Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001 and ISO14001 certified manufacturer founded in 2004 with over 250 employees and a 10,000m² facility, proudly presents the THREE AA BATTERY HOLDER SMT TYPE. This surface‑mount battery holder is specifically engineered to hold three standard AA (LR6) batteries in series, providing a nominal 4.5V output. Unlike traditional through‑hole holders that require manual soldering and board drilling, the SMT design features flat, solderable metal pads on the underside of a high‑temperature LCP (Liquid Crystal Polymer) housing, enabling fully automated pick‑and‑place and reflow soldering. Manufactured using our 8 Japanese/Taiwanese injection molding machines with LCP (UL94V‑0 rated, heat deflection temperature 280°C), and stamped nickel‑plated phosphor bronze contacts on 11 precision presses, this holder delivers a contact resistance below 30 milliohms per cell and a collective current rating of 5A. Key characteristics include a low profile of only 6.5mm above PCB, independent spring‑loaded negative contacts for each battery ensuring consistent force (100–150g per cell), an integrated polarity key to prevent reverse insertion, and operating temperature range -40°C to +105°C. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated optical inspection.
Application Scope: This SMT AA battery holder is ideal for high‑volume portable electronics requiring 4.5V power, including medical devices (infusion pumps, patient monitors), industrial wireless sensors, IoT gateways, portable gas detectors, remote controls, children's toys, and backup memory modules – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: The holder is supplied on tape‑and‑reel (250pcs/reel) for automatic placement. Solder the six SMT pads (two per battery position) using standard reflow soldering (peak 260°C, recommended stencil thickness 0.15mm). The LCP housing withstands reflow without deformation. After soldering, insert three AA batteries positive (+) to negative (-) in series as indicated by polarity markings on the housing. The negative spring contacts will compress, and the batteries will snap into place. To remove, slide a non‑conductive tool under each battery edge to release spring tension. Precautions: Do not exceed 5A total current; ensure correct polarity before insertion; do not reflow solder more than twice; avoid using damaged or leaking batteries; operate within -40°C to +105°C range. Advantages Over Competitors: Unlike competitors who offer only through‑hole AA holders (requiring manual soldering and board drilling, adding 30–50% assembly cost), Antenk’s SMT version reduces assembly time by 70% and eliminates drilling costs. Competitors often use PBT or nylon that warps during reflow; Antenk uses LCP (Liquid Crystal Polymer) with 280°C HDT, ensuring flatness after soldering. While others require 15,000+ MOQ for SMT tooling, Antenk offers low MOQs (1,000 units) with no tooling fees for standard 3‑cell spacing. Our IATF16949 certification ensures automotive‑grade quality. Additionally, our 48‑hour salt spray testing and 10,000‑cycle battery insertion validation guarantee reliable contact even in high‑vibration environments. The SMT design also allows double‑sided PCB assembly, saving board space.
Antenk’s vertical integration delivers consistent quality for the Three AA SMT holder. Process flow: (1) In‑house mold design using our 250+ plastic injection molds (dedicated 3‑cell LCP mold with precision cavities); (2) Injection molding on 8 Japanese/Taiwanese machines using LCP resin – molded at 330°C with 120°C mold temperature to achieve flatness <0.1mm; (3) High‑speed stamping of six contact terminals (three positive nubs, three negative springs) on 11 presses using 0.25mm phosphor bronze; (4) Barrel plating: nickel (3μm) + optional selective tin on solder pads; (5) Automated assembly: terminal insertion into LCP housing with ultrasonic stake for permanent retention; (6) 100% coplanarity test (all SMT pads within 0.1mm); (7) Contact resistance testing per EIA-364-06 for each cell position; (8) Spring force testing per EIA-364-04 (100–150g per cell); (9) Reflow simulation test (260°C, 3 passes) to verify no warpage; (10) 48‑hour salt spray testing; (11) Final QC with lot traceability and dimensional report. Our laboratory houses 20+ testing devices including profile projectors, environmental chambers, and 3D optical profilers. With 250+ employees, 18+ mold‑making machines, and 180+ automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings with recommended PCB footprint, and 24‑hour technical support.
