-damascene copper technology can be successfully implemented. Tantalum (Ta)- and tungsten (W)-based diffusion barriers...
• MICRO: TechEmergent
  . Although the sensor in this study was used to gather data from surface-preparation processes, it has been developed for all liquid-chemical process areas. It can be used for blending CMP slurry at the point of use; monitoring ECD plating baths, solvents in ultrapure water, chemical drain lines...
