Metal terminals , E M I /R F shield , metal contacts and Various kinds of C N C parts are widely used in computer equipment, communication products, consumer electronics, automotive, medical electronics, instrumentation and aerospace equipment. Products are exported to Europe, the United States, the European Union, South Korea, Japan, Taiwan and Southeast Asia and so on. Bosi is guided by the business philosophy of "speed and passion, quality first", We are increasingly aware of the pain point and the demand of the non-standard industry, the timeliness of leadtime and low cost of the samples. Bosi has introduced the advanced miniature controllable precision bending machine from Germany, Micro bender can handle material thickness between 0.04 and 1.0 mm,maximum bending width of 150 mm, minimum bend width of 2.0 mm, precision up to 0.01 mm and angle up to 0.1 °，We can achieve one day for samples and saving openning mold,the flatness up to 0.02mm, accuracy up to 0.01mm. We pay attention to team management, treat quality as enterprise life, and Set up quality guarantee system, we past the certificate of quality system of I S O 9 0 0 1:2 0 1 5 and I A T F 1 6 9 4 9:2016. We sincerely look forward to cooperating with you!
bbin体育Contact strips are used to close and shield gaps between two surfaces. For optimum shielding performance, the contact strip should be able to close the minimal and maximal gap.
Material properties of contact springs
Contact strips are made of beryllium copper, a material that offers excellent spring characteristics in combination with a high material strength. Further advantages are corrosion resistance and self cleaning of contacts by opening and closing.
Beryllium copper is resistant against air, ozone, solvent, UV light and even against nuclear radiation. It can be used over a wide temperature range and shows excellent thermal and electric conductivity. In comparison to other EMI/RFI gaskets, contact strips are lighter and require less closing force. They are also inflammable and free from outgassing.
Different contact springs
Available in a variety of surfaces
The wide profile range in combination with several mounting methods creates an universal shielding gasket. The easiest mounting methods are clip-on and the type using a double sided pressures sensitive adhesive tape.
Soldering or spot welding ensure very good grounding and contact. Generally the electrochemical reaction should be considered to avoid galvanic corrosion. In many cases it is recommended to use special surface treatment (i.e. tin plating) to get closer in the electrochemical potential chart.
As standard contact strips are supplied in bright clean surface (copper). On request a surface finish like tin plating, zinc plating, nickel plating, silver plating, gold plating etc. can be applied.
When using the correct compression force the contacts will not be damaged and thereby maintain their spring characteristic.
