PCB Shield Can - Custom Precision EMI Shield Cans for Electronic PCB Boards

Product Overview

PCB Shield Can is a special electromagnetic interference (EMI) shielding component specially designed for electronic printed circuit boards (PCBs), which is a core accessory to ensure the stable operation of precision circuit modules. This type of shielding can is most widely used in mobile phone PCBs, and is also gradually popularized in various communication electronic equipment and consumer electronic PCBs, mainly used to solve the problem of signal interference between different circuit modules. We have rich professional experience in the R&D, mold development and mass production of PCB special shielding cans, and have a thorough grasp of the structural design, performance requirements and assembly standards of such products, providing pure OEM customized services for global electronic customers.

Our PCB shielding cans adopt high-precision progressive stamping process for mass production, with strict control over product flatness and welding performance, and support a variety of conventional shielding materials to meet different cost and performance needs. We have a stable monthly delivery capacity of 1.5 million pieces, which can fully meet the large-scale batch supporting needs of PCB assembly manufacturers and electronic product brands. Relying on mature stamping technology and strict quality control, we ensure that each shielding can meets the SMT welding and circuit shielding requirements of PCBs, and provide customers with flexible packaging options to adapt to automated production and conventional storage needs.

Core Product Functions

PCB Shield Can has two irreplaceable core functions in PCB circuit applications, namely electromagnetic interference isolation and physical anti-collision protection, which jointly ensure the normal operation and safe production of electronic products. The primary and most critical function is electromagnetic signal isolation, which is especially indispensable for mobile phone PCBs equipped with GPS, BT, Wifi, 2G/3G/4G/5G and other multi-band wireless communication circuits. It can effectively isolate sensitive analog circuits and DC-DC switching power supply circuits, prevent high-frequency signal interference between different circuit modules, avoid mutual influence between communication circuits and conventional circuits, and ensure the stability and clarity of signal transmission and power supply output.

The second core function is physical anti-collision and separation protection. After the PCB completes the SMT patch process, it needs to be cut and divided into multiple single boards; the PCB shielding can plays a separation role between adjacent single boards, preventing the boards from being too close to each other, and avoiding collision damage between circuit modules or components during subsequent testing, transportation and assembly processes. In addition, the shielding can also provides a certain physical protection for the internal circuit components, preventing dust adhesion and external extrusion from damaging the precision components on the PCB.

Key Product & Production Features

Our PCB Shield Can has targeted performance and process advantages tailored to PCB assembly requirements, with excellent welding performance, high flatness and structural adaptability as core highlights, fully meeting the standards of automated SMT production. In terms of material selection, we provide a variety of high-quality optional materials, including nickel silver, stainless steel, tinplate, etc., and currently most of the customized products use nickel silver as the main material, because this material has excellent tin soldering performance, matching the SMT welding process of PCBs, ensuring firm and stable welding without false soldering or falling off.

We have strict precision control for the bottom flatness of the shielding can, which is guaranteed to be within 0.05mm, a key indicator to ensure the tight fit between the shielding can and the PCB surface, avoiding gaps caused by unevenness and affecting shielding effect and welding firmness. All products adopt high-precision progressive stamping process, with smooth surface without burrs and deformation, no additional post-treatment required, which reduces production costs and shortens delivery cycles. In terms of structural design, we follow the industry's two conventional structural forms, which can be customized according to customer needs, and fully adapt to different PCB assembly and later maintenance scenarios.

Structural Classification & Application Differences

PCB Shield Can is divided into two mainstream structural types according to usage scenarios and maintenance needs, namely one-piece integrated structure and two-piece split structure, each with its own applicable scenarios. The one-piece shielding can has a simple integrated structure, lower production cost, and can be directly mounted and welded to the PCB through SMT process, which is suitable for mass-produced electronic products that do not require frequent later circuit debugging and have strict cost control. The two-piece split shielding can is composed of a fixed frame and a detachable cover; the frame is welded to the PCB, and the cover can be freely disassembled and assembled, which is convenient for later hardware debugging, signal testing and maintenance, suitable for products requiring high flexibility in later maintenance.

Product Specifications & Production Capacity

This PCB Shield Can is a purely OEM customized product, with no fixed unified standard specifications, and all parameters including shape, size, height, opening position and structural form are completely designed and produced according to customer-provided PCB drawings or physical samples. The optional materials include high-quality nickel silver, cost-effective tinplate, wear-resistant stainless steel and other electronic special shielding materials, customers can match the material according to product performance, welding needs and budget. The core production process is high-efficiency precision progressive stamping, with mature and stable process, and no additional surface post-treatment is configured by default.

Conventional performance testing is not provided for this product by default, and targeted shielding performance or flatness testing can be arranged separately according to customer special needs. We provide two practical packaging methods: carrier tape packaging suitable for automated SMT patch production, and conventional PE bag packaging for manual assembly and conventional storage. This product is dedicated to the electronic manufacturing industry, with a stable monthly delivery capacity of 1.5 million pieces, which can meet the long-term large-scale supporting procurement needs of PCB factories and electronic product manufacturers, and ensure on-time delivery and consistent batch quality.

Application Scenarios

PCB Shield Can is mainly used in electronic equipment with complex circuit modules and high signal stability requirements, and its core application scenario is mobile phone PCBs, adapting to various smart phones equipped with multi-band wireless communication modules. In addition, it is also widely used in other consumer electronic equipment PCBs, communication terminal equipment, network equipment, small household appliance control circuit boards, automotive electronic PCBs and other products, especially suitable for circuit boards integrating wireless communication circuits, sensitive analog circuits and DC-DC switching power supply circuits. It is also suitable for PCB products that need to be cut and separated after SMT, effectively preventing collision damage in the subsequent process.
