Methane sulfonic acid (MSA) is a relatively expensive acid used to strip (remove) solder (tin/lead) and copper metals. This acid is also used to condition metal surfaces prior to fluoborate free-solder electroplating when applying a final etch resist of solder onto multilayer printed circuit boards. By continuously recirculating the acid bath through a diffusion dialysis unit, a 95 percent reduction of chemical purchases (required by the process steps indicated in the first paragraph of this section) may result, producing less than a six-month return on the initial capital investment (ROI). Typically, 80 to 90 percent of the acid is recovered with 70 to 90 percent of the metals removed in an equal volume of dilute acid. Another system uses only water in its process. The heart of this product is a shallow bed of special adsorption resin. This resin has the unique ability to adsorb strong mineral acids yet exclude metal salts. This is not an ion exchange process since only water is used, in a countercurrent fashion, to desorb the acid from the resin. 60.5.2.3 In-tank Electrolytic Permanganate Regeneration. Because permanganate is a powerful oxidizing agent only in basic conditions, desmear solutions usually contain 5 to 10 percent caustic soda. However, the alkalinity at high temperatures causes the permanganate (MnO4 1) ion to break down to manganate. The manganate reacts with water to form manganese dioxide (MnO2), eventually forming a black sludge of MnO2 which settles to the bottom of the desmear tank. This requires that the bath be dumped. Oxidizing electrolytic regeneration systems are available to inhibit this reaction. A typical electrolytic regeneration system employs an in-tank probe composed of a copper rod as the cathode which is connected to a power supply. When current is applied, oxygen is generated in the permanganate solution which functions as the regenerate for the manganate. The efficiency of the system depends on the rate of manganate buildup, the amount of amperage generated, and the power supply to the in-tank regenerator. These probes attach to the top rim of the desmear tank and are always operating (as the permanganate ions will break down even when the bath is not active). In most cases, the use of this equipment has eliminated the need to dump this bath. 60.5.2.4 Proper Rack Design and Maintenance. By using plastic-coated racks, only the tips and contactors (which electrically and physically connect and support the panel to the carrying rack), have exposed conductive metal and must be stripped. If one of these is removable, then the amount of metal to be chemically or electronically removed from the rack is also reduced. This should lengthen the useful life of the stripping bath and further reduce the cost for hauling away or on-site treatment (if nitric acid is used) of the spent rack stripper. Use of racks with disposable contactors eliminates the need to strip the racks and could eliminate the use of nitric acid. 60.5.2.5 Dragout Recovery Tanks. The dragout tank s primary purpose is to collect most of the solution dragout before the panel enters the rinse tank. The dragout (recovery) tank is a rinse tank that operates without a continuous flow of feed water. It is positioned between a process bath and its rinse tank. The dragout tank can be either an immersion application (for the electroless and innerlayer operations) or a spray type application (on conveyorized equipment or for pattern- or panel-plating operations). After the panels have been removed from the process bath, they are immersed or sprayed in the dragout tank before they are rinsed in another tank.The concentrated rinse water can be collected separately from its following rinse.
