0.25mm Full Hard Phosphor Bronze CR3034 SMT Contact

Huizhou Antenk Electronics Co., Ltd. manufactures BS-M-SI-R-CR3034A SMT battery contact compatible with CR3034 CR2032 CR2025 DL2020 and BR2016 coin batteries to deliver reliable elastic conductive connection between coin batteries and PCB mounting pads. This metal contact is crafted from 0.25mm thick full hard phosphor bronze raw material with standard 30 to 50 micro inch nickel plating, and buyers can choose multiple gold plating grades from gold flash up to 30 micro inch gold to boost anti oxidation and long term conductive stability. It adopts SMT surface mount structure that complies with ANSI EIA 481 tape and reel standards, supporting bulk bag packing and tape reel packing with 500 pieces per reel to fit manual assembly and automated high speed SMT production lines. This battery contact is widely used in digital cameras communication equipment industrial control sensors smart home appliances electronic toys and precision measuring instruments. Operators must follow official PCB mounting pad layout during reflow soldering, avoid over bending to prevent permanent phosphor bronze spring fatigue deformation and store finished contacts in dry warehouse to avoid nickel plating corrosion. Unlike suppliers that outsource stamping and electroplating processes Antenk carries out full in house production workflow covering independent precision mold development full hard phosphor bronze high speed stamping nickel gold electroplating and strict laboratory dimensional and reliability testing, holding ISO9001 ISO14001 IATF16949 and UL E472792 certifications and fully meeting RoHS HSF and REACH environmental standards. We own abundant self developed metal terminal molds, offer customizable plating and packaging solutions, provide round the clock professional technical support, and more than seventy percent of our battery contacts are exported worldwide backed by our Guangdong Famous Trademark ANTENK and consistent stable batch manufacturing quality.
