The investment in a new line for plating with noble metals, primarily gold, feels like the right decision for us with the movement towards electrification and the growing market, says Fredrik, laboratory manager.
A bigger demand for gold plating is the reason for Provexa Technology’s new line for surface treatment with noble metals. The big increase has mainly been in technical applications but also as a decorative surface treatment in some cases. Silver for highly technological applications will also be available in the new line.
Gold is more often used to get good solderability and ensure the electrical conductivity over time. Some examples of areas where gold is used are electronics, medical technology, biocompability, telecom and aerospace industry.
Provexa Technology will be able to offer both soft- and hard gold with several different pre-treatments and metals as a barrier layer. Soft gold, or pure gold, has a purity of 99,9%. Hard gold however is alloyed to achieve the right functions and abrasion resistance. It takes a large investment to be able to offer both methods, but the advantage is to always be able to offer the right method for the application of the product and its demands.
The most common reasons to use soft gold is solderability and corrosion resistance as well as being able to achieve consistent contact resistance over a wide temperature range.
A application for hard gold plating is at contacts areas where the contact force is high or where the demand for abrasion is high due to for example movement.
Provexa Technology will also be able to offer flash gold plating, duplex systems with both unalloyed and alloyed gold and EVABRITE® electrolytic anti-tarnish. We will also be able to apply a protecting layer of for example ceramics or polymer to increase abrasion resistance. Everything to ensure the right function and to be able to meet the demands for the products.

The dimension of the new line is 200 x 380 x 300 mm. The investment in a new line for plating with noble metals, primarily gold, feels like the right decision for us with the movement towards electrification and the growing market says Fredrik, laboratory manager at Provexa Technology. Daniel agrees and tells us that a large part of his work now consists of gold plating, since the demand has grown bigger lately and he admits that a bigger, more modern line will facilitate and increase efficiency of the production.
Gold plating performs well on several materials such as steel, stainless steel and aluminum as well as cupper and cupper alloys. Commonly used standards for gold plating are among others ISO 27874 and ASTM B488.
