Beryllium copper shrapnel

Beryllium copper shrapnel is made of beryllium copper alloy shrapnel with electromagnetic compatibility shielding effect, which can be used to seal the gap between two contact surfaces and provide high shielding effect. The shrapnel can also be selected from stainless steel and phosphorus bronze according to customer needs. Beryllium copper shrapnel has high relaxation resistance and excellent wear resistance, and can be subjected to multiple metal electroplating treatments to ensure compatibility with any contact surface. It not only does not burn, but also is not affected by radiation. Based on these advantages, design engineers in computer and electrical production consider beryllium copper shrapnel as an ideal electromagnetic compatibility shielding material. Beryllium copper shrapnel can be used in electronic devices with a wide range of EMI/RFI or ESD applications. Used for various shielding rooms/covers/printed board inserts/integrated circuit shielding, etc. Beryllium copper shrapnel can work well in various environments and can choose multiple coatings to ensure electrochemical compatibility with other contact surfaces. It will not burn and will not be affected by radiation or ultraviolet rays. Due to these reasons, excellent designers use beryllium copper shrapnel for EMI shielding in computing centers, 5G base stations, and other electronic devices. Konlida uses beryllium copper material: Beryllium copper material imported from Brushwellman in the United States, which belongs to high beryllium materials (containing 1.8-2.0% beryllium); There are two types of materials before heat treatment: C17200-1/4H and C17200-1/2H, corresponding to the hardness of the original material: 110-180HV and 175-230HV. There are mainly two types of stamping material options available. After heat treatment, the minimum hardness is higher than 373HV. Summary: Choosing 1/4H and 1/2H is invalid for end customers. Non conductive double-sided acrylic pressure-sensitive adhesive, model 3M 9469PC or equivalent, with a thickness of 0.13mm and clear color. Temperature range -40 ° C to 121 ° C. The shelf life is 12 months. Apply to clean and dry surfaces at room temperature. Use external alcohol to remove all oily residues. After the gasket is in place, press firmly to achieve good bonding. Repositioning the gasket may weaken the effectiveness of the adhesive or damage the adhesive strip. Reaching 50% of ultimate strength after 20 minutes, 90% after 24 hours, and 100% after 72 hours. The rising temperature may increase the ultimate bonding strength faster. 3M tape is moisture resistant, solvent resistant, and high-temperature resistant, and meets MIL standard specifications. Installation method for metal beryllium copper shrapnel: 1. Slotting installation: Cut out the holes and slots required to install the product on the panel. The length of the hole groove depends on the length of the product. Taking our MB-1116-01 as an example: panel thickness: T=1.0MM; The hole spacing is approximately 6.6mm; MB-1721-01 corresponds to a panel thickness of T=1.50MM; Other: MB-1216-01, MB-1136-01, MB-1711-01, etc. can also use similar installation methods; 2. Adhesive tape: This method is very effective and requires a certain amount of pressure. It is an ideal choice for metal casing and electronic casing shielding strips; Most commonly used: MB-1550-01/1551-01; MB-1500/520/521/540/541-01, etc; Our company mainly uses 3M’s 9469 tape, conductive tape such as 3M9703. 3. Other installation methods: such as riveting, brazing, clamping, etc; 4. Rivet fixed type; 5. Welding method; 6. Brazing method; The application of beryllium copper has a wide range of applications, such as shielded rooms, cabin doors, chassis doors, cover plates, printed board inserts, and integrated circuit shields. The advantages of beryllium copper shrapnel include low pressure, high-strength high-strength copper alloy lifespan, highest spring performance, excellent conductivity, compliance with large gap changes, dimensional stability, and excellent bi-directional application. It has large temperature changes and is non-magnetic. It is resistant to stress relaxation, easy to install, non flammable, easy to electroplate, multiple installation options, sizes, and configurations. It complies with RoHS
