Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI

EMI and RFI shielding includes coatings, gaskets, enclosures, sealants, resins and other products or materials that block out electromagnetic interference (EMI) and radio frequency (RF) interference

Magnetic shielding includes products and raw materials for shielding instruments and equipment from magnetic fields. 

Product and component testing services is the evaluation of a finished product or component through performance in electrical, life, environmental exposure, dynamic, ergonomic or other specialized tests.  Also testing to standards such as UL 489, CE or MIL-STD 810.

Electrical and EMC testing services evaluate parts and products for electromagnetic compatibility (EMC), electromagnetic interference (EMI), radio frequency interference (RFI), dielectric properties, conductivity, electrostatic discharge (ESD), insulation resistance, and other electrical characteristics

PCB design and layout services providers generate schematics and CAD files for printed circuit boards.

Printed circuit board (PCB) fabrication services design and fabricate circuit boards. They differ from electronic manufacturing services, which populate and assemble boards. 

Computer-aided design (CAD) services assist in the computerized design, three-dimensional (3D) modeling, and printing and drafting of engineering components and assemblies.

EMI and RFI testers monitor the presence of unwanted electromagnetic and radio frequency radiation

Enterprise manufacturing intelligence (EMI) software provides real-time information about manufacturing processes. EMI software helps businesses optimize the performance of these processes and maximize yields

Switch boots protect switches from contaminants such as dirt, dust, gas, and liquids.  They are generally tough, pliable silicone rubber devices for toggle, pushbutton, rocker and rotary switches.

Gaskets are used to prevent fluid or gas leaks by providing a barrier between two mating surfaces.

Electrical resins and electronic compounds includes adhesives, greases, pads, stock shapes, tapes, encapsulants, potting compounds, thermal interface materials, and electrically conductive substances used in electrical, electronics, and semiconductor applications.

EMC Testers are devices used to test or monitor parts and products for electromagnetic compatibility (EMC).

Display filters and films are designed to filter, enhanced and/or protect monitors or flat panel displays (FPD).
