Plating of Aluminum for Solderability Zinc Immersion Pre-Treatment Process
|Publication Date:||1 November 2017|
This specification covers the requirements for preparation of aluminum and aluminum alloys for soldering by zinc immersion pre-treatment followed by copper plating and tin or tin-zinc alloy plating.
This process has been used typically to facilitate soldering of aluminum and aluminum alloy mechanical and electronic instrument enclosures, but usage is not limited to such applications.
The final plating shall be one of the following. When a Class is not specified, Class 1 shall apply.
Class 1 - Tin Plating
Class 2 - Tin-Zinc Plating
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
