iFixit Rinseless flux

The iFixit soldering flux is designed for servicing and repairing fine electronics. Its main purpose is to improve the solder's wettability, which helps it flow evenly and promotes the formation of high-quality joints. Thanks to its no-clean formula, it leaves no residue after soldering that needs to be cleaned up. This makes it suitable for both professional technicians and hobbyists working with printed circuit boards (PCBs) and other sensitive components.

Clean work and reliable joints

Proper flux function is fundamental to successful soldering. This product actively prepares the surface of the solder pads and component leads, improving the adhesion of the molten solder. The result is a smooth and even flow, which is crucial for creating a mechanically strong and electrically conductive joint. A major advantage is the no-clean design of the flux. After finishing the job, there's no need to clean the circuit board of any remaining flux, which saves time and reduces the risk of damaging sensitive components.
