PRODUCT CENTER
Find the shielding structure
your board needs.
MATERIALS & ENGINEERING
Choose materials around
your assembly.
Material, geometry and joining method work together.
Define them as one manufacturing specification.
NICKEL SILVER
Match the material to the way you assemble.
Specify the grade, thickness and condition alongside the forming and joining requirements. A nickel silver shielding can should be evaluated with its PCB interface and assembly process.
- Material grade and thickness
- Soldering and connection method
- Surface condition and drawing requirements
TINPLATE
Define the coating as well as the geometry.
For tin-coated steel shields, include thickness, coating and appearance requirements in the drawing. Review forming and the intended joining process together.
- Steel thickness and tin coating
- Forming and board attachment
- Appearance and surface condition
STAINLESS STEEL
Start with the grade and material condition.
The forming process, joining method and surface requirements depend on the specified stainless steel grade and condition. Confirm the combination through the drawing and sample review.
- Material grade and condition
- Formed geometry and dimensions
- Joining and surface treatment
ALUMINUM ALLOY
Balance the geometry, weight and connection.
Define the alloy grade and thickness first. Then review how the shield will be formed, attached and finished within the assembly.
- Alloy grade and thickness
- Can geometry and assembly method
- Connection and surface treatment
ZINC ALLOY
Choose the process around the actual part.
Specify the alloy grade and part geometry before discussing the forming route, connection and surface finish. The agreed drawing and sample define the manufacturing requirements.
- Alloy grade and dimensions
- Forming route and assembly fit
- Finish and inspection requirements
PHOSPHOR BRONZE
Build the material choice around the contact.
For spring clips and contact parts, review thickness, material condition, working position and mating dimensions together. Define the finish and inspection requirements for the intended assembly.
- Grade, condition and thickness
- Contact position and working space
- Surface finish and mating inspection

APPLICATIONS
Different boards.
Different shielding requirements.
01 / WIRELESS & COMMUNICATION
RF & Wireless Modules
Plan the shielding boundary around the module layout and assembly requirements.
02 / CONSUMER ELECTRONICS
Mobile & Consumer Devices
Review enclosure height, connection and access within the available board space.
03 / AUTOMOTIVE ELECTRONICS
Automotive Modules
Define the module drawing, operating conditions and project validation requirements.
CUSTOM MANUFACTURING
From your drawing
to a manufacturing plan.
Review the Design
Discuss manufacturability, the forming route, assembly interfaces and critical dimensions.
Validate a Sample
Standard samples: 3–5 days. Expedited sampling: 48 hours. Tooling and sample production: 7–10 days. Sample fees apply; volume production and delivery are scheduled separately.
Confirm & Produce
After sample approval, confirm the drawing revision, inspection requirements and packaging for production.
QUALITY & DOCUMENTATION
Trace the requirements.
Review the evidence.
Quality and environmental management system certificates and material test reports are available for review. Check each document's scope against your project requirements.

STRUCTURE SELECTION
One piece or two? Start with access and assembly.
Compare the structures against maintenance needs, space and board attachment.

PROJECT PREPARATION
What should you prepare for a custom shield?
Gather dimensions, materials, quantities and assembly information before the design review.
Prepare your project brief ↗IN-HOUSE TOOLING
Tooling quality starts
with the part drawing.
A shield needs more than the right outline. Its formed geometry, assembly interfaces and inspection requirements should guide the die design from the start.
100+die sets / month
Overall factory tooling output.
Project scope and schedules are agreed individually.
- Drawing-led die development
- In-house tooling connects die design and CAD/CAM simulation with stamping, surface treatment and final inspection.
- Quality verified on the sample
- Paid samples are supplied with a full dimensional inspection report. Critical dimensions, datums and mating features are agreed against your drawing.
- Inspection through production
- Incoming, in-process and outgoing inspection support part quality. Our measurement equipment includes 2.5D vision systems, CMMs and profile projectors; the project determines the checks needed.
Tooling and sample production: 7–10 days. This covers the sample stage; mass-production delivery is agreed separately.
