Flux Solder Paste: Is used to improve soldering quality by cleaning and preparing the surfaces to be soldered. It helps reduce oxidation and ensures a better flow of solder onto the joint. Ideal for surface-mount and through-hole component soldering.

Liquid Flux: A fluid applied directly to PCB pads and components to improve solder wetting and prevent oxidation during the soldering process. Commonly used for rework and touch-up on fine-pitch and BGA components, making it essential for precise and clean soldering work.
