So preheating and gradual cooling process is suggested. IR soldering has the highest yields due to controlled heating rates and solder liquidus times. Make sure that the element is not subjected to a thermal gradient steeper than 3 degrees per second. 2 degrees per second is the ideal gradient. During the soldering process, pre- heating to within 175 degrees of the solders peak temperature is essential to minimize thermal shock. 4 - Soldering recommend paste is Sn 96.5/Ag 3.5 Peak Temp. 275 260C - Preheat (3 to 10sec) 250 1.The temperature rising speed is suggested to be 2~3C/s. 2.Appropriate preheat time will be from 60 to 120 seconds. 225 3.Temp. maintain at 175 +/-25C 120 seconds. 200 - Heating 175 1.Careful about sudden rise in temperature as it may worsen Peak Temp. 150 the solder ability. 245C 125 (10 to 20sec) Peak Temp. 2.Set the peak temperature in 235C 10-20s or 260C 3-10s. 175C 100 - Cooling (60 to 120sec) 75 1.Ramp down rate 6C/s max. 25 Perform adequate test in advance as the reflow temperature 01:00:00 02:00:00 03:00:00 04:00:00 profile will vary according to the conditions of the manufacturing Time (mn) process, and the specification of the reflow furnace 4 - Wave Soldering Process Peak Temp. 260C 275 (3 to 10sec) Ramp-up rate 3C/s max. 250 Temp. maintain at 175 +/-25C 180 seconds max. 225 Peak temperature 260C 3-10s.
