Reflow soldering specification¶
MLE-N2 is a surface mounted device (SMD) designed to be easily integrated into high-volume production lines including reflow soldering to a PCB. It is ultimately the responsibility of the customer to choose the appropriate solder paste and to ensure oven temperatures during reflow meet the requirements of the solder paste. The MLE-N2 module conforms to JSTD-020D1 standards for reflow temperatures.
Temperatures should not exceed the minimums or maximums presented in the table below
