1. Product Overview
VIGON® A 201 is a water-based, alkaline defluxing agent specifically formulated for spray-in-air processes. It delivers exceptional cleaning performance under low standoff components, including Micro BGAs, Flip Chips, and 01005 components. The MPC®-based formulation efficiently removes flux residues from leaded and lead-free No-Clean solder pastes, leaving shiny solder joints without additional additives. VIGON® A 201 ensures high material compatibility, enhances wire bonding quality, improves optical performance in Power LEDs, and extends bath life in closed-loop systems.
2. Applications
Spray-in-air inline and batch cleaning of PCBAs, Flip Chips, CMOS, and Power LEDs.
Effective removal of flux residues from leaded and lead-free No-Clean solder pastes.
Cleaning of capillary spaces and low standoff components, ensuring void-free underfills.
Optimizes die attach, wire bonding, and light conversion efficiency in Power LEDs.
Can be used with process monitoring and regeneration systems (ZESTRON® EYE, Bath Analyzer 10, Adsorber HM1) for stable operation.
