Choose the question you need to resolve next
The most useful information depends on the project stage. Early design discussions focus on structure and available space. Drawing review sets dimensions and datums. Sampling needs a validation scope, while order preparation brings materials, inspection and packaging into one approved input set.
These resources help organize engineering discussions. The project drawing, sample approval and agreed verification methods remain the basis of the actual design. Product photographs illustrate existing structures without defining unlisted specifications.

Choosing a Structure
Define access, PCB space, attachment and circuit areas before reviewing single-body shields, removable lids, multiple cavities or clips.
Explore Custom Engineering ↗Preparing the Drawing
Bring the part drawing, mating relationships and critical datums together. Mark fixed requirements, reviewable options and the current revision.
Use the Drawing Checklist ↗Planning Samples and Production
Define the sample checks separately from volume inputs, including material, finish, records, assembly supply and quantity.
Review Sample Validation ↗Six items for a clearer manufacturing brief
| Topic | Useful project information | Related resource |
|---|---|---|
| Structure | Coverage area, internal space, lid access and attachment | Custom engineering |
| Drawing | Revision, units, critical dimensions and mating parts | Drawing and DFM review |
| Materials | Base metal, thickness, finish and functional interfaces | Materials engineering |
| Samples | Validation objectives, quantity and acceptance method | Samples and validation |
| Quality documents | Inspection items and required document scope | Quality control |
| Assembly supply | Handling, orientation, identification and protection | Packaging and delivery |
Keep structure, material and application terms distinct
A two-piece shield describes a frame-and-lid structure. Stainless steel describes a material direction. A smartphone shield describes an application. These terms answer different questions; they should be combined into a clear part definition rather than treated as interchangeable specifications.
BB means baseband and identifies the baseband circuit area covered by a shield. RF identifies a radio-frequency circuit area. Both names still need a structural definition, space envelope, material and attachment method. The application name does not establish a particular fit or performance result.
Make the next revision easy to review
When the height, opening, partition, attachment feature, material or finish changes, record the revision and affected mating items. Separate requirements that remain approved from those needing new assessment. This prevents different drawings or email threads from becoming competing production inputs.
Samples are charged. The confirmed sample plan may use standard samples in 3–5 days, expedited sampling in 48 hours, or tooling and sample production in 7–10 days. Volume production and delivery are reviewed separately. Use the contact form to describe the current revision and the question you need resolved.
