Product Overview

Two-Piece Shielding CanDesign Structure

Two-piece design employs separated frame and cover structure, optimizing assembly, rework, and cost-effectiveness.

Two-Piece EMI Shielding Can Frame Cover PCB Board

Frame Welding + Cover Snap-Fit

Frame is welded directly to PCB as the shielding foundation. Cover connects to the frame through precision snap-fit, providing tight, reliable connection.

Rework-Friendly Design

Cover requires no desoldering and can be easily unsnapped for internal rework and reassembly, significantly reducing rework costs.

SMT Process Compatible

Frame design accommodates SMT pick-and-place processes. Pad layout follows industry standards and is fully compatible with mainstream pick-and-place machines and reflow soldering.

Multi-Cavity Option

Frame supports internal partition design for multi-region RF isolation within a single shielding can, suitable for complex circuit layouts.

Frequently Asked Questions

About Two-Piece Shielding CoversCommon Questions

What is the difference between two-piece and one-piece shielding covers?
+
Two-piece consists of a frame and cover. The frame is welded to the PCB, and the cover snaps on for easy rework. One-piece is deep-drawn as a single unit, offering higher shielding efficiency but difficult rework. Two-piece suits frequent maintenance needs, while one-piece fits space-constrained devices.
How does the two-piece cover connect to the frame?
+
We use precision snap-fit design. The cover has flexible snap fingers that lock into snap-fit positions on the frame perimeter for tight, reliable connection while allowing quick manual disassembly. The snap positions are precisely located for repeated assembly without product damage.
What surface treatments are supported for two-piece covers?
+
We support multiple surface treatment options: Tin plating (easy soldering), Nickel plating (corrosion resistance), Gold plating (high reliability), Plastic coating (insulation), and Anodizing (aluminum). Select the appropriate treatment based on your application environment and soldering process.
Can non-standard sizes and multi-cavity designs be customized?
+
Completely supported. We can customize two-piece covers to any size based on your PCB layout and circuit design requirements. Multi-cavity designs with internal partitions are available to isolate multiple RF regions. Provide PCB dimensional drawings, and our DFM engineers will recommend the optimal solution.
Will frame welding affect the cover?
+
Frame welding temperature and the cover’s spring material are fully compatible. We recommend installing the cover after frame welding is complete and cooled to preserve snap-fit spring properties. For high-temperature applications, notify us in advance so we can select higher-temperature spring materials.
What is the delivery timeline?
+
Standard two-piece cover samples: 7 days. Batch production: 3-4 weeks. Custom non-standard products: 10-15 days sampling (depends on complexity). We offer expedited services to meet your project timelines.
