Cleaning agents with poor material compatibility can easily cause adverse phenomena such as oxidation, discoloration, swelling, deformation, or detachment of sensitive materials. The water-based cleaning agent developed by Unibright is an environmentally friendly cleaning agent developed for wire frames, power semiconductor devices, discrete devices, IGBT modules, power modules (optoelectronic modules, sensing modules, communication modules), and reflow soldering DCB post welding cleaning, which has good material compatibility and high cleaning efficiency. It avoids damage to sensitive materials while cleaning residues such as solder paste, flux, and solder paste.
