Laird surface mount modules are designed to be easily manufactured, including reflow soldering to a PCB. Ultimately
it is 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. Laird surface mount modules conform to J-STD-020D1 standards
for reflow temperatures.
Important: During reflow, modules should not be above 260° and not for more than 30 seconds.
