With total thickness of 22 microns, SF-PC5000 film is formulated for flex interconnects, COF, hinge applications in cellular phones, and LCD drivers. Tatsuta System Electronics Co., Ltd released a new EMI shield film, SF-PC5000, formulated for flex interconnects, COF, hinge applications in cellular phones, digital camera modules and LCD drivers. Shielding is a fast way to comply with legal requirements like CE or FCC or to prevent electro-magnetic interference. Corrosion protection is very important for applications near to the sea (due to salt) and in outdoor applications. We have designed special resilient gaskets, such as Ultra Soft Shield and V-shape gaskets.
To give you an idea of what kind of gasket would be suitable for your application, you can send a drawing (preferably including dimensions, quantity needed, materials of the enclosure and indication of stiffness of enclosure material) to our specialists.
We can produce our gaskets in any desired quantity, whether it is just one gasket or a thousand, and all gasket can be made to your specifications.
The conductive layer on the outside of the gasket needs to be in the same galvanic range as the construction materials, otherwise galvanic corrosion will occur and the electrical conduction within the structure will be lost. Aluminium housings:When you need to EMI-shield an aluminium housing, we recommend using 6800 series Amucor shielding gaskets.
To obtain a contact surface within the same galvanic range as the conductive covering of the gaskets, a Conductive Tape with a conductive self-adhesive on the back can be applied. Another way to avoid galvanic corrosion is to prevent corrosive environmental influences from reaching the EMI shielding gasket, for example by the means of a gasket that combines a water seal with EMI shielding (fig.
Some manufacturers of EMI shielding gaskets use layers containing carbon on the outside of the gasket to prevent corrosion.
For high frequencies (HF shielding > 40 MHz), only a very thin layer of highly conductive material would suffice. The allowed stiffness of the gasket depends on the rigidity of the construction and the distance between the fixings. For shielding doors and lids, it is important that you use a gasket with the correct resiliency. For conductive metal Faraday cage doors, a 8700 series V-shape gasket or 2000 series Be-Cu Fingerstrips is most frequently used. For applications where a relatively small and watertight gasket is required, we can deliver 5750 electrically conductive rubber o-profiles. Not only connections between construction parts, but also displays and vent panels need to be shielded. The shielding of the displays will have to be connected with the shielding of the enclosure to guarantee optimal attenuation. To prevent radiation from escaping the shielding through power and signal cables, they need to be shielded or filtered. The shielding of the cables always needs to be properly connected to the shielding of the enclosure; otherwise the shielding will have a lower (possibly insufficient) attenuation level. Please note that cables without a shielding jacket need to be shielded outside the shielded enclosure as well to prevent them from acting like antennas. Shielding PCBs and shielding individual components can also be achieved by soldering vertically placed metal strips (e.g. If the radiation source or the EMI sensitive component is known, shielding for the specific component(s) can be applied. For some applications, it is desirable to shield an entire room by attaching metal foils, such as Mu-copper foil, to the walls.
The same as the 1500 series Clip -on PCB shielding cans, but with teeth in order to glue the can onto the PCB.
Here you can download datasheets of 1500 to 1800 - series EMI shielding solutions for PCB's.
United Western Enterprises is experienced in developing, manufacturing and improving custom RFI and EMI shielding.

One piece shielding, shielding with peel away tops or two piece shields consisting of a a€?fence and covera€? combination are typical designs for shielding.
The disturbance of EMI (electromagnetic interference) may cause consumer electronic devices such as notebook and digital cameras unable to function normally. Gore offers a variety of EMI shielding components with unique features and reliable performance for mobile electronics such as smartphones, tablets, notebooks, and telematics. GORE® EMI Shielding Materials offer unique features and reliable performance for demanding applications. The Surface-Mount Technology (SMT) Series of GORE® EMI Shielding Materials combines unsurpassed conductivity with the convenience of SMT- compatible format. GORE® SNAPSHOT® EMI Shields are revolutionary, multi-cavity, board-level EMI shielding products for wireless communication devices. With a total thickness of only 22 microns it is especially well suited for dynamic flex operations and acts as a covercoat in addition to its shield properties.
The film exhibits excellent thermal stability during reflow with no blistering, warp age and minimal shrinkage. The use of electronical devices increases as well as the exposure to a wide range of frequencies. Our shielding solutions are cost-effective, since time-consuming development is not required to meet EMI demands. At lower frequencies, such as 30 kHz and less, it is important to use materials with a good magnetical (and electrical as well when dealing with eddy currents) conductivity and possibly a thicker material will be needed as well. High frequencies, ranging between 100 MHz and 40 GHz, are very sensitive to small gaps in the enclosure. Our specialists are experienced with all sorts of shielding applications and take a look at over 50 designs on a daily basis.
To shield the vents (ventilation openings), we recommend using 9500 series Honeycomb ventilation panels. If the enclosure is to be painted, the tape can be provided with a masking tape of a slightly smaller width (the paint will cover the conductive tape along the edges, which increases bonding and corrosion resistance) (fig. Please be aware that these carbon layered gaskets are not galvanically compatible with many commonly used construction materials. If the gasket is too stiff, a door, lid or panel will deflect and gaps will be caused instead of prevented (fig.
Displays can be provided with a sputtered transparent conductive coating for HF shielding (>30 MHz, fig. Shielding can be provided by covering the cables with shielding tubes or by wrapping conductive materials around the cable.
For heavy duty and military applications, shielded cable glands and specially designed cable entry systems are available. Preventing such a leak in the EMI-shield can be done by installing a power- or signal line filter or, in case you are dealing with shorter cables leading to another shielded enclosure, using a wrap-shield or shielding tube.
9) made of Mu-copper shielding foil with an insulation layer on the inside or with plastic studs to avoid short-circuiting (fig. The best way of shielding at the source is to shield only the interfering part or the sensitive part on the PCB with our specially developed 1500 series PCB shielding system.
Think of medical and military applications and rooms to make very sensitive measurements in. The EMI shielding solutions for printed circuit boards are a compact solution for preventing electromagnetic interference on circuit boards. Gore offers a variety of material types and application forms, which range from highly customized precision die-cut solutions to standardized off-the-shelf solutions. These conformable materials are engineered to maintain consistent contact and low DC resistance. The technology consists of a lightweight, metalized plastic shield that is thermoformed to virtually any design, and an innovative attachment mechanism using solder spheres as individual mechanical snap features.
Therefore a wide range of cable diameters can be shielded with a single flexible shielding tube. Film exhibits thermal stability during reflow with no blistering or warpage, and minimal shrinkage. SF-PC5000 comes with a mat black finish while the original shield film SF- PC1000 is silver.
Radiation and immunity has to be taken into account in an early stage during the development of new products. Shielding is typically used in enclosures in order to isolate electrical devices inside from external influences and for cables in order to isolate wires from the environment through which the cable runs.

If shielding against frequencies around 50 Hz is required to limit influences from a transformer (that can cause health risks or influence the operating system of machines), then using dense metal layers and a special material called Mu-ferro should be considered (see magnetic shielding). The higher the frequency, the more attention should be paid to prevent holes and gaps in the shield. They are a cost-effective solution since no fundamental changes to the enclosure have to be made and there is no need for extra fasteners. They are specialized in picking the right type of gasket for any application and their advise is without charge. To prevent influences from lower frequencies, cables and enclosures have to be shielded with magnetically conductive materials.
In other words: doors, panels and other parts need to be connected electrically, on all sides (without gaps).
We have developed two different cable entry shields, one consisting of two fringed EMI gaskets on the top- and bottom side of a slot (4910 - Cable entry shield) and the other consisting of a contact plate (to be mounted in front of a slot) with holes for cable througput (4930 - High Performance cable entry shield). They consist of a 1mm thick die-cut material, which can be manufactured easily according to customer specifications, with little additional tooling costs (fig.
These compartments are closed by adding a lid of flexible die-cut shielding foil or by pressing a soft conductive foam sheet against the strips (fig. The technique may even be applied in forensic science, for example if a device needs to be blocked completely from communicating with the outside world while being examined.
To make it easy for you which IP rating you need for the desired result we have put all the IP rating in a clear table.
Shields can be etched as flat pieces with or without etched bend lines to ease forming at your facility or we can form at our in-house forming department. We have been constantly innovating and developing our EMI shielding cases to keep up with the market demand.
SF-PC5000 and 1000 comes with both a 50 micron PET transfer film for ease of handling and 120 micron film for protection.
In many cases EMI problems cannot be solved at PCB level alone and instead, the enclosures and cables will have to be shielded as well. If a quick market introduction is intended and the emission exceeds the set limits, easy-to-apply shieldings are a commonly used solution.
However, EMI shielding gaskets with a conductive layer of reinforced Amucor® foil are compatible with materials like zinc plated steel and aluminium.
Especially for doors, several kinds of gaskets have been developed which combine a very large compression range, a low closure force and high conductivity. A shielding tube consists of hollow braided metal wire, through which the cable or bundle of cables can be pulled in order to shield it. Part numbers, logos or other identification can be included on your shields as well, further developing the shielding to your requirements. We can provide you EMI shielding case for EMI solution and fast prototype sample to satisfy with your market demand.
Shieldings can be used for appliances with high radiation levels, sensitivity levels or for products of which these levels are not known in advance, like modular enclosures.
When the enclosure is used in a corrosive atmosphere, it is better to prevent contact with stainless steel, brass, or an aluminum chromate layer (alocrom 1200). The transparent conductive coating is delivered on foil (bendable and easy to stick onto a window), glass (standard window) or other materials (for heavy-duty purposes).
A wrapshield is a knitted metal wire tape, which is wrapped around a cable or bundle of cables. Though the plate system has a higher performance, the fringe system is easier for adding cables later on.
Shieldings are used when dealing with sensitive measurements that can be affected by ambient fields as well. The gasket selection diagram below could be very helpful in determining the appropriate gasket material. Honeycombs are usually supplied with a rigid aluminium frame and a gasket of 2-5 mm for optimal connection with the construction. It is easier to create branches with the wrapping method than it is to create branches with shielding tubes.
Shielding is evidently a wide-spread phenomenon and necessity in the electronics industry to meet today's emission standards.
