⚠️ Critical NPI Compliance Directive
SMT reflow failures and pad misalignments frequently originate from unverified 3D models. To ensure automated assembly yield, our protocols strictly prohibit the online distribution of digital CAD files. Validate your SMT land patterns accurately by submitting your board constraints to our NPI Engineering Queue. We will dispatch dimensionally controlled 2D Footprint Specs and matched PDF layouts within 12 working hours.
Longitudinal Tolerance & 1:1 Pad Matching
Managing dimensional variations across multiple cylindrical cell formats (AAA, AAAA, N, A23, A27) demands components with superior compression recovery. The JIATEL JT-BC-AAA-1076N is a direct SMT footprint replacement for the Keystone 1076N, designed specifically to absorb longitudinal cell tolerance while maintaining unbroken electrical continuity.
- ✅ Target Alternative: 1:1 footprint match for Keystone 1076N
- ✅ SMT Geometry: 6.35 mm x 5.08 mm base pad
- ✅ Structural Design: 90° bent angle for vertical cell alignment
- ✅ Board Adhesion: 3.43 mm x 1.57 mm solder wicking slot
Spring Fatigue Extremes & Metallurgy
To prevent cathode tension loss after repeated battery insertion cycles, we engineer the negative terminal using a helical spring wound from Ø0.50 mm music wire. This component exhibits extreme resistance to metal fatigue.
- ⚙️ Base Architecture: Rigid T=0.30 mm Stainless Steel
- ⚙️ Tension Element: Ø0.50 mm Music Wire Spring
- ⚙️ Thermal Profile: Optimized for automated lead-free reflow
- ⚙️ Surface Finish: Full Nickel Plating for superior solder paste wettability and oxidation resistance
