Manufactured by Huizhou Antenk Electronics Co., Ltd, the BHDM03 series 2.54mm 3M type SMT box header with 9.9mm overall height is a surface-mount box-style connector dedicated to stable signal and moderate-current PCB interconnection. According to drawing specifications, this box header supports contact counts ranging from 06 pins up to 64 pins with standard 2.54mm pitch. The insulator provides multiple material options including PBT, PA6T, PA46 and PA9T all blended with 30 percent glass fiber and complying with UL94V-0 flame retardant grade, alongside customizable black blue and gray housing colors. Brass pins can be finished with gold flash, selective gold plating of various thicknesses or tin over nickel plating to fit different anti-corrosion and conductive demands. Its electrical indicators cover 3.0A rated current, minimum 1000MΩ insulation resistance and maximum 20MΩ contact resistance, enduring 500V AC DC dielectric voltage and operating steadily between minus 40 degrees Celsius and 105 degrees Celsius. Multiple positioning notches are reserved on the housing to prevent reverse insertion during mating. Our complete production workflow includes independent precision mold development, high-speed brass terminal stamping, high-temperature plastic injection molding, anti-oxidation electroplating and automatic assembly. Imported Taiwan punching machines and Japanese injection molding equipment ensure all PCB layout dimensions stay within tight tolerances for automated reflow soldering.
This SMT box header offers abundant packaging selections such as tray, bag, tube, tube with cap, tape reel and tape reel with cap to match manual assembly and fully automatic SMT production lines. Operators align the SMT solder feet with designated pads on printed circuit boards following the official PCB layout drawing and finish reflow soldering, then insert matching male pin headers into the box cavity to form complete circuit connection. It is widely applied in industrial control modules, communication circuit boards, digital display equipment, smart household appliances, portable storage devices and precision testing instruments. During production and usage, users must strictly control reflow temperature curve to avoid glass-filled insulator deformation, avoid reverse plugging guided by the positioning notches, and store unused connectors in dry sealed packages to protect brass terminals from oxidation. All products comply with EU RoHS and REACH environmental regulations, most specifications obtain UL certification numbered E472792, and our factory holds ISO9001, ISO14001 and IATF16949 automotive quality management certifications.
Compared with other connector manufacturers, Antenk owns more than 250 sets of self-developed plastic molds and 180 sets of precision brass stamping molds, supporting flexible customization of pin quantity, insulator material, housing color and plating method for this box header series. Our 10000-square-meter manufacturing base with 250 professional staff is equipped with over 180 automatic assembly machines and 20 sets of professional testing instruments, guaranteeing consistent batch quality and fast delivery for large-volume orders. As a Guangdong Famous Trademark certified enterprise, more than 70 percent of our SMT connectors are exported to global markets. Our multi-stage incoming, in-process and finished product inspection system delivers excellent anti-misinsertion and vibration-resistant performance, effectively reducing poor contact and circuit disconnection risks and establishing long-term trusted cooperative partnerships with customers across Europe, America, Southeast Asia and other international regions.
