Precision Micro specialises in custom, medium-to-production volume EMI/RFI shielding manufacture for a wide range of high-tech applications, including implantable defibrillators, surveillance UAVs and marine vessel positioning.
Whilst EMI/RFI shielding can be manufactured in a variety of ways, photo etching offers distinct advantages, improving functionality and lowering cost.
Low set-up costs
Digital photo-tooling offsets expensive press tools which can run into hundreds of thousands of pounds. It also ensures design iterations can be handled quickly and economically during prototyping, reducing time-to-market.
With photo etching there is no limit to profile complexity or aperture array, allowing easy partitioning around circuitry.
We can incorporate bend lines so components can be formed by hand, removing the need for hard form tooling. The photoresist used to mask the component during photo etching acts as an excellent electrical insulator and can be selectively applied to reduce arcing. We can also add part numbers and logos at no additional cost.
Materials and finishing
Nickel silver is the most cost-effective material choice for shielding designs. It can be soldered, will not oxidise and requires no additional plating.
Precision Micro offers a variety of in-house assembly techniques, including forming and spot welding for single source supply. We also offer tin, silver, nickel and gold plating.
