. In addition, the paste requires a demanding thermal profile with a rapid ramp-up from the 160-180°C plateau to 235°C. A typical reflow profile for eutectic tin-lead solder The no-lead solder paste profile preferred by Japanese manufacturers As these new process elements were being developed, it became apparent that
