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 10000 square meter Huizhou facility, proudly presents the SINGLE BATTERY HOLDER FOR 18650 SMT. This surface mount holder is precision engineered for one 18650 lithium ion or lithium iron phosphate rechargeable cell measuring 18mm diameter by 65mm length – the most popular cylindrical cell for high capacity portable power. 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 rated UL94 V0 with a heat deflection temperature of 280 degrees Celsius, enabling fully automated pick and place and reflow soldering. The positive contact uses a robust dual beam stamped beryllium copper spring while the negative contact employs a high force captive coil spring, both finished with selective gold plating of 0.4 microns for ultra low resistance. Key characteristics include contact resistance below 15 milliohms, retention force of 300 to 450 grams capable of holding the heavier 18650 cell securely, continuous current rating of 5A peak 8A, a low profile of just 7.5mm above PCB, and an operating temperature range from -40 to +125 degrees Celsius. The integrated polarity key prevents reverse insertion. The product is RoHS and REACH compliant and UL recognized under E472792.
The single 18650 SMT holder is ideal for high volume automated assembly of portable high power devices such as rechargeable LED flashlights, power banks, cordless vacuum cleaners, portable medical ventilators, e-bike battery packs, wireless speakers, handheld industrial scanners, and IoT gateways with battery backup – 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 with 200 pieces per reel for automatic placement. Solder the two large SMT pads using standard reflow soldering with a peak of 260 degrees Celsius and recommended stencil thickness of 0.18mm for adequate solder volume. The LCP housing withstands reflow without warpage. After soldering, manually insert the 18650 battery with the positive button top end against the dual beam contact and the negative flat end against the coil spring – significant force is required to compress the heavy duty spring, and an audible click confirms full seating. The polarity key on the housing ensures correct orientation. To remove, use a plastic pry tool or dedicated battery extractor. Precautions: do not exceed 5A continuous current or 8A peak; avoid reflow soldering more than twice; do not use with unprotected cells that have shorter length; ensure the battery is fully seated before closing the device; operate within -40 to +125 degrees Celsius. Advantages over competitors: unlike competitors who offer only through hole 18650 holders that require board drilling and manual soldering, Antenks SMT version eliminates drilling and reduces placement time by 80 percent, making it ideal for high volume production. Competitors often use PBT that warps during reflow; Antenk uses LCP with 280 degree Celsius HDT and less than 0.05mm coplanarity after reflow. While others require 15000 plus MOQ for 18650 SMT tooling, Antenk offers low MOQs of 1000 units with no tooling fees for standard configurations. Our IATF16949 certification ensures automotive grade reliability, and our in house 40 plus lab test devices including XRF, environmental chambers, and 3D profilers guarantee every batch meets EIA 364 standards.
Antenks vertical integration delivers consistent quality for the 18650 SMT holder. Process flow: first, in house mold design using our 380 plus plastic injection molds with a dedicated 18650 cavity holding a tolerance of plus or minus 0.03mm on battery diameter and pad flatness. Second, injection molding on 10 Japanese Taiwanese 35 to 120 ton machines using LCP resin with melt temperature 330 degrees Celsius, mold temperature 120 degrees Celsius, and cycle time 16 seconds – the material is pre dried to prevent voids. Third, high speed stamping of positive dual beam beryllium copper contact and negative heavy duty spring contact on 9 Japanese Taiwanese presses using 0.30mm phosphor bronze strip for extra strength. Fourth, selective gold plating with nickel underplate of 2 microns and gold of 0.4 microns on all contact tips. Fifth, automated spring coiling on Japanese CNC coilers with a pitch tolerance of plus or minus 0.08mm and force validated to 300 to 450 grams. Sixth, semi automatic assembly including inserting contacts into LCP housing and ultrasonic staking for permanent retention. Seventh, 100 percent coplanarity inspection with all SMT pads within 0.08mm using a laser profilometer. Eighth, spring force testing per EIA 364 04 from 300 to 450 grams. Ninth, contact resistance testing per EIA 364 06 below 15 milliohms. Tenth, reflow simulation test at 260 degrees Celsius for three passes to verify no warpage or solder wicking. Eleventh, 48 hour salt spray corrosion testing on sample basis. Finally, tape and reel packaging with 200 pieces per reel and 100 percent visual and electrical verification. Our laboratory houses more than 40 testing devices including XRF, environmental chambers, and automated spring testers. With over 300 employees, more than 18 mold making machines, and over 180 automatic assembly machines, we provide free samples, complete 2D and 3D CAD drawings with recommended PCB land pattern, and 24 hour technical support. Contact Antenk today for a quotation – we respond within 4 hours and ship 18650 SMT holder samples within 5 days. Ask about volume discounts starting at 5000 units and custom options such as gold thickness, higher retention force, or high temperature LCP for lead free reflow.
