Engineering Datasheet: SMT Battery Clip, Direct Footprint Replacement for Keystone 55
Securing cylindrical cells on FR4 boards requires flat SMT pads. The Jiatel JT-BCK-AA-KS55 is a direct footprint replacement for Keystone 55. This SMT clip allows hardware engineers to execute seamless board-level integration. You do not need to alter existing PCB pad layouts. You can also keep your current reflow solder stencil designs.

Metallurgical Rigidity & Solder Joint Integrity
We stamp the JT-BCK-AA-KS55 from rigid T=0.30mm Spring Steel. This precise metal thickness provides absolute structural rigidity. The U-channel clamping arms will not yield under constant pressure. We finish the entire assembly with high-density Nickel Plating. This plating maximizes solder paste wettability during the reflow process. It eliminates the risk of cold solder joints on SMT lines.
NPI PCB Footprint Audit & SLA Directive
Board-level assembly demands strict adherence to pad dimensions and axial spacing. Layout errors cause reflow misalignment and battery seating failures. Our engineering rules strictly prohibit using unverified 3D models. We execute footprint validation exclusively through official [Technical Datasheets]. We also rely on dimensionally controlled [2D Footprint Specs].
