When cleaning assemblies (PCB cleaning, PCBA cleaning), the primary goal is to remove resin and flux residues from populated boards and hybrids as well as production related residues created by handling. Even though in many low-end production processes the use of "no-clean" works well, high-end assemblies that will be employed in industries such as automotive, telecommunications, military, and aerospace, require the use of a specific PCB cleaning agent.
When employing modern PCB cleaning agents, these problems can be avoided as they are able to remove most current flux residues. ZESTRON and cleaning agents can be used in aqueous as well as semi-aqueous and water-free cleaning processes. For cleaning lead-free as well as leaded assemblies, various cleaning machines and process types are available.
