What Are PCB Shielding Cans?

PCB shielding cans are metal enclosures or covers installed over selected areas of a printed circuit board to help control electromagnetic interference. They are commonly used to isolate sensitive electronic circuits from surrounding components and reduce unwanted electromagnetic coupling within compact electronic devices.

Modern electronic products often contain multiple circuits operating in close proximity. Wireless communication sections, processors, power circuits, RF components, and signal-processing modules may generate or receive electromagnetic energy. Without appropriate electromagnetic compatibility design, interference between these circuits can affect device performance, signal quality, or communication stability.

A PCB shielding can provides a conductive physical barrier around selected components. Depending on the design, it may be installed directly onto a PCB, attached to a separate shielding frame, or integrated into a larger electronic enclosure. Some shielding cans are manufactured as one-piece components, while others use a separate frame and removable cover.

The structure and installation method depend on the electronic module, PCB layout, available space, component height, grounding design, and required shielding performance. For this reason, PCB shielding cans are usually customized rather than selected solely from standard dimensions.

For OEM electronics manufacturers, a suitable shielding can should satisfy several requirements at the same time: accurate fit, appropriate material properties, reliable assembly, suitable surface finish, and performance consistent with the intended electromagnetic compatibility design.

Custom PCB Shielding Cans for Electronic Manufacturers

PCB shielding cans are often designed around a specific circuit layout. Their dimensions, wall height, cutouts, mounting points, and forming features must match the PCB and the components being protected. Even small dimensional differences can influence assembly clearance or the contact between the shielding structure and its mounting frame.

SinoStamp supports drawing-based PCB shielding can manufacturing for customers with established product designs and technical documentation. We can review the proposed geometry and manufacturing requirements before production to identify relevant tooling and process considerations.

Common customization options include:

• Custom length, width, and height based on PCB dimensions.
• Different wall heights to accommodate electronic components.
• Customized cutouts for connectors, cables, and other interfaces.
• Formed corners, flanges, tabs, and mounting features.
• Custom openings and relief features based on circuit layout.
• Material and thickness selection according to application requirements.
• Surface finishes for appearance, corrosion resistance, or assembly compatibility.
• One-piece or multi-component shielding structures, subject to design feasibility.

Customers can provide 2D drawings, 3D CAD files, physical samples, or preliminary design information. A complete drawing with dimensions and tolerances is preferred for quotation and manufacturing evaluation. If a physical sample is supplied, its critical features and interface requirements should also be identified.

Materials for Custom PCB Shielding Cans

Material selection has an important influence on shielding performance, mechanical strength, forming behavior, corrosion resistance, and manufacturing cost. Different metals offer different combinations of electrical conductivity, magnetic properties, and workability. The appropriate material depends on the target frequency range, shielding structure, assembly design, and operating environment.

Tinplate PCB Shielding Cans

Tinplate is a steel sheet coated with a thin layer of tin. It combines the structural strength of steel with a tin-coated surface and is commonly considered for electronic metal components. Its formability makes it suitable for various stamped shielding can designs.

Tinplate may be used for PCB shielding cans that require a balance between mechanical stability, manufacturing feasibility, and cost. It can be processed through cutting, punching, stamping, and forming operations to produce customized metal covers and enclosures.

When specifying tinplate, customers should confirm the base steel grade, tin coating requirements, sheet thickness, and surface condition. These factors can influence forming performance, soldering compatibility, corrosion resistance, and the final appearance.

Stainless Steel PCB Shielding Cans

Stainless steel offers corrosion resistance and mechanical strength. It may be suitable for shielding structures where durability, structural stability, or resistance to environmental exposure is important.

Different stainless steel grades have different forming characteristics, strength levels, and magnetic properties. The selected grade should be evaluated according to the required geometry and application. For thin-walled shielding cans, forming conditions and material springback should also be considered.

Stainless steel is not automatically the best material for every shielding application. Electrical conductivity and magnetic behavior vary from those of copper and other metals. Customers should select the grade based on the actual engineering requirements and validate the completed structure where necessary.

Copper PCB Shielding Cans

Copper is known for its high electrical conductivity and is widely used in electrical and electronic applications. It may be suitable for PCB shielding cans where conductivity is an important material consideration.

Different copper grades and tempers have different mechanical properties and forming characteristics. For custom deep-drawn or stamped shielding components, the selected copper specification should be reviewed together with the geometry, material thickness, and forming requirements.

Although copper offers high electrical conductivity, finished shielding performance also depends on enclosure design, contact resistance, grounding, seams, and frequency. A copper shielding can should therefore be evaluated as part of the intended electronic assembly.

Nickel Silver PCB Shielding Cans

Nickel silver is a copper-nickel-zinc alloy used in selected precision metal and electronic component applications. It offers a combination of mechanical properties, surface appearance, and corrosion resistance that may be suitable for certain shielding can designs.

Nickel silver does not contain silver as a precious-metal coating. Its characteristics depend on the specific alloy composition and material grade. Customers should identify the required grade and thickness when requesting a quotation or sample.

Material Selection for Different PCB Applications

There is no single material that is suitable for every PCB shielding can. A high-conductivity material may be desirable for some designs, while another application may prioritize mechanical stiffness, corrosion resistance, forming performance, or cost efficiency.

Before confirming a material, OEM customers should consider:

• The operating frequency range of the electronic circuit.
• The target shielding effectiveness and applicable test conditions.
• Electrical conductivity and magnetic characteristics.
• Required material thickness and mechanical strength.
• Deep drawing and bending requirements.
• Corrosion exposure and operating environment.
• Grounding, soldering, and electrical contact requirements.
• Surface finishing and compatibility with PCB assembly.

Deep Drawing and Precision Stamping for PCB Shielding Cans

Sunny-1002 supports manufacturing processes including deep drawing, precision stamping, bending, and forming. The suitable process depends on the shielding can's depth, geometry, wall structure, corner radius, material characteristics, and production quantity.

Deep Drawing

Deep drawing is a metal forming process used to transform a flat sheet metal blank into a three-dimensional shape through a punch and die. It is suitable for certain shielding can designs that require deeper walls or a formed enclosure structure.

The deep drawing process can reduce the need for multiple separate parts in suitable designs. However, the feasibility of deep drawing depends on material ductility, thickness, draw depth, corner radius, blank dimensions, and forming conditions.

For electronic shielding cans, dimensional consistency and wall geometry are important. The tooling design should consider material flow, possible thinning, wrinkling, cracking, and dimensional variation. These factors become particularly important for small components with relatively thin walls.

Precision Stamping

Precision stamping is used to produce accurate profiles, mounting features, cutouts, and other details. It may involve blanking, punching, piercing, and other operations performed using customized dies.

For PCB shielding cans, precision stamping can create locating features, openings, tabs, and mounting details required by the electronic assembly. Tooling accuracy and appropriate punching clearance help maintain dimensional consistency and edge quality.

Bending and Forming

Bending and forming operations create the required walls, flanges, corners, and other three-dimensional features. They are commonly used for shielding cans that are manufactured from folded sheet metal or require multiple formed sections.

Material thickness, bend radius, springback, forming direction, and the sequence of operations can influence the final dimensions. These factors should be evaluated during process planning to achieve the required shape and assembly fit.

Multi-Stage Forming

Some PCB shielding cans require more than one forming operation to achieve the final geometry. Multi-stage forming may be considered when the part includes deeper walls, complex corners, multiple cutouts, or other features that cannot be produced reliably in a single operation.

The appropriate process should be selected after reviewing the engineering drawing and expected order volume. For new projects, prototype evaluation can help identify potential forming and assembly issues before regular production begins.

Customized Cutouts and Structural Design

One of the main requirements in PCB shielding can manufacturing is customization of the enclosure geometry. Electronic modules often contain connectors, cables, antenna interfaces, mounting points, and components that require specific clearance. The shielding can must accommodate these features without interfering with the intended assembly.

Connector and Cable Cutouts

Some shielding cans require openings for connectors, cable routing, or external interfaces. The location and dimensions of these cutouts should be based on the PCB layout and mechanical assembly requirements.

Component Clearance Openings

PCB assemblies may contain components with different heights or special installation requirements. A shielding can may need localized openings or customized wall geometry to provide the required clearance. The design should also consider whether these openings affect the intended shielding structure.

Mounting Tabs and Positioning Features

Mounting tabs, locating features, and formed edges can help position the shielding can during assembly. Their dimensions and locations should be coordinated with the PCB or shielding frame design.

Corner and Wall Geometry

Corner radius, wall height, flange width, and overall enclosure geometry influence both manufacturability and assembly compatibility. For deep-drawn components, corner design and material flow require particular attention during tooling development.

Customers are encouraged to provide the PCB outline and relevant component height information where possible. This helps the manufacturer understand the mechanical interfaces and evaluate the shielding can's design more accurately.

Surface Finishing Options for PCB Shielding Cans

Surface finishing can influence appearance, corrosion resistance, electrical contact behavior, solderability, and compatibility with the customer's assembly process. Sunny-1002 supports several surface finish options according to the selected base material and project specifications.

Bright Tin Plating

Bright tin plating provides a bright metallic surface and may be selected for electronic components where tin finishing is required. Depending on the design and assembly process, tin plating may also be considered for solderability or electrical contact requirements.

Customers should specify the required plating thickness, surface appearance, and relevant technical standards. Plating requirements should be reviewed together with dimensional tolerances and assembly clearances.

Matte Finish

A matte surface finish provides a non-glossy appearance and may be selected for specific component or product requirements. The final appearance depends on the base metal and finishing process. Approved samples or surface references can help establish the required visual standard.

Anti-Tarnish Treatment

Anti-tarnish treatment may be used for selected metal surfaces to help reduce discoloration during storage and handling. The treatment should be compatible with the base material and the intended electronic application.

Gold Plating

Gold plating may be specified for certain electronic applications where particular surface contact or corrosion-resistance characteristics are required. Its suitability depends on the actual electrical interface, required coating thickness, substrate, and cost target.

Gold plating is not automatically necessary for every PCB shielding can. Customers should clarify whether the finish is required for electrical contact, soldering, corrosion resistance, or another specific purpose. The plating specification should identify the required thickness and applicable acceptance criteria.

EMI and RF Shielding Performance for PCB Assemblies

The primary function of a PCB shielding can is to help reduce electromagnetic interference affecting sensitive electronic circuits. It provides a conductive enclosure around selected components or circuit sections. However, the final shielding effectiveness depends on the complete shielding structure rather than the metal material alone.

Important factors include material conductivity, magnetic properties, thickness, enclosure geometry, opening size, seams, contact resistance, grounding arrangement, and the frequency range of interest. The PCB layout and the way the shielding can is installed can also influence the result.

Shielding Effectiveness in Decibels

Shielding effectiveness is commonly expressed in decibels (dB). A higher measured value generally indicates greater attenuation under the specified test conditions. However, a shielding value is meaningful only when the frequency range, test method, sample configuration, and measurement conditions are clearly identified.

For OEM projects, customers should provide their target shielding effectiveness and operating frequency range wherever possible. This information helps guide material selection and shielding structure discussions.

Grounding and Electrical Contact

The electrical connection between the shielding can and the PCB or shielding frame is an important design consideration. Poor contact, gaps, or inconsistent grounding may reduce the effectiveness of the complete shielding structure.

Mounting features, contact surfaces, soldering areas, and the surrounding PCB layout should therefore be considered during the design stage. For designs with strict EMC requirements, assembly-level validation may be necessary.

Material Testing and Finished-Part Testing

A material shielding report and a finished PCB shielding can test report do not provide exactly the same information. A material report describes the performance of the tested material under the laboratory's stated conditions. It does not automatically demonstrate the performance of a finished, formed shielding can installed on a PCB.

Finished-part performance may be affected by the enclosure geometry, forming operations, seams, openings, grounding, mounting contacts, and PCB assembly. Where performance requirements are strict, customers may need to test the finished component or complete electronic assembly.

Before arranging testing, customers should confirm whether the required evaluation is for flat material, a stamped shielding can, or the assembled PCB. The test method, frequency range, laboratory, and report requirements should be agreed in advance.

Dimensional Tolerances and Precision Inspection

PCB shielding cans are frequently used in compact electronic products where available installation space is limited. Accurate dimensions are therefore important for ensuring proper fit and avoiding interference with neighboring components.

For Sunny-1002, a tolerance of ±0.05 mm can be considered for critical dimensions, subject to part geometry, material thickness, tooling design, and process feasibility. The final tolerances should be identified on the approved engineering drawing.

Critical Dimensions

Typical critical dimensions may include overall length and width, enclosure height, wall position, cutout dimensions, mounting features, and the distance between locating points. For deep-drawn components, additional attention may be required for corner geometry and wall consistency.

First Article Inspection

First article inspection helps verify that the initial samples meet the agreed drawing requirements. Depending on the design, inspection may include overall dimensions, wall height, opening positions, forming geometry, material thickness, and surface condition.

Visual and Surface Inspection

Visual inspection can identify scratches, dents, cracks, deformation, plating defects, and other visible issues. Edge quality and burr direction should also be checked where they affect assembly, handling, or product safety.

Repeat Production Control

For recurring orders, stable tooling conditions, consistent material specifications, and controlled production processes are important. Customers may define inspection frequency, batch identification, and documentation requirements according to their internal quality standards.

Quality Management and Compliance Documentation

Electronic component manufacturers often require suppliers to provide quality-related documentation as part of their purchasing and supplier approval processes. The specific documents depend on the customer's industry, product requirements, and applicable regulations.

RoHS Requirements

RoHS requirements restrict certain hazardous substances in electrical and electronic equipment within the applicable regulatory framework. Customers may request material declarations, supplier documentation, or test reports to support their compliance assessment.

For Sunny-1002 projects, RoHS-related documentation should be confirmed according to the selected material, surface treatment, and actual product specification. A material declaration or report should not be assumed to cover every possible material and finishing combination.

ISO 9001 Quality Management

ISO 9001 is a quality management system standard rather than a product performance certification. Customers may request information about the manufacturing supplier's quality management system and applicable certification scope as part of supplier evaluation.

Where ISO 9001 documentation is required, its validity, issuing body, certificate holder, and scope should be verified before being presented as evidence of certification.

CE Marking Considerations

CE marking is relevant to products covered by applicable European Union harmonisation legislation. A standalone PCB shielding can is not automatically required to carry CE marking simply because it is used in electronic equipment.

Whether CE requirements apply depends on the finished product, its intended function, and the relevant legislation. Customers should evaluate CE obligations at the finished equipment level where applicable and confirm the appropriate compliance responsibilities.

Custom Tooling Development

Custom PCB shielding cans may require dedicated stamping or deep drawing dies. Tooling design should consider part geometry, material thickness, forming depth, critical dimensions, and expected production quantities.

For customers planning long-term orders, tooling investment can be evaluated in relation to expected annual demand and production efficiency. Tooling ownership, maintenance responsibilities, storage arrangements, and usage rights should be agreed as part of the project terms.

Prototype and Sample Production

Sample production allows customers to evaluate dimensions, appearance, assembly fit, and manufacturing feasibility before regular production. The appropriate sample method depends on design complexity, tooling requirements, material availability, and requested quantity.

For projects with specific EMI performance requirements, sample testing can be discussed separately. The test scope should identify whether the evaluation applies to the material, finished shielding can, or complete PCB assembly.

Applications of PCB Shielding Cans

PCB shielding cans are used across different electronic industries where electromagnetic interference control is an important part of product design. The required shielding structure depends on the electronic circuit, operating frequency, mechanical layout, and assembly method.
