Depending on the contamination, these and the saponifier
mixed with them are the ingredients used in the chemistry.
The more volatile components of the cleaner evaporate over time (the base saponifier
, an organic alcohol, and some of the water).
For these situations, additional chemical additives, such as saponifiers
and surfactants, can be used to assist in removing hard-to-clean residues.
Cleaning a mixed technology no-clean flux with saponifier
, followed by DI water steam (manual) and low-pressure sprays.
are designed to wet the wash water to get into tight, low standoff places.
In this instance we used Envirogold Envirosense 816 saponifier
at 10% in a 140[degrees]F bath, and then steam-cleaned the pallets with a PDQ Minimax 2 steamer (Figure 2).
Until recently, we successfully cleaned all of our products after soldering and touchup with water and a saponifier
in a batch cleaner.
Only a saponifier
, used at a low pressure at 60[degrees]C and then rinsed with steam and deionized (DI) water, was found to be an effective cleaning method.
#1, a 5 percent from Vendor A, and saponifier
#2, a 5 percent from Vendor B, were used in a standard, in-line aqueous cleaner at a 57.
Additionally, the label materials exhibit excellent resistance to harsh fluxes, cleaning agents, saponifiers
and wave solder environments, and resist all commonly used methods of cleaning, according to the company.
The large roots of this plant contain gentle saponifiers
that cleanse the hair without damage or leaving a residue.
Many chemicals, including flux-cleaning solutions, saponifiers
, mild acids and alkalis, do not affect the bond.
In response, the thermal environments encountered in manufacturing will change because of the higher temperatures required for no-lead soldering, which will influence the saponifiers
, cleaners and fluxes used.
