MultiEx^® 3D-A3
Special detergent for PCBAs, power electronics, solder frames and carriers

MultiEx^® 3D-A3 is an aqueous, alkaline special cleaner for the thorough and gentle cleaning of power electronics / DCBs.

MultiEx^® 3D-A3 reliably removes flux residues and metal oxides (e.g. copper or aluminum oxide) and at the same time protects against re-oxidation of the metal surfaces.

MultiEx^® 3D-A3 works in three dimensions.
Dimension 1: Flux removal. Flux residues are removed, minimizing the risk of electrical malfunctions due to corrosion. 
Dimension 2: Deoxidation of the metal surfaces. Metal oxides are removed so that electrical conductivity is not negatively affected and soldering can be carried out reliably if required.
Dimension 3: Passivation. The deoxidized metal surfaces are passivated so that cleaned and deoxidized metal surfaces remain oxide-free for longer.

MultiEx^® 3D-A3 special and unique priming formulation ensures that - without any detectable surface coating - cleaned and deoxidized metal surfaces do not tarnish again.

MultiEx^®®3D-H2 is equipped with TernarySequence^®® three-phase regeneration technology and TS+ buffer making it even more efficient.

MultiEx^® 3D-A3 is supplied as a ready-to-use mixture (ReadyMix) for direct use in kolb cleaning systems with PowerSpray^® technology and all other common pressure spray cleaning systems.
