What is EMI shielding?
Electromagnetic shielding, often shortened to EMI shielding, is used to prevent electromagnetic signals such as radio frequencies (RF) from interfering with sensitive electronic devices or equipment.
At PCB board level, EMI shielding normally comes in the form of a PCB shielding can produced from a conductive or magnetic material to isolate electrical devices from their surroundings.
Chemical etching PCB shielding cans
Though PCB shielding and screening cans can be manufactured in a variety of ways, our market-leading EMI shielding photo etching service offers many distinct advantages which improve functionality and lower cost.
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 components 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 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.
