Tests prove copper gasket performance
Laird Technologies has verified the results of computer-simulated testing on its Recyclable Clean Copper gasket products using custom-designed test equipment.
Faster access to beryllium-free EMI shielding
Fingerstock standard products made from recyclable clean copper are now available within two business days.
Currently, Recyclable Clean Copper alloys cost about 10% less than copper beryllium (CuBe) alloys.
Additionally, Recyclable Clean Copper contains 13% less copper by volume and is therefore less affected by increasing variations in copper prices than similar products that contain CuBe.
Moreover, the Recyclable Clean Copper gaskets meld strong stability with tensile strength to achieve high levels of thermal and electrical conductivity and elasticity making it suitable for utilisation in both grounding and shielding applications at a rate that is comparable to traditional metal EMI shields.
Additionally, shielding performance is similar to other copper alloys with values over 100dB shielding effectiveness readily achieved.
"The Recyclable Clean Copper shielding gaskets extend our continuing commitment to protecting the environment in which we live and work", said Peter Graustein, Global Product Director for Metals Products, Laird Technologies.
"This alternative material also exhibits better stress relaxation properties than many other solutions, allowing it to maintain pressure longer at contact points resulting in higher end product quality and longer system life spans for automotive, computer, military and telecommunications devices".
Recyclable Clean Copper is fully compliant with EU RoHS Directive 2002/95/EC and alleviates the environmental, safety and segregation concerns associated with the traditional use and recycling of beryllium-based copper alloys.
This gasket material is characterised by superior yield strength (up to 100MPa) compared with other common copper alloys.
Key applications for this product include navigation and infotainment systems, NAS or SAN storage systems, high-end servers and communications display units, as well as basestations, handsets and network enclosures.
The flameproof product is targeted at high-volume designs, and custom stampings are available on request.
