A coating service to treat electrical components with the gold replacement material Silver MaxPhase™ is now offered by Swedish company Impact Coatings. The company, which has developed the material as well as the process, has set up its own processing line in-house with capacity to take on contract work.
A contract service for coating components with the gold replacement material Silver MaxPhase is now offered by by Impact Coatings, using PVD equipment for coating reel-to-reel as well as individual parts.
The metal alloy Silver MaxPhase is a newly developed material with similar properties to gold in terms of conductivity and corrosion resistance, but at a fraction of the cost. This can significantly reduce the production cost for connectors and other electrical components. The contract service is offered for individual parts as well as reel-to-reel on metal strip.
“Silver MaxPhase is very cost-effective in volume production, but setting up a production line for this process is quite a leap for many customers. By offering a contract service from our own premises, we now make the benefits of Silver MaxPhase available to users with smaller volumes and for pilot production runs,” says Henrik Ljungcrantz, the company’s CEO.
Silver MaxPhase is applied by physical vapor deposition (PVD), a process that takes place in a vacuum chamber where the material is evaporated and condensed to form a coating on the object.
Impact Coatings’ concept is an alternative to wet plating with gold. Over the past year the Silver MaxPhase coating has been qualified according to the IEC 60512 and IEC 60068 standards, for low voltage and low contact force connectors that are normally gold plated. Examples are battery and I/O connectors in consumer electronics.
The contract service is carried out at the company’s premises in Linköping in south-central Sweden, an area with good communications for transportation worldwide. Each new project is evaluated individually and its application and the requirements discussed with the customer.
