Green plating system to oust cadmium
The TTHT plating system greatly eases the task of providing effective and durable corrosion protection for brass and aluminium components, while adhering to environmental requirements.
Icore International's new TTHT plating system greatly eases the task of design engineers who must provide effective and durable corrosion protection for brass and aluminium components, such as connector backshells, while adhering to environmental requirements, like those resulting from the European Waste Electrical and Electronic Equipment Directive A key feature of the innovative TTH system is that it entirely eliminates the use of cadmium, a material which is well known to be toxic and carcinogenic

The design of high-current electrical connectors can be made much easier by using the strip-form Band 8 and Band 12 sprung contact elements from interconnect specialist Icore International
For these reasons, many countries, both within and outside Europe, are currently enacting legislation which will ban or severely penalise the use of cadmium, making the need for alternative forms of corrosion protection particularly urgent.
TTH plating from Icore International fully satisfies this need.
It is based on the use of a proprietary nickel-PTFE process, which deposits a continuous, impervious and hard-wearing protective coating.
Tests have shown that, even in the most demanding military, marine and aerospace applications, this coating provides corrosion protection which is greatly superior to that which can be achieved using traditional cadmium-based methods.
In conventional salt-spray (fog) tests, the corrosion resistance of TTH plating is more than 2kh, compared with the 500h typically achieved by conventional cadmium-over-nickel plating.
In addition, TTH-plated aluminium components regularly resist the effects of the demanding US Navy sulphur fog salt spray tests for more than the qualifying acceptance period of 200h, with almost no visible corrosion.
The real-life performance of TTH-plated components is even more impressive, with typical products outlasting their cadmium-nickel plated equivalents by a factor of 12 or more.
Further benefits of Icore International's new TTH plating include superior abrasion and impact resistance, which mean that the plating resists damage even in adverse operating conditions.
Its electrical conductivity is at least as good as conventional cadmium-nickel plating and, with an operating temperature range of -65 to +260C, TTH plating is eminently suitable for use on components which will be used in cyclic-temperature applications.
