What is EMI/RFI shielding?
EMI shielding, known by its full title of electromagnetic shielding, but often shortened to RFI shielding or EMC shielding, is the use of manufacturing techniques and materials to protect signals from disruption from external electromagnetic signals, alongside preventing generated signals from interfering with the components installed around it.
For shielding on PCBs (known as Board Level Shielding or BLS) shielding normally comes in the form of a PCB shielding can or enclosure produced from a conductive or magnetic material to isolate electrical devices from their surroundings.
Though PCB shielding cans can be manufactured in a variety of ways, our market-leading EMI/RFI shielding photo etching service offers many distinct advantages which improve functionality and lower cost.
Benefits of etching EMI/RFI Shielding at PCB level
Low set-up costs & fast delivery
We use low-cost digital tooling, reducing time-to-market. Delivery can be from as little as a few days, and even quicker for urgent requirements.
Board level shielding can complexity without cost
With chemical etching, there is no limit to profile complexity or aperture array.
We can incorporate bend lines so PCB shielding cans can be formed by hand, removing the need for hard form tooling, and add part numbers or logos at no additional cost.
EMI shielding materials and finishing
Nickel silver is the most cost-effective material choice for RFI screening cans as it can be soldered, will not oxidise and requires no additional plating.
Standard materials such as brass and mild steel are also available from stock, as well as in-house forming, assembly, spot welding, and tin, silver, nickel and gold plating.
