PCB SHIELDING CANS
In an increasingly wireless world, the "invisible" battle for signal clarity is fought on the surface of the printed circuit board (PCB). As devices become smaller and frequencies higher, protecting sensitive components from electronic noise is no longer optional—it is a design mandate.
​
With over six decades of global supply expertise, we specialize in producing custom PCB shielding cans that ensure your electronics perform flawlessly, regardless of how crowded the airwaves become.

Understanding EMI/RFI: The Need for Board Level Shielding
Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) are the "noise" of the electronics world. This interference can come from external sources—like cell signals and power lines—or from components on the same board "talking" to each other unintentionally.
​
Board Level Shielding (BLS) acts as a physical fortress. By using conductive or magnetic enclosures, known as shielding cans, we isolate critical components. This achieves two goals:
​
-
Defense: Protecting sensitive parts from external disruption.
-
Containment: Preventing noisy components from interfering with nearby electronics.

The Chemical Etching Advantage: Speed, Flexibility, and Precision
Traditional stamping methods often require expensive, hard-to-modify steel molds. We utilize photochemical etching, an industry-leading process that offers a smarter path from prototype to mass production.
​
-
Zero Tooling Costs: We eliminate the need for time-consuming mold preparation. This means shorter lead times and the ability to move from design to physical part in days, not weeks.
-
Design Without Limits: Need ventilation holes to manage heat? Or perhaps access ports for tuning? With chemical etching, complex features, part numbers, logos, and even fold lines for easy hand-forming are integrated during the process at no additional cost.
-
Stress-Free Manufacturing: Unlike mechanical stamping, etching doesn't apply force to the metal, ensuring the material properties remain perfectly intact.
​
Material Excellence and Post-Process Versatility
Choosing the right material is the first step in effective shielding. While we stock standard brass and mild steel, our specialist recommendation often points toward Nickel Silver.
​
Why Nickel Silver? It is the "triple threat" of shielding materials: it is highly cost-effective, easily solderable, and naturally resists oxidation. Most importantly, it often eliminates the need for expensive post-plating.
​
Comprehensive In-House Services
To provide a seamless experience, we manage the entire lifecycle of your shield can under one roof:
​
-
Forming & Assembly: Precision bending and spot welding for structural integrity.
-
Custom Plating: When specific conductivity or environmental resistance is required, we offer Tin, Silver, Nickel, and Gold finishes.
