Outline | 503_1012_tin plating strategy.pdf Once a plating process has been approved, the same plating process may be used at other locations within Tyco Electronics and at our suppliers. The plating process is documented, including the chemistry of the plating process and all process control parameters. These specifications are shared (under confidentiality agreement) with our suppliers. Each plating plant that provides lead free tin plating to Tyco must adhere to these practices. For initial installations, the plant must provide a sample of plated product to Tyco Electronics for inspection and analysis. X-ray diffraction is used to characterize the crystallographic morphology of the plating and compare the orientation to known good samples on file. Known good samples are those samples that have already successfully passed the JEDEC tin whisker test. Since the crystal orientation can change is the process parameters are not followed, this test provides assurance that the process is operating according to specification. Audits of the plating plants further ensure compliance to the specification. Conclusions |
