Benefits of Liquid soldering flux
Posted by Alphaassembly on July 26th, 2017
Liquid solder flux is necessary in the soldering process, since solder does not always adhere properly to components because of the impurities and oxide buildup during soldering, resulting in poorly soldered joints, bridging, absence of joints and other soldering defects. Liquid soldering flux is an agent that fixes bonding issues, and with the right temperature, it ensures a properly formed joint. Flux acts to clean the impurities and oxides, which form as solder melts. After doing its job, it stays on the metal’s surface during the soldering process to prevent oxides from forming further.
Environmentally friendly fluxes are ideal for wave soldering processes. High-quality alcohol-based fluxes ensures defect-free soldering and excellent wetting making them ideal for high-line throughput processes across different applications. Alcohol-based fluxes can be a suitable alternative to conventional fluxes for a range of assembly types (i.e. I, II, III, and IV.) Reputable manufacturers use the latest flux technology to create liquid soldering flux based on strict standards that guarantee unmatched consistency and the highest-quality product.
Liquid soldering flux types come in low-VOC and water-based formulations. Low-VOC liquid soldering flux contains rosin and requires no cleaning, with low solids content and compatible with moderate pin testability. It is designed for all-around performance like alcohol-based fluxes. The unique formulation ensures consistent deposits of fluxes and the absence of buildup around spray nozzles. Water-based liquid soldering flux is either water soluble or rosin-free and no-clean. Pin testability is high. Some formulations come with proprietary additives to minimize surface tension between the solder and the solder mask that minimizes the generation of solder balls.
Liquid soldering flux may come in many different formulations. Choosing the right liquid soldering flux should increase the value of the selective soldering application by increasing yield and throughput.
