Engineering Datasheet: SMT Battery Clip, Direct Footprint Replacement for Keystone 53
Securing cylindrical cells on high-density FR4 boards against lateral mechanical shock demands extreme retention force and absolute SMT pad coplanarity. The Jiatel JT-BC-AA-KS53 functions as a high-reliability, 1:1 direct footprint replacement for the industry-standard Keystone 53 battery clip. Engineered specifically for automated pick-and-place assembly, its U-channel gripping arms allow hardware engineers to execute seamless board-level power integration without altering existing PCB pad layouts or reflow solder stencil designs.

Metallurgical Rigidity & Solder Joint Integrity
To prevent cell dislodgement during drop tests and ensure zero-defect reflow soldering, the JT-BC-AA-KS53 is precision-stamped from a heavier T=0.35mm Spring Steel. This specific metallurgical gauge guarantees absolute structural rigidity for the lateral clamping arms, preventing the clip from yielding under repeated battery insertion cycles. The entire assembly is finished with high-density Nickel Plating, maximizing solder paste wettability across the 16.80mm base footprint and eliminating the risk of pseudo-soldering (cold joints) on the SMT line.
NPI PCB Footprint Audit & SLA Directive
Board-level integration demands strict adherence to pad dimensions (16.80mm MIN length) and component spacing (L-dimension) to prevent SMT reflow misalignment and battery seating failures. Our engineering directive strictly prohibits the deployment of unverified 3D STEP models or direct 3D CAD files for PCB layout confirmation. We execute structural footprint validation exclusively through official [Technical Datasheets] and dimensionally controlled [2D Footprint Specs].
