REFLOW SOLDERING CONDITIONS
n
(1)
Recommended Conditions for Reflow Soldering
A thermal condition system such as infrared radiation (IR) or hot blast shall be adopted,
and vapor heat transfer systems (VPS) are not recommended.
(2)
Reflow soldering shall be done within 2 cycles. Please make sure that the parts have
enough cooling time.
(3)
(a) The time of preheating from 105℃ to 200℃shall be within 180 seconds.
(b) The time of soldering temperature at 217℃ measured on capacitors’ top shall not
exceed tL (second).
(c) The peak temperature on capacitors’ top shall not exceed Tp(℃), and the time within
5℃ of actual peak temperature shall not exceed tp (second).
Classification Reflow Profile
*1. Average ramp-up rate is 3℃/second max.
*2. Ramp-down rate is 6℃/second max.
*3. Time from 25℃ to peak temperature is 8 minutes max.
