or time is too long, will cause flux volatile prematurely, and then lead to
oxidation and poor wetting;
Ref
: Reflowing section, this section is mainly used to melt the solder paste,
it’s a key step in welding, temperature rise rate is greater than the previous,
too high temperature and too long time will lead to oxidation and impact of
components on circuit board;
RefKp
: Reflowing keep section, used to set the time to maintain the
maximum temperature for full of flux volatile and solder flow;
Cool
: Cooling section, mainly used to reduce the temperature of the circuit
board smoothly, solder will be re-solidified in this process, it is worth
mentioning that the cooling process also has a great impact on the welding
effect, too fast or too slow cooling process will produce pale and lightless
solder beads, what is worse, there may be potential defects;
Melt
: Melting point, in fact, the solder paste has strict requirements on time
that the temperature above the melting point.
