Wafer-level accuracy isn&rsquo;t optional—a few degrees of drift will move bump height, shift registration, and knock yield right off spec. We built our lead-free solder wafer preheater to live in that reality.</h1> <p>O reflow de solda sem chumbo na linha de backend depende integralmente de um perfil térmico repetível. A precisão ao nível do wafer não é opcional—uma variação de alguns graus altera a altura do bump, desloca o registro e compromete o rendimento fora das especificações. Desenvolvemos nosso pré-aquecedor de wafer para solda sem chumbo para operar exatamente nesse cenário.</p>
