TWO-PIECE SHIELDING CAN
Two-Piece EMI Shielding Can
Review frame-to-lid fit, contact areas and the space needed to remove the lid as part of the complete PCB assembly.
A matched frame and removable lid with access for debugging, inspection and rework.
Use the image as a design reference. The agreed drawing and sample define the supplied part.
STRUCTURE & FUNCTION
Choose the structure
around your design.
A two-piece shielding can combines a frame and a lid, with frame mounting and lid removal specified separately. Treat their fit, contact locations and opening clearance as one assembly when selecting the design.
Engagement and contacts defined together
Choose snap-fit or spring-contact features with clearances, contact locations and retention requirements specified for the assembly.
Removal included in the design
Specify lid handling direction, tool clearance and service frequency alongside the part geometry.
CUSTOMIZATION DETAILS
Turn design requirements
into drawing details.
Share dimensions, mating-part information and operating requirements so we can review the manufacturing and inspection approach.
| Design item | What to discuss | Information to provide |
|---|---|---|
| Frame and mounting interface | Define the frame around the PCB boundary, locating, soldering or other attachment method | Frame drawing, PCB mating geometry and mounting method |
| Lid and frame fit | Agree on the lid outline, mating clearance and engagement locations together | Frame and lid drawings with a complete assembly revision |
| Contact features | Select snap-fit or spring contacts as designed and define their working areas | Contact locations, mating parts and inspection tasks |
| Opening and service access | Review removal direction and operating clearance for debugging or rework | Tool clearance, removal sequence and service frequency |
| Material and finish | Specify material, thickness and finish for the frame and lid individually | Material and treatment requirements for both parts |
| Assembly samples | Charged: standard samples 3–5 days; expedited sampling 48 hours; tooling and sample production 7–10 days. Sample stage only; volume production and delivery excluded. Confirm a suitable process | Matched quantities, mating assembly and removal or contact tasks to validate |

DESIGN CONSIDERATIONS
How will the shield
fit into your assembly?
Start with the module location, installation method and access requirements, then resolve the detailed fit.
Read the related design guide ↗Access during development
Define the measurement area, opening direction and tool clearance when enclosed components need probing or adjustment.
Product rework
If the frame is to remain installed, specify how the lid is lifted, the operating boundary and nearby components requiring protection.
A new lid for an existing frame
Provide the current frame revision, a sample or drawings, with engagement, contact and retention requirements.
DESIGN CONSIDERATIONS
Review the structure and assembly
- Identify the frame and lid pairing on the part and assembly drawings.
- Check retention and contact areas with the mating parts before finalizing the geometry.
- Agree on lid-removal direction and tool clearance before ordering samples.
DRAWINGS & REQUIREMENTS
Information to provide with your drawing
- Part and assembly drawings showing the frame and lid pairing, with units and revision details.
- Dimensions and mating-part information for retention and contact areas.
- Requirements for lid-removal direction and tool clearance, together with sample and batch quantities.
TOOLING & SAMPLE VALIDATION
Tooling decisions behind
Two-Piece EMI Shielding Can.
Ruishuo makes tooling in-house, connecting die design and CAD/CAM simulation with stamping and inspection. The tooling route for your part is reviewed against the agreed drawing, material and assembly requirements.
Develop the frame and lid as a mating pair.
For a two-piece or removable shield, the tooling review includes the interface between the frame and lid. A lid that matches the nominal outline may still need adjustment at its engagement points. Sample review should therefore cover the assembled pair, with any removal and retention requirements agreed for the intended use.
- Define frame seating, lid overlap and engagement locations on the drawing.
- Specify the mating component and any required insertion, removal or retention checks.
- Confirm access requirements and edge conditions before accepting the sample pair.
Use the sample report to close the drawing review.
Paid samples include a full dimensional inspection report. Ruishuo's inspection equipment includes 2.5D vision measurement systems, CMMs and profile projectors; measurement methods and any additional functional checks are selected for the project. Incoming, in-process and outgoing inspections support the agreed requirements as the part moves into production.

PRODUCT FAQ
Questions about
Two-Piece EMI Shielding Can?
Bring the available drawing and assembly details, even if some dimensions or material choices are still open.
Discuss your project ↗Are lids with the same outline interchangeable?
Engagement, clearances and contact locations also have to match. Review the new lid against the existing frame in one assembly revision, then validate with matched samples.
Must the frame be removed to open the shield?
A frame-and-lid design can be developed around leaving the frame in place while removing the lid. Confirm the removal method and operating clearance for the mounting arrangement.
How do two-piece and split-type shields differ?
Those names may refer to the same frame-and-lid approach. Compare the actual fit, contact structure and removal method to distinguish the designs.
