PROMOSOLV 70ES T

Removal of flux residues
Vapor phase process
Made from recycled solvent

PROMOSOLV 70ES T is the recycled version (made from recycled solvent) of PROMOSOLV 70ES. This product is the result from our ECOPROGRAM initiative and offers the same performance as the original product.

PROMOSOLV 70ES T is developed as a drop-in replacement for trichlorethylene, NPB and other solvent. While reducing substantially the HSE impact, the defluxing power is at an equivalent level.

It is dedicated for removing reflowed flux residues and other contaminants on PCBA’s, power modules, lead frames, BGA’s, PoP, SIP applications or LED assemblies. Its low surface tension allows very well cleaning and rinsing under low stand-off components and difficult to reach spaces. It has very good compatible with all metals, including very sensitive ones and also with most plastics & elastomers, however recommended to validate before use.

PROMOSOLV 70ES T is formulated with safety in mind. Its composition gives excellent flammability suppression properties, which provides a very high stability when used in an equipment. Some products in the market may loose their flammability suppression compound due to evaporation when used in an equipment.

Process examples

The best process will depend on factors such as operating conditions, equipment, desired cleaning time and the nature of contaminants. Our team is ready to advise you.

Removal of flux residues

Do not remove parts too quick out of the drying zone to prevent unwanted loss of solvent.
Compatibility report with different materials is available on request.
In case of very heavy production load, Promosolv AD70 additive can be added to increase solubility of solder fluxes.
It’s recommended to work with a siliporite filter to separate water from the condensation loop.
