This abstract is a brief summary of the referenced standard. Tarnish Resistance To increase the tarnish resistance of the silver plating, supplementary coatings such as a painting or powder coating can be recommended depending on subsequent finishing steps and solderability.
This specification establishes asfm requirements for electrodeposited silver coatings that may be mat, bright, or semibright, and are usually employed as solderable surfaces and for their electrical contact characteristics, high electrical and thermal conductivity, thermocompression bonding, wear resistance on load-bearing surfaces, and spectral reflectivity.
All our processes are certified to ISO Ast, supplementary tarnish-resistant treatment. Coatings shall be sampled, tested, and conform accordingly to specified requirements as to nature, purity, appearance, defects, adhesion, solderability, hardness, spectral reflectance, aatm conductivity, hydrogen qstm relief, and thickness measured either nondestructively by beta backscatter, X-ray spectrometry, or magnetic method, or destructively by coulometric technique or microscopical cross-sectioning procedure.
Historical Version s – view previous versions of standard. This standard does not purport to address the safety concerns, if any, associated with its use.
The adhesions of the silver plating can be adversely affected due to a weak copper and silver inter-metallic layer. Some of these applications include: As it is not a rare, naturally occurring metal, silver oxidizes quickly but out of all the metals, its the one that is the most electrically and thermally conductive.
It also offers excellent corrosion resistance and solderability. Our extensive quality control measures throughout production include non-destructive testing in accordance with ASTM to measure the thickness of the coating. Silver plating is a highly electric conductive and has outstanding properties for contacts and connectors.
Corrosion Protection A nickel undercoat with silver plating can b70 used for applications where corrosion protection is important.
Some of these applications include:. Go to Navigation Go to Content.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. When a nickel undercoat is not used on copper and copper alloy materials or when a copper undercoat is used on other materials, then the silver plating service should not be used for continuous service at a temperature in excess of degrees Fahrenheit. Coatings shall be classified into types according to minimum purity, grade according to surface appearance bright, semibright, or matand class according to whether any surface treatment has been applied.
Our state-of-the-art equipment allows us to meet tolerances of 25 micro inches. It also offers protection form fretting erosion and has strong corrosion resistance.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Nonmagnetic Coatings on Magnetic Basis Metals. Silver plating is best used for applications in electronics and engineering where good solderable surfaces and good corrosion resistance are required; for high electrical and thermal conductivity in electrical contacts, for thermo-compression bonding, sound reproduction applications, electrical applications that require spectral reflectivity, and other types of electronic applications.
