Two-Piece EMI Shield
Bring both part drawings and the assembly view into the review. Confirm contact fit, access needs and the removal method together.
Use the image as a design reference. The agreed drawing and sample define the supplied part.
DESIGN CONSIDERATIONS
Review the structure and assembly
- Identify the two-part assembly drawing and revisions on the part and assembly drawings.
- Check frame-to-lid fit and contact method with the mating parts before finalizing the geometry.
- Agree on removal frequency and tool access before ordering samples.
DRAWINGS & REQUIREMENTS
Information to provide with your drawing
- Part and assembly drawings showing the two-part assembly drawing and revisions, with units and revision details.
- Dimensions and mating-part information for frame-to-lid fit and contact method.
- Requirements for removal frequency and tool access, together with sample and batch quantities.
Sampling before production
Agree on the drawing, manufacturing route and sample scope first. Use the sample to check fit, assembly and the tests required by your project, then confirm the production drawing, inspection plan and packaging.
Samples are paid. Standard samples: 3–5 days. Expedited sampling: 48 hours. Tooling and sample production: 7–10 days. These are sample-stage timings and do not include mass-production delivery; availability and the schedule are confirmed for each project.
TOOLING & SAMPLE VALIDATION
Tooling decisions behind
Two-Piece EMI Shield.
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.
