Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001:2015 and ISO14001:2015 certified high‑tech enterprise founded in 2007 with over 300 employees and a 10,000m² Huizhou facility, proudly presents the SINGLE 1/2 AA BATTERY HOLDER SMT. This surface‑mount holder is precision‑engineered for 1/2 AA lithium or alkaline cells (14mm diameter × 25mm length) – a compact power source widely used in long‑life industrial sensors, medical implants, and IoT end nodes. Unlike traditional through‑hole holders, the SMT version features flat, solderable nickel‑plated pads on the underside of a high‑temperature LCP (Liquid Crystal Polymer) housing (UL94‑V0, heat deflection temperature 280°C), enabling fully automated pick‑and‑place and reflow soldering. The positive contact is a dual‑beam stamped beryllium copper spring, while the negative contact uses a captive coil spring – both finished with selective gold plating (0.4μm) for ultra‑low resistance. Key characteristics include a contact resistance below 20 milliohms, retention force of 130–170g, continuous current rating of 2.5A, an operating temperature range of -40°C to +125°C, and an ultra‑low profile of just 6.2mm above PCB. The integrated polarity key prevents reverse insertion. The product is RoHS, REACH compliant and UL recognized (E472792).
Application Scope: The 1/2 AA SMT holder is ideal for high‑volume, automated assembly of compact devices such as wireless industrial sensors, active RFID tags, portable medical monitors (glucose meters, insulin pumps), GPS tracking modules, utility meters, memory backup circuits, and wearable electronics – markets where Antenk already serves customers including Flextronics, Foxconn, and Fortune 500 companies across the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: The holder is supplied on tape‑and‑reel (500pcs/reel) for automatic placement. Solder the two large SMT pads using standard reflow soldering (peak 260°C, recommended stencil thickness 0.15mm). The LCP housing withstands reflow without warpage. After soldering, manually insert the 1/2 AA battery with positive (+) end against the dual‑beam contact and negative end against the coil spring – an audible click confirms full seating. The housing’s polarity key ensures correct orientation. To remove, use a plastic pry tool under the battery edge. Precautions: Do not exceed 2.5A continuous current; avoid reflow soldering more than twice; do not use with batteries longer than 26mm; operate within -40°C to +125°C. Advantages Over Competitors: Unlike competitors who offer only THM 1/2 AA holders (requiring board drilling and manual soldering, adding 30–50% assembly cost), Antenk’s SMT version eliminates drilling and reduces placement time by 80% – ideal for high‑volume production. Competitors often use PBT that warps during reflow; Antenk uses LCP with 280°C HDT and <0.05mm coplanarity after reflow. While others require 15,000+ MOQ for SMT tooling, Antenk offers low MOQs (1,000 units) with no tooling fees for standard configurations. Our IATF16949 certification ensures automotive‑grade reliability, and our in‑house 40+ lab test devices (including XRF, environmental chambers, and 3D profilers) guarantee every batch meets EIA‑364 standards.
Antenk’s vertical integration delivers consistent quality for the 1/2 AA SMT holder. Process flow: (1) In‑house mold design using our 380+ plastic injection molds (dedicated 1/2 AA SMT cavity with ±0.02mm tolerance on battery cavity and pad flatness); (2) Injection molding on 10 Japanese/Taiwanese 35‑120 ton machines using LCP resin (melt 330°C, mold 120°C, cycle time 14 seconds) – the material is pre‑dried to prevent voids; (3) High‑speed stamping of positive dual‑beam (beryllium copper) and negative spring contacts on 9 Japanese/Taiwanese presses using 0.20mm strip; (4) Selective gold plating: nickel underplate (2μm) + gold (0.4μm) on contact tips only; (5) Automated spring coiling on Japanese CNC coilers (±0.05mm pitch control); (6) Semi‑automatic assembly: insert contacts into LCP housing, ultrasonic stake for permanent retention; (7) 100% coplanarity inspection (all SMT pads within 0.08mm) using laser profilometer; (8) Spring force testing per EIA-364-04 (130–170g); (9) Contact resistance testing per EIA-364-06 (<20 milliohms); (10) Reflow simulation test (260°C, 3 passes) to verify no warpage or solder wicking; (11) 48‑hour salt spray corrosion testing; (12) Tape‑and‑reel packaging (500pcs/reel) with 100% visual and electrical verification. Our laboratory houses 40+ testing devices including XRF, environmental chambers, and automated spring testers. With 300+ employees, 18+ mold‑making machines, and 180+ automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings with recommended PCB land pattern, and 24‑hour technical support. Contact Antenk today – we respond within 4 hours and ship 1/2 AA SMT holder samples within 3 days. Ask about volume discounts (5,000+ units) and custom options (gold thickness, different retention forces, or high‑temp LCP for lead‑free reflow). With 70% of our products exported to 60+ countries and 18 years of innovation, Antenk is your trusted partner for SMT‑ready, space‑saving battery holders.
