Spray rinse

Use air knives or spray rinses above process tanks to rinse excess solution off a workpiece and into the process bath. 

Use spray rinses as the initial rinse after the process tank and before the dip tank. 

Initially the nickel-chromium plating process is designed to minimize the liquid loading to the waste treatment system. Counterflow rinsing, spray rinsing, and stagnant rinse recovery methods are employed in order to minimize the amount of wastes to be treated and allow as much treatment or retention time in the waste treatment system as is possible. 

The empty bottles from the transfer machine are inverted to drain the residual liquid, water-spray rinsed in a twist-rinser, and immediately refilled with unfermented cuvee. Formerly, the bottles were washed in a large... 

Often several different robotic transport systems are used to convey the wafers to and from locations inside the CMP tool. Most tools have two basic internal environments under which they must operate (1) a wet environment of multiple spray rinses, moist atmospheres, and high particle (slurry abrasive) conditions, and (2) a dry environment with an ultraclean low-particle...

The following is a brush-on type gel degreaser with good spray-rinse properties ... 

This degreaser is sufficiently viscous so that it will cling to a brush for use on vertical surfaces. Because of the water content in the above formula, it is comparatively less expensive and less hazardous than many other gel degreasers currently on the market. Monamulse 653-C permits the emulsified oily soil to be easily removed by spray rinsing, which normally follows a brush-on application. Also, application brushes can be rinsed clean under running water. 

The wet blasting process can be more adaptable than conventional dry blasting. Wet blasting can handle a wider range of abrasive materials, and a spray rinse automatically removes the blasting residue. 

In other embodiments, it is located as shown in Figure 3.3 — after the emulsion spray rinse. And in still other embodiments, in both places (Figure 3.4) and in others, neither (Figure 3.2). 

The vessel(s) in which spray rinsing is done are also open tanks with pressurized spray nozzles, such as found in aqueous or solvent cleaning lines,... 

Extremely low foaming surfactants and emulsifiers used in mechanical dishwashers, pressure sprays, rinse aids, and low foam cleaners.

A Yellow or white residues on copper surface. YeUow residue is usuaUy cuprous hydroxide. It is water insoluble and is left when boards are etched and alkah-cleaned. A white pre-dpitate wUl probably be cuprous chloride, which can remain after etching in solutions that are low in chloride ion and add. To eliminate both conditions, the solution in which the board is rinsed just before final water-spray rinsing should be 5 percent by volume hydrochloric acid. 

Screen-printed vinyl resists and dry-film photoresist are the most durable for deep etching or chem-milling. A dip in a 10 percent nitric or chromic add solution wUl remove residues from the surface or edges of conductor lines that may be left on some alloys. Dilute chromic add has also been used for this purpose. Spray rinse thoroughly with deionized water after etching. 

Frequently, waste streams can be eliminated or reduced by process modifications or improvements. A notable example of this is the use of save-rinse and spray-rinse tanks in plating lines. This measure brings about a substantial reduction in waste volume and frequently a net reduction in metal dragout.
