Reflow Soldering
TimoTwo reflow soldering specification¶
TimoTwo 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 TimoTwo module conforms to JSTD-020D1 standards for reflow temperatures.
