PERFORMANCE CHARACTERISTICS OF THE AQP AND SMA
The AQP and SMA are both aqueous chemistries that are designed for use
in ultrasonic cleaners, Both will clean a variety of soils, including solder paste, flux, and SMD adhesives. They
can be used to manually clean these soils by spray and wipe method, or as saturated wipes, but we originally
developed them for use in ultrasonic cleaning equipment. The matrix below shows some of the basic differences
between the features if the two products.

|
Requires Heat
|
yes
|
no
|
Both work better with heat, ultrasonic cavitation works best with heat
|
|
