Second part of 2020. A new customer in Covid Time. A new specific application: Custom IOT module testing machine. It was the first time we had the request of Surtec Chromital 650 applied on a partial surface. High conductivity and good surface protection for the Chromital side, coloured anodization to avoid corrosion on a second side of some components. Interesting isn't it? Challenging as well.
What is SurTec 650 Chromital? It is a passivation process based on non-toxic trivalent chromium, suitable for aluminium, aluminium alloys and magnesium.
This makes the surface highly conductive and it gives it a high corrosion protection. If you want to learn more or to contact them for support, follow the link to their website: Chrome(VI)-free Passivation for Aluminium (surtec.com)
Although SurTec 650 is a great solution, in process, problems were awaiting for us.
