BGA and odd-shape placement failures rarely start at reflow; they usually start at pickup. This post explains how specialized nozzles, machine settings, and inspection discipline separate stable lines from expensive guesswork.
Most nozzle failures start as boring contamination, then turn into placement drift, dropped parts, and expensive line stops. This guide explains how I would clean, inspect, and retire SMT vacuum nozzles before they start taxing yield.
Most SMT lines do not struggle because they lack nozzle options. They struggle because nozzle selection is treated as a setup detail instead of a process decision. This guide explains how to match pick and place nozzles to component geometry, vacuum behavior, and production risk.
A alimentação não é “apenas logística”. É uma cadeia de custódia mecânica que decide o seu tempo de atividade, os seus defeitos e o seu custo real por placa.
