No-Clean Process for Reflow Soldering Meets Environmental, Efficiency Needs

摘要

At the end of 1995, manufacturers around the world will complete the first phase of efforts to eliminate chlorofluorcarbons (CFCs) from production activities. Some studies have linked CFCs to damage in the earth's ozone layer. Makers are halting use of these products as an environmental protection measure. Elimination of CFCs has led many manufacturers to adopt washing-free processes. Manufacturers have a choice of several heating methods for reflow soldering. With all these methods, nitrogen (N2) atmospheres contribute substantially to washing-free production.
