You can see 2.5F MultiTC at work:

• reflow soldering an LCFesR meter's SMD PCB in an reflow oven;
• works as PID controller in PID=ON mode to hold a preset temperature;
• and how to change MultiTC's parameters in this video:

In this video you can see MultiTC PID controller working for BGA rework. I used a cooker as preheater under the PC board - here I preheated the PC board to 150°C. Then I started the BGA lead-free rework (that is desoldering / soldering) PROGRAM to remove the BGA off the PC board by heating the BGA with a 75W / 220V halogen bulb. The program's profil is the next: heat the BGA to 180°C, hold this for 60s to stabilize the BGA's temperature, heat the BGA to 200°C, hold this for 30s to stabilize the BGA's temperature, heat the BGA to 235°C, hold this for 30s, then switch the halogen bulb off; of course all these parameters can be reprogrammed and saved to MultiTC EEPROM. I choose this type of bulb because it is cheap (about 6-7 Euros), it matches well the BGA size so other components around the BGA are less affected by high heat and no ventillator is needed to cool the bulb for its work. Of course a higher wattage halogen bulb, ex. 100W-250W or an IR ceramic heater can be used - but they are bigger and much more expensive. I think the equipment is a very cheap but well working BGA rework station and it's maintenance (exchange of halogen bulb) is cheap too. Of course with some futher assembling works, the equipment would look like a real station. I have not made any video about soldering the BGA but the process is the same like what you see in this video!
