The refined development of electronic welding and the iterative upgrading of flux series to meet the

As the core auxiliary material of electronic soldering, flux series products have achieved a breakthrough in the performance of "low residue, high activity, and no corrosion" through technological iterative upgrading, and accurately adapt to the soldering needs of micro components and high-density PCB boards. In high-end manufacturing fields such as smartphones, tablets, automotive electronics, aerospace electronics, etc., the size of components is shrinking, the pin spacing is becoming denser, and the problems of traditional flux such as many residues, strong corrosiveness, and low soldering efficiency can easily lead to false soldering, short circuit, and reduced reliability of solder joints, which seriously affects product quality.

The technological innovation of the flux series is mainly reflected in four aspects: first, the optimization of active ingredients, the use of new environmentally friendly active agents, while reducing the soldering temperature (as low as 180°C), greatly improving the welding capacity, can quickly remove the oxide layer on the metal surface, and ensure that the solder joints are full, bright and strong; The second is the low residue and non-corrosion design, by accurately adjusting the formula ratio, the product has a very low residue after soldering, no need for additional cleaning, or only simple cleaning to meet the industry standard, and is non-corrosive to the PCB board and component pins, avoiding performance attenuation after long-term use; third, adapt to lead-free soldering process, develop special lead-free flux, comply with RoHS, WEEE and other environmental protection standards, and meet the needs of lead-free transformation in the electronics manufacturing industry; Fourth, adapt to automated production, launch spray type, foaming type, no-cleaning type and other forms, which can be perfectly compatible with wave soldering, reflow soldering and other automated welding equipment to improve welding efficiency and consistency. In terms of application scenarios, the flux series has covered many fields such as consumer electronics, automotive electronics, industrial control, and aerospace, providing precise soldering solutions from micro sensor soldering to large-scale PCB board assembly. With the continuous refinement of the electronic soldering process, the flux series will further develop in the direction of "high activity, low residue, environmental protection, and customization", providing core support for the high-quality development of the electronic manufacturing industry.
