Advantages Of Hot Air Reworking
For speedy completion of modest tasks, hot-air rework stations are perfect. An old circuit board’s components are easy to remove with the use of a hot air . Even though this method isn’t precisely surgical, it will still save you a lot of time, in fixing existing soldered components, and pieces that would otherwise have been thrown out with the circuit board. Another advantage of using a hot-air rework station is that it also functions as a soldering station. This means that you can quickly solder a resistor, for example, and solder on a new resistor to save time.
What Is PID Control
A feedback-based control loop mechanism known as a proportional-integral-derivative controller (PID controller or three-term controller) is frequently employed in industrial control systems and a number of other applications that call for constantly modulated control. With respect to a desired setpoint (SP) and a measured process variable (PV), a PID controller constantly calculates an error value (displaystyle e(t)) and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D, respectively).
Practically speaking, PID automatically corrects a control function in a precise and timely manner. A common example is the cruise control on a car, which would slow down if engine power was applied continuously while it ascended a slope. The PID algorithm of the controller returns the observed speed to the
Features
- heats up within 5 seconds
- automatically reach to set temperature when you pick up the handle
- when you put back the handle in the holder machine goes to cooling mode and fan spins until the temperature goes below 50 degree Celsius
- if the fan speed is too low at very high temperature the heating element shuts down and gives warning on LCD
- machine works based on PID hence it can hold the heating element at the set temperature
- RGB led which change color according to mode
