Corroendo Placas de Circuito Impresso PCI.MOV

Este video mostra a preparação da solução que corroe as placas que são feitas nas aulas de eletrônica. No preparo da solução é necessário CUIDADO, pois estamos trabalhando com um ácido, mais precisamente, o PERCLORATO DE FERRO, que ao entrar em contato com água exala uma fumaça não-tóxica, e aumenta a temperatura da solução. Após a mistura, como vemos no video, colocam-se as placas e após 20 minutos, em média, a placa estara pronta.
O ‘estar pronta’, me refiro a corroção da parte que você não protegeu com a caneta especial, chamada de marcador para placas de circuito impresso 2mm. Essa parte que você protege, o acido não corroe, permanenencod assim esse cobre, que servira para conduzir a eletricidade atraves dos componentes que serão soldados nessa placa.
