Modern electronic equipment often requires EMI Gaskets to avoid radiating EMI/RFI and to prevent susceptibility to outside sources of EMI/RFI. EMI Gaskets designed and manufactured utilizing the strengths of beryllium copper (BeCu) are the industry standard throughout the world. Starting with the emergence of RFI problems in the early days of military electronics, BeCu EMI Gaskets have been the choice solution.

BeCu EMI Gaskets do two things very well:

1. Their mechanical spring characteristics far surpass all other gaskets in the industry.
2. They offer the highest EMI shielding effectiveness.

CGC has been designing and manufacturing BeCu EMI Gaskets since the early days of the computer and electronics industries. WE combine these years of manufacturing and EMI experience with one key ingredient -- the needs of the customer.

Our innovative EMI Gasket designs are a direct result of out experience and customer input. Our new CompactPCI line of EMI Gaskets is an example of a design that was driven by the needs of a customer and evolved into a line of gaskets that meet all the requirements for CompactPCI faceplate standards while providing superior mechanical and shielding performance.

CGC offers many standard off-the-shelf EMI Gaskets as well as the engineering and custom manufacturing experience to help you solve your application. Whether you need one prototype or a large quantity order, our Team at CGCis available to respond to your needs.

Today's computer and telecommunications circuit cards demand increased EMI performance; EMC professionals find the old triangle profile's (solid top gasket) performance is marginal at best and degrades significantly over time. Thus the need for a high performance, post heat-treated, post-plated beryllium copper (BeCu) gasket that exhibits improved performance and withstands thousands of insertion cycles without degradation.

Leader Tech works closely with industry leaders designing new gaskets to meet the emerging needs of today's micro sized and multi-gigahertz electronic equipment. The new 7-19PCI gasket was jointly developed with a leading telecommunications company to improve the EMI seal between Compact PCI circuit card faceplates. This was accomplished by using a series of individual finger contacts rather than a continuous strip contact that flexed poorly and suffered deformation over time. This improved design also reduced the force load buildup and allowed for easy card insertion in racks of 20+ circuit cards.

Drawing on our EMI gasket experience, we selected these design features:

• A series of individual fingers to achieve maximum conformal contact.
• A single radius dome top profile to ease card loading and eliminate high stress in the contact area of the spring.
• The industry standard manufacturing process for BeCu fingerstock gaskets (post heat-treated and post-plated alloy 25).

Because of our extensive research and positive feedback from leading EMC professionals, we at Leader Tech think this is the best PCI gasket available in the industry. We offer two BeCu gasket sizes for extrusion variations and, for cost driven applications, we also offer both sizes in stainless steel.
