IPC 4552A ENIG specification finally released.
August 22 2017.
Finally after many years of testing, evaluation and negotiations between the committee members the long awaited rev A of the ENIG specification IPC 4552 has been released. This is a major rewrite with very specific process and measurement capability requirements that were not in the original specification. Additionally and what may be the most significant portion of the document is the inclusion of a nickel hyper corrosion chart which details three levels of hyper corrosion and determines acceptability, rejectability or further testing required to determine outcome.
S T and S Group can assist in all aspects with meeting the requirements of this new specification from testing finished product to evaluating compliance of suppliers to the process and measurement capability requirements specific for the ENIG plating process.
