Welcome to PEI, your go-to source for specialized EMI & RF Shielding solutions for board-level applications. With over 50 years of experience in the precision photo etching industry, we offer custom-designed shields that not only protect your electronic components from electromagnetic and radio frequency interference but also ensure optimal performance, reliability, and safety. Our rapid turnaround times and cost-effective solutions provide manufacturers with a competitive edge in launching new products, making us an industry leader in custom shielding designs.
The Role of EMI & RF Shielding
Understanding the distinct roles of EMI and RF/RFI Shielding is pivotal for ensuring the optimal performance and reliability of electronic systems. Our innovative Control Depth Etch (CDE) fold line technology allows us to create 3-dimensional EMI/RF shield solutions from flat sheets, significantly reducing tooling costs and delivery cycle times. CDE fold lines create an easy way to manually bend your custom designs accurately and at various angles, avoiding the expense of hard tooling and the delivery timing associated with it.
| Aspect | EMI Shielding | RF/RFI Shielding |
| Primary Function | Protects against electromagnetic interference | Protects against radio frequency interference |
| Importance | Critical for maintaining signal integrity and preventing system malfunctions | Essential for high-frequency applications like telecommunications |
| Applications | Aerospace, healthcare, military, and more | Telecommunications, wireless devices, and more |
| Material Considerations | Conductivity, magnetic permeability, and thickness are key | Material conductivity and shield geometry are crucial |
| Custom Solutions | PEI offers tailored EMI shields to meet industry standards | PEI provides custom RF/RFI shields for a wide range of frequencies and uses |
Two-piece Design (Cover & Fence)
• We can design a board level “Fence” with a mating “Cover”
Standard base materials include:
• Brass
• Tin
• Tin-lead
• Nickel
• Nickel/Silver
• Copper
• Cold-rolled steel
** All of which can be provided with solder-able plating
The most common material choice is Nickel-silver!
• Nickel/Silver (Ni/Ag) doesn’t require additional finishing because it is already solder-able
EMI/RFI Shielding can be provided in unformed (Flat) condition which can greatly reduce shipping costs and inventory storage space until your shield is ready for final assembly. This also reduces PEI’s costs to you! PEI can provide tape & reel packaging for automated assembly if required.
Our innovative technology and extensive etching capabilities allow us to manufacture reliable, easy-to-use shielding at low cost and with fast deliveries. Let our Engineers apply this unique CDE fold technology to maximize your EMI/RF shielding needs!
