Engineering Datasheet: SMT Coin Cell Retainer, Direct Footprint Replacement for Keystone 2998
Securing micro coin cells on high-density FR4 boards requires precise SMT pads. The Jiatel JT-BC-KS2998 is a direct footprint replacement for Keystone 2998. This micro retainer allows hardware engineers to execute seamless board-level integration. You do not need to alter existing PCB pad layouts. You can keep your current reflow solder stencil designs.

Metallurgical Rigidity & Solder Joint Integrity
We stamp the JT-BC-KS2998 from rigid T=0.25mm Phosphor Bronze. This specific material provides excellent fatigue resistance. The top clamping arms will not yield under constant battery pressure. We finish the entire assembly with high-density Nickel Plating. This plating maximizes solder paste wettability during the SMT reflow process. It eliminates the risk of cold solder joints.
NPI PCB Footprint Audit & SLA Directive
Board-level assembly demands strict adherence to pad dimensions. Layout errors cause reflow misalignment and battery seating failures. Our engineering rules strictly prohibit using unverified digital mockups. We execute footprint validation exclusively through official [Technical Datasheets]. We also rely on dimensionally controlled [2D Footprint Specs].
Please confirm that our SMT retainer matches your land pattern needs. Engage our Senior NPI Engineering Team for layout verification. Submit your board constraints directly to our technical desk: NPI Engineering Queue. We will dispatch matched, production-ready PDF drawings within 12 working hours.
