Addressing the pain points of high manual soldering costs and high rework rates for multi-pin connectors, this summary focuses on optimizing the practical wire feeding methods for solder wire, and proposes 6 immediately implementable cost-reduction actions, covering key links such as soldering tip selection, flux dosage control, and solder feeding rhythm adjustment. A single action can reduce the manual time for a single solder joint by up to 32%, saving over 1400 hours of rework time annually.
Published: 2026-08-27Low-smoke solder wire for connector soldering is designed for high-volume automated soldering lines, addressing the pain points of traditional solder wires such as heavy smoke, excessive spatter, and poor wettability. It significantly reduces TVOC concentrations in the operation area while ensuring high electrical conductivity and mechanical strength. Compatible with automatic wire feeders for wire diameters ranging from 0.3 to 1.2 mm, it has achieved stable continuous feeding for 8 hours without downtime on customer production lines of Jiajinyuan.
Published: 2024-05-27Connector solder is specifically designed for welding various electronic connector terminals, featuring excellent wettability, low void rate, and strong thermal shock resistance. It is suitable for high-density connection scenarios such as FPC, board-to-board, and wire-to-board, and exhibits stable thrust and low cold solder joint rate in both reflow soldering and selective wave soldering processes, making it a critical solder material for ensuring the long-term insertion and removal reliability and signal integrity of connectors.
Published: 2021-08-28Using lead-free solder in the tin dipping process can significantly improve the solderability and corrosion resistance of wiring harness connector terminals, meeting RoHS environmental protection requirements. Jiajinyuan SAC305 series lead-free solder achieves uniform coating thickness control of 8-12 μm at a melting point of 183°C, adapting to the cycle time of continuous tin dipping production lines for terminals with wire diameters of 0.3mm-1.2mm.
Published: 2020-09-26Connector solder must balance wettability, residue control, and thermal shock resistance. Jia Jinyuan solder wires and bars can achieve capillary filling within 0.3 seconds in terminal dip soldering, maintain a bridging rate below 0.08% at an automatic soldering track speed of 1.2 m/min, and meet the dual-mode soldering requirements of 0.5mm-pitch FPC connectors and IDC crimp terminals.
Published: 2018-01-17High tensile strength of connector solder joints directly improves the reliability of the whole machine. Jiajinyuan connector solder, by optimizing the ratio of tin-silver-copper and active flux components, achieves an average tensile strength ≥8.2N at a conventional reflow peak temperature of 235℃, with no solder joint detachment, no cold solder joint, and no solder joint cracks after 100 insertion and removal cycles. It is especially suitable for industrial control and automotive electronics production lines under high-frequency vibration conditions.
Published: 2016-08-02The production of export wiring harness connectors must comply with the RoHS lead-free regulations, and connector solder must adopt compliant ratios such as Sn96.5/Ag3.0/Cu0.5. Jiajinyuan solder has stable wettability at a peak temperature of 245℃, and is compatible with terminal crimping and reflow soldering of multiple specifications with wire diameters ranging from 0.13 to 2.5mm. In mass production, the defect rates of solder balls, cold soldering, insufficient solder climbing and other defects are controlled within 800ppm.
Published: 2015-05-10Addressing the local soldering challenges of industrial control board connectors, selective wave soldering achieves high-reliability soldering through precise temperature control and solder wave positioning, while avoiding overheating damage to sensitive components across the entire board. Jiajinyuan equipment stably achieves a 99.7% first-pass yield under conditions of 0.8mm pin pitch and 12mm pad length, with a process window widened by 35% compared to traditional wave soldering, making it particularly suitable for the mixed assembly requirements of multilayer boards + high-density connectors in domestic substitution.
