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.

Performance Comparison between the AQP and SMA

Feature

AQP

SMA

Notes

Requires Heat

yes

no

Both work better with heat, ultrasonic cavitation works best with heat

Operating Temp

100ºF to 120ºF

Ambient to 100ºF

SMA doesn't require heat, but performance is enhanced with it

Dilution ratio

10-20%

5 to 7%

Always start with lower range, and do not increase above max range

SCAQMD Certified

Yes

No

California customers should note AQP is clean air certified by SCAQMD

Color

light amber

clear

SMA starts as clear liquid, turns cloudy with use

Odor

none

slight

SMA has slight odor

Cleans solder paste

yes

yes

yes

yes

cleans uncured fluxes manually, cured flux with ultrasonics

Cleans adhesives

some

yes

cleans uncured SMT adhesives manually, cured flux with ultrasonics
