Customized PCB Metal Shield Can for Device
What is Metal PCB Shield Can
A Metal PCB Shield is a type of shielding used in electronic devices to protect the circuit board from electromagnetic interference (EMI) and radio frequency interference (RFI). It is made from a thin sheet of metal, typically aluminum or copper, and is placed over the printed circuit board (PCB) to block any incoming or outgoing electromagnetic radiation.
These shields are essential in modern electronic devices where multiple components are packed closely together, and the risk of interference is high. The shields can also help to reduce crosstalk between different parts of the circuit, leading to better performance and reliability.
Metal PCB shields are available in various shapes and sizes, and they can be customized to fit specific PCB designs. They are often designed as a separate component that can be easily attached to the PCB, either by soldering or using clips or screws.
C7521 is the workhorse alloy for EMI Shielding can
When it comes to PCB EMI Shielding can , C7521& C7701 is the most popular EMI shielding can choice .Nickel silver c7521 &C7701 is a type of alloy that is primarily composed of nickel, copper, and zinc. for its excellent mechanical properties, such as high strength and corrosion resistance, making it suitable for various applications in different industriess. C7521& C7701 Nickel Silver advantages and characteristics include:
- Dimensional stability
- Good mechanical properties
- Corrosion-resistance
- Environmentally friendly (100% recyclability)
- Good tool life
- Low cost
- Excellent overall value
- No Rust
Tin plated for EMI Shielding can
When it comes to PCB EMI Shielding can , Tin plated (SPTE) is the most Cost optimization choice to make EMI shielding can , also known as tin plating iron, is commonly known as electroplated tin plate. The abbreviation is SPTE, which refers to a cold-rolled mild steel sheet or strip coated on both sides with pure tin. Tin is mainly used to prevent corrosion and rust.Tin plated advantages and characteristics include:
- Low cost
- Dimensional stability
- Good mechanical properties
- Environmentally friendly (100% recyclability)
- Good tool life
- Soldering Good
- Excellent overall value
Two Piece shield can
The two-piece is composed of a frame and a cover. The shield frame generally made of Nickel silver for easy soldering, and the cover is generally made of stainless steel, which is cheaper. The advantage of the two-piece type is that it is convenient for maintenance and inspection. The disadvantage is that the two pieces need to be opened twice, and the cost is high for the mould and the goods
One Piece Shield can+SMT Shield Clips
The shield clip is now used instead of the shield frame , which can save the cost of opening the shield frame . The shield clip is used to fasten the shield through the buckle, and it is enough to place one about 25mm, and at least 4 are required, which can be flexibly implemented. The disadvantage of this solution is that the clamping force of the buckle needs to be studied, and it is not suitable for use in scenarios with high vibration intensity

Reel and Tape Packing for EMI Shielding can
The carrier tape is mainly used in the electronic component mounting industry. It is used in conjunction with a cover tape (upper seal tape) to store the shielding cover in the pocket of the carrier tape, and forms a closed packaging by sealing the cover tape above the carrier tape to protect the shielding cover from contamination and damage during transportation. During the installation of the shielding cover, the cover strip is peeled off, and the automatic installation device accurately locates the shielding cover held in the pocket through the index hole of the carrier strip. The shielding cover is then removed in sequence and placed on the integrated circuit board (PCB) for installation advantages and characteristics include:
1. Corresponding to various forming methods, with good formability and dimensional accuracy.
2. Excellent thermal sealing with the upper sealing tape.
3. It has stable conductivity and protects the load from static electricity.
4. It has transparency that is easy to confirm with the naked eye.
Compared with previous PC series sheets, they have higher strength and can be ultra-thin.
6. The dust generated on the surface or edges of the carrier sheet is minimal and will not contaminate the load.
Tray packing for EMI Shielding can
When it comes to PCB EMI Shielding can packing, The basic function of Tray packaging is to protect the PCB shielding cover, especially during transportation, to avoid collision of goods. Customized lattice blister packaging can make product movement difficult and protect product integrity even during hard movements advantages and characteristics include:
- Low cost
- protect well
- Easy to use
- Lightweight quality
- Environmentally friendly (100% recyclability)
- Excellent overall value
