BB EMI Shield
Confirm coverage, mounting and mating-part requirements from the drawing.
Use the image as a design reference. The agreed drawing and sample define the supplied part.
DESIGN CONSIDERATIONS
Define the shielding requirement
- Define the coverage boundary shown on the drawing in terms that can be checked against the drawing.
- Review the mounting interface and mating parts with the mating parts and installation method.
- Agree on the specified material and inspection requirements before selecting a sample process.
DRAWINGS & REQUIREMENTS
Information to include with your inquiry
- The part's intended use and the information available for the coverage boundary shown on the drawing.
- Drawings, mating-part information or a reference sample for the mounting interface and mating parts.
- Requirements for the specified material and inspection requirements, including 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
BB 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.
Connect the baseband layout to the tooling requirements.
A BB shield covers the baseband circuit area. Its tooling review should use the actual board outline, component heights and grounding or mounting interfaces for that area. The BB label does not define a standard die, material or guaranteed shielding performance. The drawing and sample need to establish the mechanical fit before the customer validates the complete electronic assembly.
- Provide the baseband area layout and the component-clearance envelope.
- Identify grounding, soldering or frame-to-lid features shown in the design.
- Check the mechanical sample against the mating board; validate EMI behavior in the system.
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.
