In PCB soldering temperature and time must be tightly controlled, if you aim for a better outcome. It’s a balancing act, indeed. PCB assemblies require processing at a high temperature for a long enough time period for good solder joints. But again overshooting the temperature or heating, the assembly too quickly can damage components. Also, insufficient heating can cause poor soldering and long-term reliability issues. The only way to get time and temperature just right is to measure and analyze. This is what is thermal profiling.
Take this quiz and check your knowledge about thermal profiling and check for yourself where you stand.
Hurray! Being one of the most significant aspects of solder reflow, it is quite a thing in the PCB world. And your knowledge of Thermal Profiling is above average. Balancing your boards on time and temperature should be your genre.
