ALPHA 2110 Aqueous Rosin Cleaner
GENERAL DESCRIPTION
Alpha 2110 is a cleaning concentrate designed forefficient removal of rosin flux residues from printed circuit boards using aqueous saponification processing.  In conveyorized, in-line aqueous machines, Alpha 2110 will provide excellent cleaning of assemblies, even to ionic
cleanliness standards set forth in MIL-P-28809. 2110 is formulated to maintain its composition in the recirculated wash solution during prolonged use, thus greatly reducing makeup additions normally required.Alpha 2110 works without the use of silicone defoamers.If excessive levels of foaming is observed while using Alpha 2110, consider the use of K-2235LF saponifier.Alpha 2110 removes rosin flux residues primarily by forming water soluble rosin soaps.
FEATURES & BENEFITS
•  Cleans rosin flux residues in water solution.  Proven alternative to solvent cleaning.
•  Most widely used product of this type.  Safe and effective, even for high reliability assemblies.
•  A concentrate used at 3-5% in conveyorized cleaners. Cost-effective and simple to use.
•  Phase II Approved.
AQUEOUS CLEANING WITH 2110
While designed for use in conveyorized cleaning equipment, Alpha 2110 can also be used in batch soak tanks and modified dishwater units.  Tap water is recommended for the wash solution.
Suggested use levels of 2110, by volume: 
Conveyorized Machines:             3 - 5%
Soak Tanks:                        4 - 8%
Dishwashers:                       2 -3%
The proper level of 2110 concentration will depend onsuch variables as throughput of printed wiring assemblies, wash temperature and wash time.  In order to effectively clean reflowed rosin solder paste residue, a 10% concentration of Alpha 2110 is recommended. Recommended wash tank temperatures are 150-160°F. Higher temperatures speed the saponification reaction.
Temperatures of 160-170°F are sometimes necessary for simultaneous removal of stabilizer waxes and temporary solder masks.  Alpha 2110 has excellent solution stability, even at these elevated temperatures, as well as low-odor characteristics.
Multi-stage rinsing of assemblies cleaned with 2110 can be accomplished with hot tap water or DI water, depending upon the level of cleanliness sought  (in general, the use of DI water is most appropriate and is recommended to ensure a high level of ionic cleanliness).   After hot air drying, the ionic cleanliness level achieved by aqueous cleaning with 2110 can be
measured with an Alpha Ionograph or Omegameter. The Alpha Sirometer can greatly facilitate measurement of test assemblies for surface insulation resistance under high temperature and humidity conditions.
