custom Two Pieces Custom Shield Frame and Cover

A two-piece shield consists of:

• Shield Frame (Base): A metal frame mounted directly to the PCB, typically soldered or mechanically fastened. It creates a defined perimeter around the area to be shielded.

• Shield Cover (Lid): A removable or snap-fit top that fits securely onto the frame. It provides complete EMI coverage while allowing for rework, inspection, or testing after assembly.

This modular design offers an ideal balance between performance and practicality. It enables easy access to components without desoldering the entire shield, saving time during prototyping, testing, and repair.

Key Features and Benefits

✅ Superior EMI/RFI Shielding

Our two-piece shield systems provide high shielding effectiveness across a broad frequency range, reducing crosstalk, signal leakage, and external noise interference.

✅ Easy Access for Rework and Testing

The removable cover simplifies debugging, inspection, and maintenance — especially useful in development environments or devices requiring field servicing.

✅ Fully Customizable

At TMN, every frame and cover is tailored to your PCB layout, height requirements, opening features (vents, cutouts), and mechanical constraints. We support single and multi-cavity configurations.

✅ Durable and Robust Construction

Fabricated using high-performance materials like stainless steel, tin-plated steel, copper alloys, or nickel silver, our shields offer long-lasting mechanical strength and corrosion resistance.

✅ Multiple Assembly Options

We offer press-fit, snap-on, solderable, and mechanically fastened options — depending on your production needs and product design.

✅ Cost-Effective for High Volume

With automated stamping and forming processes, our two-piece shields are efficient and economical even for large production runs.

Common Materials We Use

We fabricate shield frames and covers using a variety of metals, depending on your EMI requirements, environmental conditions, and budget:

• Tin-Plated Steel: Cost-effective with good solderability and conductivity

• Stainless Steel: Excellent strength and corrosion resistance

• Copper and Copper Alloys: High conductivity for demanding EMI environments

• Nickel Silver: Non-magnetic, corrosion-resistant, and highly conductive

Each material can be further finished with coatings such as tin, nickel, or silver to enhance conductivity, prevent corrosion, or improve solderability.

Applications

Two-piece custom shield frames and covers are ideal for protecting components and circuit zones in:

• Telecommunications Equipment
  Protects RF circuits, basebands, and transceiver modules from signal distortion.

• Consumer Electronics
  Smartphones, tablets, wearables, and smart home devices all benefit from compact, accessible shielding solutions.

• Medical Devices
  Ensures sensitive sensors and signal processing modules comply with strict EMI standards.

• Automotive & EV Systems
  BMS (battery management systems), ECUs, and infotainment systems need shielding that’s durable and serviceable.

• Aerospace and Defense Electronics
  Mission-critical systems require high-performance shielding with proven mechanical and electrical reliability.

• IoT and Industrial Controls
  Small embedded modules, controllers, and industrial sensors are often densely packed and EMI-sensitive.
