Description

Solvent vapor phase degreasing and desoldering composition, method, device and system Cross-reference to related applications

The present application claims the benefit of the Provisional Patent Application Nos. 61/978,278 and 62/110,037, filed on Apr. 11, 2014, the entire disclosure of which is hereby incorporated by reference. in.

In general, the present invention relates to compositions for vapor phase degreasing and desoldering of substrate materials, particularly solvents or cleaning compositions; and solvent cleaning methods, apparatus and systems.

Solvent vapor phase degreasing and desoldering is the immersion of oily substrates (eg, printed circuit boards or metal articles, glass, ceramic, plastic or elastomeric components or composites) such as certain chlorocarbon or chlorofluorocarbon fluids or Method of rinsing the component by immersion or distillate spray in a boiling liquid of the mixture, followed by a cleaning solvent in the second storage tank or cleaning zone using the same cleaning solvent as the chlorocarbon or chlorofluorocarbon used in the first cleaning zone . The components are then dried by maintaining the cooled components in the condensed vapor until the temperature reaches equilibrium.

Solvent cleaning of various types of components is typically carried out in batch, crane assisted batch, conveyor batch or inline conveyor degreaser and defluxing equipment. The in-line conveyor degreaser and the de-soldering apparatus are disclosed in U.S. Patent No. 5,007,179, entitled "Cold Air Lock Vapor Seal", assigned to the assignee of the present invention. Parts can also be cleaned in open top de-soldering or degreasing equipment, such as the US patents filed on September 25, 1990. Application No. 07/587,893 (now U.S. Patent No. 5,075,982) is also commonly assigned. In both types of equipment, the inlet and/or outlet ends of the equipment are typically in open communication with the surrounding environment and the solvent within the equipment. In order to minimize solvent loss from equipment by convection or diffusion, it is customary in the art to use water cooled or refrigerant cooled coils in the heat or environmental zone of the degreaser/desolder tank. A vapor blanket is produced, as disclosed in U.S. Patent No. 4,261,111, the disclosure of which is incorporated herein by reference.

Therefore, in the aforementioned solvent vapor phase degreasing method, it is generally known to perform a cleaning, rinsing, and drying step using a single organic chlorocarbon or chlorofluorocarbon (CFC) fluid. In the past, CFC-113 and Freon-based solvents were particularly popular. However, it has been implied that one of the many possible causes of the undesired global depletion of vapor diffusion into the environment as stratospheric ozone.

In response to environmental issues, certain hydrochlorofluorocarbon (HCFC)-based solvents have been developed to provide a more environmentally acceptable alternative to CFC-based gas phase degreasing and desoldering methods. While these materials have been shown to be excellent replacements for pre-used CFC materials in a variety of cleaning applications, they are only considered to be temporary replacements for their CFCs. To a large extent, this is due to the fact that the proposed material still has a small but limited ozone depletion potential, but is much less than the ozone depletion potential of its alternative CFC. Therefore, it is also proposed to phase out the use of some of these HCFC solvents in the future. It is generally believed that organic solvents that do not contain chlorine, bromine or iodine atoms will have a tendency to not cause depletion of stratospheric ozone. However, many organic chemicals, such as hydrocarbons, alcohols, esters, ethers, ketones, and the like, which do not contain the above halogen atoms, sometimes contain undesired flammability or reactivity characteristics. In addition, certain perfluorinated, saturated hydrocarbons and hydrofluorocarbons are known to have many desirable solvent characteristics, such as: zero ozone depletion potential; stable, non-reactive, high compatibility with plastics; good water exchange potential; generally non-toxic and Inert; and ideally suited for gas phase solvent cleaning equipment. However, many such perfluorocarbons have been found to be extremely poor solvents for many common organic and inorganic soils (e.g., fluxes). Although some hydrofluoric Carbon can provide improved but still limited cleaning capabilities over perfluorocarbons, but the concern has been that such materials will exhibit undesired flammability characteristics similar to their hydrocarbon analogs.

European Patent Publication No. 0 431 458, issued June 12, 1991, teaches the application of the formula C _n F _m H _2n+2-m aliphatic hydrofluorocarbons, of which 4≦n≦6 and 6≦m≦ 12. This reference teaches that aliphatic hydrofluorocarbons are active components in fluxes, fats, and oils and dusts that are removed from oily components. This reference teaches that in order to increase the solubility of the dissolved flux, an organic solvent selected from the group consisting of hydrocarbons, alcohols, esters and ketones can be added to the aliphatic hydrofluorocarbon in various amounts.

There are other types of cleaning methods, such as water cleaning. Water cleaning generally involves the step of cleaning the substrate or component in an aqueous solution of a cleaning agent or surfactant followed by multiple rinses with purified water. The part is then dried by ultra-long evaporation in air or by an energy intensive heat dryer. This approach is not always desirable due to the high energy costs for drying and the additional capital investment and operating cost burdens required by the state and authorities to remove wastewater solutions prior to discharge to groundwater.

Another cleaning method (half-water cleaning) consists of distilling, ester or petroleum distillation with high affinity based on, for example, oils, waxes and greases cleaned from the parts, with or without surfactant assistance. The substrate is cleaned in a hydrocarbon solvent. The cleaned substrate is rinsed with a plurality of rinsing steps in a high boiling hydrocarbon solvent using purified water. The hydrocarbon solvent phase is separated back into the wash puddle while the sewage must be treated before it is drained to groundwater. Therefore, the high costs associated with drying energy and treating waste liquids are evident, similar to the previously mentioned water cleaning methods. Another disadvantage is that hydrocarbon solvents typically have a flash point and this must be handled with care or covered with a non-combustible compressed gas such as nitrogen to avoid explosion. Nitrogen is less effective than the dense vapor of fluorocarbons contained in the condensing zone. In addition, in many applications, although the substrate to be cleaned can be compatible with hydrocarbon solvents, some plastics or metals can be incompatible with aqueous rinse solvents, resulting in water absorption or rusting of the substrate.

In certain preferred embodiments of the invention, the compositions described herein can be used to clean various soils (such as mineral oil), rosin-based fluxes, eucalyptus oils from various substrates by wiping, vapor degreasing, or other means. , solvents such as lubricants. In other embodiments, The compositions of the present invention are useful in vapor degreasers, particularly to remove solder flux and other residues from printed circuit boards and/or to remove oil or grease based residues from metal or non-metal surfaces. Figure 1 provides a partial illustration of a device that can be used in such a method. Here, the container 5 is divided into three puddles 10, 20 and 30, at least initially the compositions described herein are provided in all of the puddles. Each of the puddles is separated by puddle walls 35A and 35B, which have different sizes. As illustrated, in some aspects, wall 35A and wall 35B form three directional water puddles having different sizes such that fluid overflowing from puddle 30 flows into puddle 20 and from the puddle 20 overflowing fluid flows into the puddle 10. At least the puddle 10 further includes a heater element 40.

Initially, each of the puddles 10, 20, and 30 contained the same ratio of components of the compositions described herein. However, over time, the heater 40 in the puddle 10 heats the composition to a higher level than the first component and the third component in the first aspect or higher than the second component. (i) the boiling point, but lower than the boiling point of the second component. This causes the first component and the third component (either alone or as an azeotrope-like composition) or component (i) (if a second aspect is present) to boil and overflow from the puddle 10. These vapors eventually condense on the coil 50 and return to at least one of the puddles. In some aspects, the coil can include a population of upper coil 50A and lower coil 50B. The puddles 30 continue to cascade to the puddle 20 and ultimately to the puddle 10. In this case, the concentration in the puddle will vary so that the puddles 20 and 30 contain more of the first component and the third component or the second component in the case of the first aspect. Sub-(i), and the puddle 10 contains more second components.

In this embodiment, the puddle 10 provides an area in which most of the soil and organic cleaning agent can be submerged into the fluid composition of the present invention and/or by the spray stream placed in the composition of the present invention. Washed from a substrate (eg, a printed circuit board coated with a rosin-based flux or other residue, or a metal or non-metallic component coated with petroleum, synthetic or semi-synthetic oil or grease) The contaminated liquid falls into the puddle 10 below. Subsequently, the substrate is rinsed in the puddles 20 and 30 to clean the parts and remove unwanted debris Slag. The components may be dried by being held over one of the puddles (especially the puddles 20 or 30) and/or by evaporation in a known manner.

The parts or substrates to be cleaned can be transferred between the puddle 10 and the puddles 10, 20 and 30 using known conveyor belts or crane members. The sump may be part of a conventional or known in-line belt degreasing/desolding apparatus, a separate open top desolder sump or an open top desolder sump modified to contain a cleaning and rinsing tank or puddle.

In certain preferred aspects of the invention, the component is under the vapor coating or in the first component and the third component of the first aspect of the puddle 10 (either alone or as an azeotrope) The portion of component (i) in the case of the composition or the second aspect forms (at least partially) dried in the vapor zone 45. In some aspects, the vapor zone is free or substantially free of the second component. As used herein, when referring to a second component in a vapor zone, "substantially free" means that the amount of the second component present is sufficiently low to render the vapor composition non-flammable or otherwise cause The flammability of the vapor zone is not substantially or even better without the ease of measurement compared to the flammability of the vapor zone in the absence of the second component.

This vapor coating is advantageous because it reduces or reduces the flammability of the third component and/or minimizes the likelihood of explosion. However, in some aspects it may also include one or more additional inert materials. Such materials may include, but are not limited to, one or more of nitrogen, carbon dioxide, perfluorocarbon, hydrofluorocarbon or hydrochlorocarbon.

As illustrated, vapor zone 45 is formed over respective puddles 10, 20, and 30. A cooling coil 50, as the case may be, which is of the type known in the art, such as disclosed in U.S. Patent No. 4,261,111, the disclosure of which is incorporated herein in its entirety by reference in its entirety in its entirety herein In order to return the condensate to the puddles 10, 20 or 30, it is preferred that the puddles 10 or 30 are in the optimum puddle 30. The concentration of component (i) in the first component and the third component (either alone or as an azeotropic composition) or in the second aspect of the vapor zone 45 can be returned to the vessel 5 by vapor condensate to The fluid is pumped from the puddle 10 to the puddles 20 and/or 30 in the puddles and/or via a control volume or water level induction transducer (not shown) to maintain At a relatively constant concentration.

The invention is not limited to the three puddle configurations as discussed above and illustrated in FIG. In fact, two puddle configurations and four puddle configurations are also contemplated.
