This contamination can have the effect of producing discoloration of the deposit. This abstract is a brief summary of the referenced standard. When plated parts are used in mating applications, the maximum thickness shall not exceed the tolerance speci? Oxidation of co-deposited metals can make soldering more difficult.

Gold Plating – ASTM B, AMS , MIL-G | Accurate Precision Plating

The thickness of the underplating should be consistent with end-use requirements see 6. Initial scanning should be carried out for all elements in order to detect any unknown or unexpected metallic impurities. However, care must be taken to ensure that the thickness of the Type I or Type II gold topcoat is sufficient so as not to compromise wear properties.

See Guide B for guidelines for selecting the appropriate test method. 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.

A suggested four-point method is detailed in Test Method F We offer our clients a superior product due to our attention to detail wstm commitment to quality, supported by the highest level of customer service. To convert mass of gold per unit area that is present over the measured area to a geometrical thickness, it is necessary to use standards having a density identical to that of the coatings to be measured, or to multiply the reading obtained by factor, f.

For that reason, the electrodeposition of gold is used extensively in electrical component applications such as electrical contacts, connector pins, switches, sensors and many others for which repeated physical contact occurs.
