Tuling PCB EMI Shield
Tuling circuit board shields are designed to safeguard electronic components only on the PCB. We use conductive and magnetic sheet metals, e.g., stainless steel, nickel-silver alloy, etc., for our board-level shielding products.
A tin/nickel/copper/silver coating is added to increase the shielding effectiveness. Our PCB shields can absorb/reflect EMI/RFI up to 40dB from 100MHz to 1.5GHz.
We can achieve a ±0.01mm flatness tolerance with our high-end tooling and prototyping technology. All our PCB shields are IEC and RoHS compliant, and manufactured, maintaining ISO 9001:2015 guidelines.

Features of Tuling PCB RF Shield
Our circuit board shields are lightweight and take up less space.
You can remove and install Tuling PCB shields in a snap.
Tuling PCB shields are moderately corrosion resistant and have level 1 moisture sensitivity.
Our circuit board shields can smoothly operate in temperature from -40°C to +125°C.
PCB EMI shield Customization Options
Shapes: Tuling can manufacture shields for complex geometrical circuit boards, such as radii/circles shields for round boards.
Designs: We can cut recessed areas in the can to prevent short circuits and stamp ventilation for heat removal.
Sizes: Standardized size and height for PCB shields is 10X10 mm to 100 mm X 160mm and 1mm to 100mm, respectfully. Both the size and thickness can be customized depending on the attenuation level at Tuling.
Tuling PCB Metal Shield Materials
We use sheet metals with high electric conductivity, magnetic permeability, and solderability for circuit board shields. Our top choices are:
- Pre-tin plated steel
- Tinned steel
- Stainless Steel
- Pre-plated CRS
- Brass
- Nickel-Silver alloys
- Aluminum alloys
- Tin plated copper

Industry Standard PCB Shielding
Tuling circuit board shields pass on the industry standardized tests. A few to mention:
- EMC Compatibility: IEC 61000-4
- Thermal Shock: MIL-STD-883E
- Mechanical Shock: JEDEC JESD 22-B104-B
- Vibration: IEC 60068-2-64
- Bump: IEC 60068-2-29
- Accelerated Aging: 85°C / 85 RH
Our PCB RF shields easily fit on any circuit board due to the precise design. Key applications of board-level shields are seen in:
- Wireless modules: O-Link wireless communications devices, global navigation satellite systems (GNSS)
- Protects sensitive components: RF stages, ICs, oscillators and signal generators
- Military Components: Handheld Radios/ Drones/ Avionics/ Weapons Systems,
- Industrial Handheld Computers and Scanners
It is possible to chemically etch PCB shields. Precise and intricate designs can be achieved with this process. Chemically etched PCB enclosures are cost-effective and seamlessly fit on the circuit boards. The main disadvantages of this technique are the lengthy processing time and hazardous chemical exposure.
The installation process depends on the type of circuit board shields. For example, many surface mount and through-hole PCB shields require soldering to secure the connection. On the other hand, clip-on shields can be attached only by snapping the pins or clips over the board.
