How Choose the
Type for PCB EMI Shield Can
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
Deep Drawn shield can
Deep drawn shield can technology has been developed. This technology uses a deep drawn process to form the shield, which eliminates the gaps between the shield body and the vertical edge, and between the vertical edge and the vertical edge. This greatly reduces the interference to the radio frequency, and improves the overall performance of the shield.
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
