Gaskets and cushion pads are often provided with pressure sensitive adhesives to facilitate the assembly process.  There are multiple forms of adhesives including acrylic, rubber based, and silicone based pressure sensitive adhesives applied to specific gaskets and cushion pads.  Acrylic sensitive adhesives form the majority of adhesives supplied on gaskets and can withstand temperature changes within the range of -40 degrees F to 250 degrees F.  Silicone based adhesives tend to be more expensive, usually have a shorter shelf life, and have lower adhesive levels on most substrates.  They do however remain useful in the temperature ranges of –80 degrees F to 400 degrees F.  Because NEDC Fabricating Solutions has on premise water jet cutting capability we are able to select and coordinate specific prototype gaskets utilizing conductive compounds to meet your entire adhesive and EMI shielding needs.   Come visit us at www.nedc.com or call us at 1-800-224-6332 with any and all questions.  We will be happy to solve your entire gasket shielding needs!     

EMI/RFI shielding is an important concept with regards to both the electronic engineer and the enclosure designer.  At NEDC Fabricating Solutions we recognize both aspects of the process. The electronic engineer must always consider EMC when thinking about the layout and the circuit design when attempting to limit or eliminate the majority of EMC emissions.  Often the design for which the electronic engineer puts forth may not be sufficient to attenuate emissions to the required levels and shielding of the enclosure may be necessary.  Of primary importance to the designer is the specific thought to the placement of screening gaskets at joint surfaces.  Enclosures may be made from any material provided that it is conductive.  Metallic enclosures intrinsically have this characteristic.  Plastic enclosures, which are in widespread use, need to also be conductive which can be obtained using conductive paint, electroplating, or vacuum metallization.  More often than not these enclosures are not just a simple screened box and may have openings for such purposes as optical design, ventilation, and cable entries.  Surface-mount gaskets, gaskets in grooves, flange/gasket conduction, as well as corrosion all have to enter the thought process in the design of these enclosures.  Because we here at NEDC have had many years of die cutting and EMI shielding experience we feel we can assist you in all your specific design application needs.  Call us at 1-800-224-6332 with any need you may have.  We can also be seen at www.nedc.com 
 

There has been a marked increase in the use of microwave electronics in the military sector within the last several decades.  Because of this trend there has also been a paralleled increase in potential RF interference.  The release of RF interference can and often results in among other things wrong targeting, lowered operating efficiency, and limiting operating capabilities.  With the use of microwave absorbing materials such issues can be eliminated or sharply reduced to allow more improved system performance.  Microwave absorbers (RAM) are materials specifically designed to attenuate or absorb microwave energy.  RAM’s are designed to convert absorbed energy to heat.  Because there has been an increase in the use of military electronics, most notably microwave electronics with resultant increases in RF interference, microwave absorbing materials are continually being upgraded, developed, and re-designed to meet the increasing demands of not only the military but the commercial sector as well.  At NEDC Fabricating Solutions we continue to strive to keep pace with all the advances in microwave absorbers and shielding capabilities.  Our engineers will help you with all your specific materials and design needs.  Call us at 1-800-224-6332.  A list of our products and materials as well as our services can be seen at www.nedc.com  

At NEDC Fabricating Solutions we recognize the diverse choices with regard to EMI shielding.  When dealing with products such as automotive or medical electronics, telecommunication equipment, avionics, or general computers it is important to choose the most effective EMI shielding gaskets.  Three choices or options include conductive foam over fabric, conductive elastomers, or beryllium-copper strips (finger stock).  To distinguish between the three, one needs to decide the detail of the forms, environmental protection, and the differing EMI protection. 
Fabric over foam is generally the choice when the productive profile is not too intricate, mechanical durability is of low demand, and there is no need for an environmental seal.  Elastomers provide a broad spectrum of attenuation capabilities as well as being efficient in relation to environmental and moisture sealing.  One would opt for BeCu strips when there is a strong need for mechanical durability primarily in relation to frequent direct compression and shearing forces.  Whatever your material or design needs may be, NEDC’s twenty five years of experience in the die cutting industry as well as the expertise of our engineers will welcome the opportunity of helping you through all your EMI shielding needs.  Call us at 1-800-224-6332 or see us at www.nedc.com     

In respect to EMI/RFI seals around shafting or grounding capabilities, O-ring or cylindrical gaskets made from knitted wire mesh are ideal.  At NEDC Fabricating Solutions our materials range from shielding wire mesh strips, wire mesh over elastomer core, compressed mesh gaskets, cable wire mesh, etc..  Our engineers recognize key factors in determining proper material selection including but not limited to temperature range, compression forces, standard specs, and conductivity or thermal performance.  Call us at 1-800-224-6332 so we can assist you with all your fabricating needs.  We can also be seen at www.nedc.com

The importance of EMI/RFI shielding cannot be understated.  The most common type of EMI occurs in the RF range of the EM spectrum from 10 to the 4th to 10 to the 12th hertz.  The energy comes from many sources including but not limited to computer circuits, overhead power lines, lightning, and electric motors.  Because of the ever growing electronic compound industry and its electromagnetic energy outputs, device failures are becoming commonplace.  As a result the design and production of housings and containers have become specific and of outmost importance in limiting small openings that allow penetration of EM pollution. At NEDC Fabricating Solutions our Engineers recognize the importance of Materials selection and proper design to ensure the highest device success rate possible.  To learn more of our service visit us at www.NEDC.com or contact us at 1-800-224-6332.

The primary purpose of EMI shielding is to reflect, absorb, or redirect electromagnetic waves to prevent interference from affecting sensitive equipment.  EMI can originate from a variety of sources including outside signals from other equipment or from the affected component itself.  EMI shielding, whether it is in computers, medical devices, cell phones, televisions, or even windows play an integral part in preventing as much interference as possible.  There are many forms of EMI shielding including sheet metal, conductive paint, and electro less plating.  EMI/RFI shielding gaskets are the most effective and cost effective method of shielding.  The primary reason for gasket selection is its ability to prevent slot antennas.  At NEDC Fabricating Solutions we pride ourselves on the successful design, fabrication, and effective distribution of high quality EMI/RFI gasket shielding products.  We use a variety of EMI/RFI Materials that will best suit your specific needs.  We can be reached at 1-800-224-6332 or visit us at www.NEDC.com   

In the last several years there has been a sharp increase in the use of conductive fabric over foam gaskets for EMI shielding.  For various reasons including plating adhesive improvements, profile design, and availability of flame retardent material the use of fabric over foam has become a primary choice for EMI shielding in respect to indoor electronic housing applications.  Because there has been such a sharp spike in the commercial electronic sector the need for cost effective materials paralleled with successful applications has resulted in the growth of fabric over foam utilization.  The ease of application has also been a reason for the switch from metal spring fingers such as beryllium copper to the more popular foam over fabric.  One concern is that fabric over foam is not the best choice for applications where temperatures approach 70 degrees and above, and when long-term performance is critical.  Regardless of your need, New England Die Cutting Fabricating Solutions will work with you to fit your materials and design specifications.  Call us at 1-800-224-6332 or you can see us at www.nedc.com
