Stamped Nickel Silver and Stainless PCB RF Shields
These are RF shields and shielding cans for printed circuit boards, stamped from nickel silver (copper-nickel-zinc alloy), stainless steel or tin-plated steel. They come as one-piece cans or two-piece frame-and-lid designs, with optional vent holes and pick-up pads for SMT placement. They are made for electronics designers who need custom shield shapes to suppress EMI around RF circuits.

Manufacturing
How we make this part
Process, material options and inspection for stamped nickel silver and stainless pcb rf shields.
Prototype shields are laser cut or chemically etched from flat sheet, then bent, which avoids tooling while the layout is still changing. For production, progressive stamping dies blank, form and cut the shield in one press cycle. Two-piece designs use a soldered frame with a snap-on lid, so the lid can be removed for rework or tuning without desoldering.
Nickel silver, typically about 0.15–0.3 mm thick, is solderable without plating and resists corrosion, making it the most common shield material. Stainless steel is stronger and cheaper but generally needs plating to solder well. Tin-plated steel is low cost and solderable. Material choice also affects shielding effectiveness across frequencies, so it should be confirmed by testing.
Flatness of the solder edge, overall height and outline dimensions are measured, because a warped edge leaves gaps in the solder joint. The first-off from each die is inspected, and coplanarity is checked on samples throughout the run. Typical uses include Wi-Fi and Bluetooth modules, cellular modems, GPS receivers, automotive radar boards and IoT devices.
FAQ
Frequently asked questions
Why is nickel silver popular for RF shields?
Nickel silver solders easily without additional plating, resists tarnish and is easy to form at thin gauges. It offers good shielding for many common RF frequencies. Stainless steel is a lower-cost alternative but usually needs tin or nickel plating to solder reliably.
Should I choose a one-piece or two-piece shield?
A one-piece can is cheaper and seals well, but must be desoldered for rework. A two-piece frame-and-lid design costs slightly more, yet the lid can be removed for inspection, tuning or repair. Two-piece designs are common during development and on boards that need service access.
