Q&A for the board level shielding can use Tin plated material - Ningbo Hexin Electronics Co.,Ltd.

Q: Will tinplate be used as an electronic shield material to rust at its shortcomings? How to solve if rust? Can there be better materials?

Answer: Tinplate can be used as an electronic shielding cover. It is a kind of many kinds of materials. It is cheap and has good processing performance. However, it is relatively easy to rust among all shielding materials, which affects the welding performance. This is also its The only flaw. If short-term prevention is still possible. After all, it takes time to rust! Electroplating is not the best way to solve the problem. My supplier will apply a layer of anti-rust material to the weld and do another ultrasonic cleaning before delivery. However, it is better to use nickel silver. Although it is a little more expensive than tinplate, its performance is much better than tinplate. Generally, we also recommend “foreign nickel silver” first.

Question: Is tinplate suitable for electronic shielding? What other materials can be used?

Answer: The most commonly used materials for electronic shields are nickel silver and tinplate. Both materials have very good welding performance and the surface is tin-plated! But the above mentioned that the tinplate fracture is easy to rust, but the mobile phone must pass the salt spray test, so it is better to use nickel silver. The electronic shield is also made of stainless steel. Due to its poor solderability, it can only be used on a small number of accessories or components that do not require soldering!
