When manually soldering mobile phone motherboards, thin-diameter solder wire can precisely cover pads below 0.3mm, avoiding bridging and cold solder joints. Combined with a constant-temperature soldering iron and a high-magnification microscope, it enables reliable connections of tiny solder joints such as peripheral resistors and capacitors around BGA and cable interfaces, making it an indispensable practical process for rework production lines to handle high-density PCBs.

Whether to choose solder wire or solder ribbon for manual welding is essentially a process matching issue. Solder wire is suitable for welding large solder joints and high-heat components, while solder ribbon, with its thinner flux core and more controllable solder output, is adapted for tiny surface-mount components such as 0402 and 0603. The selection of wire diameter must be comprehensively determined by considering the soldering iron power, pad size, and the operator's proficiency level.

This process has been batch verified on multiple new energy vehicle high-voltage wiring harness production lines of JJY.

When manually repairing circuit boards, the selection of solder wire diameter directly affects solder joint formation and rework yield. 0.3mm solder wire is suitable for fine touch-up soldering and jumper wiring of small-size SMD components such as 0402 and 0603, while 0.5mm solder wire is more suitable for rapid tinning of QFP pins, power ground pads and large-area copper foils. 20 years of production line tests by JJY show that there are significant differences in melting consistency and wetting spreading ability between the two under the conditions of soldering iron temperature of 320℃ and dwell time of 2 seconds.

Severe oxidation of solder bars directly leads to solder joint spikes, cold solder joints, and increased solder dross. Intervention must be carried out simultaneously from four aspects: storage environment, solder melting temperature, flux ratio, and squeegee maintenance. Among them, controlling the solder pot temperature at 250±5℃, using special flux containing antioxidant components, and keeping solder bars dry and sealed during storage are the three most effective practical measures to reduce solder oxidation.
