EMI and RFI are disturbances in electrical equipment caused by an external source’s electromagnetic emissions. Although EMI and RFI are used interchangeably, the difference between the two is simply that EMI includes any frequency of electrical noise, while RFI refers only to specific subsets of electrical noise (i.e. radio frequency spectrum).
EMI (Electromagnetic Interference) and RFI (Radio-Frequency Interference) Shieldings are designed to limit the number of electromagnetic waves in a particular space or device to prevent interference with other devices. EMI shields, sometimes referred to as shielding enclosures, use conductive or magnetic materials in order to block the waves from entering or leaving a device.
Microphoto provides photochemically etched EMI/RFI Shieldings solutions commonly used for a wide range of applications. Examples include:
At Microphoto, our years of experience play a role in manufacturing EMI/RFI Shielding products with the utmost standard of quality and care. Electromagnetic Interference (EFI) and Radio Frequency Interference (RFI) shielding products block electromagnetic signals from reaching electronic components.
Below are two types of shielding products we manufacture.
With years of experience in machining with various metal alloys, Microphoto can manufacture your EMI/RFI Shielding to meet your needs. To name a few, below are common materials used in EMI/RFI Shielding.
Microphoto can manufacture photochemically etched EMI/RFI Shieldings for a variety of industries, such as:
At Microphoto, we provide customers with high-quality and high-precision parts through our photochemical machining process.
Photochemical machining allows for the manufacture of finely detailed and complex designs that could not be manufactured using other more traditional methods such as stamping. Fine bend lines can be created in the shield to aid in easy hand forming by our team or yours.
Our process results in parts that are burr-free, and without any recast layers that can result from laser cutting or Wire EDM processing. We can also manage any post-production secondary requirements such as passivation, heat treating, plating, or non-destructive testing.
