fingerstock
Ultrasoft® Series
UltraSoft® fingers have been designed for communications, computers and electronic systems designers concerned with EMI compliance and lightweight enclosure designs. Available in the same full range of standard configurations, UltraSoft fingers offer designers greater flexibility and versatility than ever before —permitting more extensive use of lighter, thinner construction materials to help cut costs and/or enhance system performance.
The unique advantages of UltraSoft (98-Series) fingers include:
• The lowest compression forces in the industry
• Increased life cycle
• Shielding effectiveness comparable to similarly configured standard 97-Series parts
• Wide selection of sizes and configurations
• Low compression force version available for virtually every standard shielding product
UltraSoft (98-Series) products are available in the same lengths as the standard (97-Series) products. Please refer to the appropriate standard product pages for specific information. All UltraSoft products are also available in your choice of finishes.

Recyclable Clean Copper™
Recyclable Clean Copper products meld strong stability and tensile strength with high levels of thermal and electrical conductivity making it suitable for utilization in both grounding and shielding applications at a cost that is comparable with traditional metal EMI shields. Shielding effectiveness is similar to other copper alloys with values over 100 dB shielding effectiveness readily achieved.
Recyclable Clean Copper is fully compliant to EU 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 alternative material exhibits excellent corrosion resistance, platability, solderability and stress relaxation properties. It is characterized by superior yield strength (around 1000 MPa), and excellent elastic resilience compared to other common copper alloys.
The product is targeted at high volume designs. Custom stampings are available upon customer request. As with all of Laird Technologies metal fingerstock gaskets, Recyclable Clean Copper is completely flameproof. This preliminary catalog presents some typical RCC products. For mounting methods and other specific product information, please see Laird Technologies catalog "Fingerstock, Gaskets and Metal Grounding Products".
Recyclable Clean Copper (RCC) beryllium-free EMI shielding offers customers an excellent alternative to beryllium containing alloys (BeCu) in a wide range of slotted applications. The conversion of part number (Stock Item) of BeCu to RCC:
