In order to improve the shielding performance, increase product yield and reduce the thickness of shielded packages the use of conformal shielding with metal sputtering has been introduced. Tango’s proprietary segment carrier design maximizes the number of packages that can be placed on a single carrier. The cluster design of the Axcela HVM tool makes it possible for users to start with a single process chamber for low volume runs. Holland Shielding Systems BV had developed Fingerstrip gaskets and metal grounding products for shielding and grounding.
Beyond beryllium copper, we also offer shielding and custom-engineered stamping in stainless steel, brass, phospor bronze and other special alloys.
For applications where a small dynamic range is required and a clip-on mounting is preferred.
Mounting with self-adhesive tape, the beryllium copper shielding gaskets provide easy and secure mounting. Ideal for 90° applications where mounting to the surface perpendicular to the finger compression area is required. Circular fingerstrips are used for grounding and EMI shielding in high-frequency equipment and for forming large diamter round contacts rings.
The Fingerstrips are very easy to bend and are therefore suitable for round and very dynamic contacts.
Many of the Holland Shielding Systems BV gasket designs depend on the active contact surface (top) being engaged at, or behind, the cross-sectional centreline.
Application: for areas where both opposing surfaces can be connected by contacting at least one point of the shield gasket profile on each surface. Application: for areas where opposing surfaces can be connected by contacting one point of the shield gasket profile on one side and Conductive Tac on the other. Worldwide leading manufacturer of EMC (electromagnetic compatibility), EMI (electromagnetic interference) and RFI(radiofrequency interference) shielding solutions. Keep up to date with the latest developments in Holland Shielding Systems BV by signing up for our newsletter. Conductive adhesives and sealants are important part of emi noise reductions in cellular phones and other communication devices. Flexible conductive adhesive lamiantes used in shielding flexible printed circuit board are critical for the reduction of EMI noises in the smartphone applications. EMI shielding is the process used to protect sensitive electronic devices and components from various kinds of electromagnetic radiation.
Many different materials are used to provide EMI shielding and RFI shielding, and they can be applied in many different ways.
Magnetic Shield Corporation has been a worldwide manufacturer and distributor of custom magnetic shielding alloys and custom build shields since 1941. When electric fields exert forces on charges within these conducting materials, a current is generated within the shield.

Dexmet Corporation is dedicated to providing high quality products and is an ISO 9001:2008 certified company.
EMI enclosures are most commonly constructed from solid or perforated aluminum, stainless steel, nickel, or copper alloys. To support larger, interconnected systems, EMI gaskets can provide additional electromagnetic field, EMF, protection by preventing electromagnetic radiation from leaking in or out at gaps and seams between enclosures. In the past EMI shielding has been done with metal lids (“metal cans”) on packages or sprayed on epoxy shielding materials.
Adding process chambers to already installed Axcela systems can be done in less than one hour.
Also for use where high temperature or other design considerations preclude the use of adhesive-mounted gasketing. A positive contact force can usually be assured after the gaskets are compressed 25% of relaxed height and beyond.
We have one of the most experienced material engineering and application staff in the industry.
Electromagnetic radiation can interfere with the proper operation of electronic devices and other kinds of equipment. The electromagnetic shielding process uses almost exclusively metal materials since they provide the necessary conducting surface. We are best known for our MuMETAL® brand but also offer other alloys and products for various applications.
As a technological leader, we can provide EMI shielding to protect your sensitive electronic devices and components. Circuit boards and CPUs utilize many electronic components which generate electromagnetic fields.
EMI gaskets are generally made from a die-cut rubber material attached to a conductive metal material which serves as the EMI shield. With the introduction of high capacity carriers based on multi-process chamber cluster technology Tango has been able to offer the lowest CoO (Cost of Ownership) for any sputtered EMI shielding process.
At the same time the available active backside cooling allows for processing temperatures to be kept below 100 degrees C. No other EMI shielding equipment has the capability to offer modular expansion to quickly adapt to manufacturing volume changes. This electromagnetic interference, EMI, as well as radio frequency electromagnetic interference, RFI, can be limited using the electromagnetic shielding process.
For this reason, aluminum, copper, nickel, and steel alloys are all commonly used metals, however MuMetal®, an alloy of nickel, iron, copper, and molybdenum, is the industry standard for electromagnetic shielding. We are an ISO 2008:9001 certified supplier and our engineers are dedicated to providing customers with the high quality products they are looking for. Since 1982, we have been providing high quality, innovative solutions for customers all around the world, and we can do the same for you!

Similarly, magnetic fields induce eddy currents which cancel the applied magnetic field within the shield. We are a privately-held manufacturer of EMI shielding gaskets as well as o-rings, gaskets, adhesives, tapes, vents, and sponge and sealing products.
To limit electromagnetic interference between different components on the board, each component is shielded using an EMI coating or an EMI enclosure. Each of the walls within the microwave is made of a metallic sheet which prevents the microwaves from escaping.
Many electrical cables are also used to connect various devices and pieces of equipment, transmitting signals between the devices. A closed loop temperature monitoring system allows for continuous sputtering without exceeding the recipe set temperature points. The process of electromagnetic shielding utilizes conductive or magnetic materials to form a barrier which blocks electromagnetic fields from entering or exiting a particular region.
These metals can be used in many different forms including solid or perforated sheets, screens, and coatings.
We are committed to manufacturing high quality products to ensure that our customers get the exact product they need for their unique EMI specifications. By canceling the applied fields in this way, the incident fields are attenuated in the shielded region and reflected from the shielding surface.
EMI coatings typically consist of a carrier material loaded with a conducting metal, like copper or nickel, which together forms a metallic ink.
Most microwave ovens allow the user to see within the device using a perforated metal sheet.
Thus, the shielded device is isolated from the “outside world.” The external fields cannot penetrate the shield to interfere with the device, and any fields generated by the device cannot escape to interfere with other equipment.
This applies to both sides of the shield, attenuating fields generated outside and inside of the shield. This ink provides a flexible shielding method as it can be spray-coated to the inside of non-conductive enclosures or on wires. The perforations in the sheet are small enough to prevent the microwaves from escaping, but large enough to for visible light to pass through, allowing us to see inside.
Since wires by themselves can be susceptible to electromagnetic interference, this wire shielding allows electrical signals to be transferred between devices unaltered and uninhibited. However, the attenuation of these fields is dependent on several factors like the type shielding material, the thickness of the shield, the volume of the shielded region, and the frequency of the incident fields.
Additionally, for expanded metal and screen shields, any holes within the shield must be significantly smaller than the wavelength of the radiation being blocked.
