Engineering Datasheet: SMT Coin Cell Retainer, Direct Footprint Replacement for Keystone 3034
Securing standard Ø20.0mm coin cells on high-density FR4 boards requires precise SMT pad layout matching. The JIATEL JT-BC-2032-KS3034 is a direct footprint replacement for the Keystone 3034. This compact retainer allows hardware engineers to execute seamless board-level integration for CR2032 and CR2025 backup cells. You do not need to alter existing PCB pad coordinates or reflow solder stencil designs.

Metallurgical Rigidity & Solder Joint Integrity
We stamp the JT-BC-2032-KS3034 from rigid T=0.25mm Phosphor Bronze. This specific material formulation provides excellent spring fatigue resistance for 20.0mm cells. The top clamping arms will not yield under constant battery insertion pressure or operational vibration. We finish the entire assembly with high-density Nickel Plating. This maximizes solder paste wettability across the 22.90mm base span during SMT reflow. It eliminates the risk of cold solder joints and physical detachment.
NPI PCB Footprint Audit & SLA Directive
Board-level assembly demands strict adherence to pad dimensions and coplanarity limits. Layout errors cause reflow misalignment and battery seating failures. Our engineering rules strictly prohibit the distribution of unverified digital mockups. We execute structural footprint validation exclusively through official [Technical Datasheets]. We rely on dimensionally controlled [2D Footprint Specs].
Confirm that our SMT retainer matches your land pattern constraints. We must deploy our Senior NPI Engineering Team to ensure a 1:1 footprint replacement. Submit your parameters directly to our technical desk: NPI Engineering Queue. We will dispatch matched, production-ready PDF drawings within 12 working hours.
