Product details

Huizhou Antenk Electronics Co., Ltd. produces BS-M-SI-A-CR2032A SMT battery contact designed to deliver stable elastic conductive connection for CR2025 and CR2032 coin batteries on PCB circuit boards. This metal contact is manufactured from 0.25mm thick phosphor bronze with standard 4 micro inch uniform nickel plating, and customers can pick multiple alternative plating finishes ranging from gold flash to 30 micro inch gold to strengthen anti-corrosion performance and consistent electrical conductivity. It is an SMT surface mount style with standardized PCB matching dimensions, supporting tray packing and tape reel packing two packaging options to fit manual assembly and high-speed automatic SMT mass production lines. This battery contact operates reliably within the temperature range of minus 40 degrees Celsius to 270 degrees Celsius and withstands 270V voltage, widely adopted in digital cameras communication devices industrial control modules smart home appliances electronic toys and precision measuring instruments. Operators must follow official PCB dimension specifications during reflow soldering, avoid excessive bending force to prevent irreversible phosphor bronze spring deformation and store finished contacts in dry storage space to protect nickel coating from oxidation. Unlike competitors that outsource stamping and electroplating processing Antenk realizes full independent production workflow including self-developed mold design phosphor bronze high-speed stamping nickel gold electroplating and complete laboratory electrical performance testing, holding ISO9001 ISO14001 IATF16949 and UL E472792 certifications and fully complying with RoHS HSF and REACH environmental standards. We own hundreds of self-developed precision metal terminal molds, supply customized plating and packaging solutions, offer 24-hour professional technical support, and over seventy percent of our battery contacts are exported worldwide supported by our Guangdong Famous Trademark ANTENK and stable uniform batch production quality.

0.25mm Thin Phosphor Bronze Tab serves as the core elastic conductive part of this SMT battery contact and maintains steady clamping force for CR2025 and CR2032 coin cells.

4um Uniform Nickel Coated Tab forms a complete anti-rust barrier on the phosphor bronze substrate to reduce contact resistance and extend product service life.

Wide Temp SMT Coin Cell Spring keeps stable elastic and conductive performance under operating temperature from -40℃ to 270℃ for diverse electronic equipment.
