Abstract

patente de invenção: <B>"PROCESSO E APARELHO DE TRATAMENTO DE SUPERFìCIES METáLICAS POR VIA SECA"<D>. Nesse processo de tratamento de superfície por via seca de pelo menos uma parte de superficíe metálica, segundo o qual a parte é tratada a uma pressão vizinha da pressão atmosférica por um fluxo de gás de tratamento compreendendo espécies excitadas ou instáveis, se aumenta localmente a pressão do gás de tratamento sobre a parte de superfície metálica, de maneira a forçar as espécies químicas a se deslocarem segundo uma direção sensilvelmente perpendicular à superfície. Aplicação à soldadura à onda de componentes eletrónicos sobre placas de circuitos impressos.
