Semi-aqueous cleaning systems

Aqueous and semi-aqueous cleaning systems, used for printed circuit boards and other industrial degreasing operations (Mandich and Krulik, 1992 Davis et al., 1994)... [Pg.40]

Semi-aqueous cleaning systems are not forgiving of mediocre skills of process control. [Pg.118]

A process that has found widespread use in practice is semi-aqueous cleaning with ZESTRON FA. This cleaner was especially developed for removal of no-clean soldering fluxes in ultrasonic batch or spray under immersion cleaning systems. It is used in the cleaning bath, rinsed with demineralized water, and then dried with hot air (see scheme in Figure 14.8.13.). [Pg.913]

The emulsion can become something else — a foam. If the spray nozzles are not properly aimed (and sized) so that they act directly on collections of liquid and not on part surfaces, foam can be generated. Foam is a fearsome enemy in all cleaning systems. Foam is air and chemicals. When foam breaks in tbe rinse vessel by the air being removed, the cleaning chemicals remain on part surfaces as chemical-rich residues. Usually, when foam is noticed within the semi-aqueous process, the operating machine must be shut down and the system flushed with fresh water — else soiled parts will continue to be produced. [Pg.117]
