TOP > Products > Metals for Communications, Semiconductors and Packages > Clad metals for package sealing (Ag-Cu alloy/KV, etc.) Metals for Communications, Semiconductors and Packages ●Clad metals for package sealing (Ag-Cu alloy/KV, etc.) 【Features】 Various communication devices are used in personal electronic equipment, including mobile equipment such as smartphones and tablet terminals. We have developed a number of package sealing clad metals and hermetic sealing and bonding processes suitable for production of these devices. Our seal rings and lids, pre-clad with brazing materials for sealing, are widely used for their abilities to make such devices smaller and lower. We offer products which suit the required applications through combining those materials with thermal expansion properties which agree in a wide temperature range with that of ceramic packages and other materials, such as those having low proof stress. We are also able to carry out one-by-one processing of these clad metals, realizing reduction of particle and gas emissions through use of clean-rooms. 【Product image】 Material samples: seal rings and lids for ceramic packages [Ni/KV/Ni, Ag-Cu alloy/KV] 【Applications】 Seal rings and lids for ceramic packages 【Materials】 Seal rings: BK Lids: NKN-B72, NKC-72, NKN-SAG 【Technology】 ・Punching/Drawing press ・Plating (electrolytic/electroless plating) ・Laser trimming ・Brazing ・Product evaluation/Analysis 【Usage example】 We can also provide cavity type lids. 【技術資料・カタログ】 ・クラッド（PDF形式、clad.pdf、7,073KB） --> Products Metals for Environment and Energy Clad metals for batteries Metals for batteries Clad metals for heat exchangers Metals for Automobiles Clad metals for rechargeable batteries Clad metals for batteries Clad metals for heat spreaders Materials for resistors Bimetals Temperature compensator alloys Permalloys Copper phosphorus brazing filler metal/Copper clad Copper-clad stainless steel Joining materials Metals for Communications, Semiconductors and Packages Iron-Nickel-Cobalt alloys Iron-Nickel alloys Low thermal expansion alloys for precision equipment Permalloys Clad metals for heat spreaders Metals for laser diodes Clad metals for smartphones Bimetals Metal parts for package sealing Au coated Ni-P particles Lead pins Metals for functional parts Copper alloy strip for semiconductor lead frames Dual gauge copper strip Plated copper strip and dual gauge copper strip Copper strip for heat sinks and heat spreaders Copper strip for ceramic substrates General industry Copper bar, copper rod, formed bars, hollow conductors Fabricated products Copper strip for industrial applications Oxygen-free copper rods containing zirconium Oxygen-free copper Class 1 Metals for Domestic Electrical Applications Lead frame materials for LEDs Iron/Copper clad Clad metals for button-type batteries Bimetals Temperature-sensitive magnetic materials Permalloys Clad metals for conductive springs Temperature compensator alloys Metals for information technology devices Stainless steels for heater applications Metals for Special Applications Corrosion-resistant alloys/Heat-resistant alloys Low thermal expansion alloys Alloys for high tensile strength springs Material technologies Material technologies Material technologies Extremely thin metallic foils (High-precision rolled foils) Processing technology Forming modified cross-section shape Machining Bending Welding Punching Drawing press Heading Metal ball manufacturing process Brazing Magnetic annealing Surface treatment technologies Plating(Fine processed products、Strip) Plating on hoops and extremely thin metallic foils Corporate Profile Message from the President --> Corporate Summary and History Major Offices and Access Map Proterial Group Codes of Conduct CSR Activities of Proterial Group Companies Environmental Activities Quality Management Cautions Regarding Product Use Contact Us PAGE TOP Corporate Profile Message from the President > --> Corporate Summary and History > Major Offices and Access Map > Proterial Group Codes of Conduct > CSR Activities of Proterial Group Companies > Environmental Activities > Quality Management > Cautions Regarding Product Use > Contact Us > About Personal Information Protection | Sitemap | Proterial Metals Website Terms of Use COPYRIGHT ©Proterial Metals, Ltd.
