PID Controlled Solder Paste Fridge
If you are work on surface mount electronic components here is a nice project.Jeff Keyzer writes:
Solder paste is a little tricky to handle, because most solder paste needs to be refrigerated at 32-50ยฐF to maintain itโ€™s shelf life. Stored at room temp, it tends to get tacky and dry out within a few weeks. Solder paste is also toxic (it contains lead among other things) so itโ€™s not something you want to put in the fridge with your meatloaf.
A proportionalโ€“integralโ€“derivative controller (PID controller) is a generic control loop feedback mechanism widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly.
