Copper Beryllium Fingerstock
APPLICATION OF FINGERSTOCK GASKETS
EMI designers know and trust the consistent performance
of Fingerstock (CuBe) gaskets. To date, CuBe yields the
best electrical spring contact available in this industry. The
copper beryllium mills have well established techniques
and for decades have produced CuBe alloys per ASTM,
SAE, JIS, and DIN specifications.
Leader Tech uses only proven technology in creating
copper beryllium springs, contacts and gaskets. Beginning
with Alloy 25 (1/4 hard) BeCu, we stamp, form, and post
heat-treat to a hardness of 340 to 390 DPH. This process
is preferred in the EMI shielding industry because it has
proven to produce the best electrical spring contacts.
Leader Tech CuBe EMI shielding gaskets are the most
reliable in the industry.
Leader Tech manufactures a wide variety of standard
styles and sizes of CuBe gaskets. These gaskets operate in
spaces from .010 inches up to .410 inches. Using CuBe
materials as thin as .002 inch, we also offer many styles
as soft gaskets that provide the low compression force
needed in many applications. Leader Tech also designs
and manufactures custom spring contacts and gaskets.
Copper Beryllium – The Material of Choice
FINGERSTOCK 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.
Leader Tech has been designing and manufacturing
Fingerstock 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 Fingerstock Gasket designs are a direct
result of our experience and customer input. Our Compact
PCI 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 Compact PCI
faceplate standards while providing superior mechanical
and shielding performance.
Leader Tech offers many standard off-the-shelf
Fingerstock 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 Leader Tech is available to
respond to your needs.
