How to judge the quality of the reed

Beryllium copper reed is used in various occasions requiring EMI, RFI and ESD, and is widely used in communications, computers, mobile phones and military electronic equipment, it has high shielding performance, high thermal conductivity and is not affected by nuclear explosion, ultraviolet rays, ozone and other characteristics. It is formed in a variety of forms, and can be used for various shielded rooms/hatches/chassis doors/covers/printed boards/integrated circuit shields, etc. Now the quality of beryllium copper reeds on the market is good, uneven, we electronics are committed to the field of beryllium copper reeds to become industry experts, the courage to be the leader of the industry, integrity to do things, the use of imported materials, good elasticity, excellent quality, factory direct sales cost-effective.
How to distinguish the quality of beryllium copper reeds?
1. Look (raw materials, production process, corrosion resistance, salt spray test) raw materials if they are imported raw materials, the color is relatively bright, the surface is relatively smooth and textured In addition, the production process of beryllium copper reeds is: stamping - heat treatment - electroplating - cutting, etc., if there is oil on the surface of some products, etc. are not very high-quality products. Beryllium copper reed products whether natural color or electroplating products, will not be touched by the hand will have finger prints or black and yellow, if there is such a situation, most of the domestic products can be tested by salt spray to judge the quality of beryllium copper reeds, imported materials can at least be tested by 24H salt spray test without oxidation, and even some electroplating products are still bright after 96H
2. Pressure (test back elasticity, multiple presses still return to the original state) can be tested by resilience, keep pressing N times, measure the height of the product before and after, if the height is still not low or the rebound is intact after pressing thousands of times, it can prove that the raw material of beryllium copper reed is better and the heat treatment process is relatively perfect
