The SAMA5D27 SOM1 can be soldered to the host PCB by using the standard and lead-free solder reflow profile. To
avoid damage to the module, follow the JEDEC recommendations as well as those listed below:
• Do not exceed the peak temperature (Tp) of 245ºC.
• Refer to the solder paste data sheet for specific reflow profile recommendations.
• Use no-clean flux solder paste.
• Use only one flow. If the PCB requires multiple flows, mount the module at the time of the final flow.
