Types of Reflow Profile:
Ramp to Spike graph (RTS):
1)It is a linear graph. Starting at start of segment and ending at peak temperature, the soak period is part of ramp.
2)RTS profile is easy to set, but it is difficult to control the quality by this setting.
Ramp – Soak – Spike graph (RSS):
1)In this type of graph the soaking period is easily noticeable and it will allow sufficient time to assemblies to reach equilibrium of temperature.
2)RSS type of graph is difficult to set, but through this graph we can control the quality of product.
