COBAR REGI-RED 1L Bottle
REGI-RED is an alcohol-based flux for many soldering tasks where a halogen-free process and a clean solder joint are desired. It is classified ORL0 according to IPC-J-STD-004-A and is based on organic acids. In practice, this means that the flux is designed to help the solder flow correctly while leaving minimal visible residues.
This type of flux is particularly useful when challenges with bridging between conductors can arise. REGI-RED is relevant here because it is formulated to counteract bridging while promoting wicking, meaning the solder is drawn to where it needs to be. This makes it suitable for processes with multiple reflow or wave soldering steps, where the flux must be able to perform stably throughout the entire process.
For the professional user, it is precisely the combination of halogen-free composition, low visible residue, and good process behavior that makes the product interesting. It is not designed to impress on paper, but to function in a typical production situation where solder quality and subsequent cleaning requirements must be balanced.
