Recommended Guidelines

1.

 Place the Thermocouple (TC) as near as possible to the component being worked on.

2.

 If there are any sensitive components, use the Auxiliary Thermocouple as protection.

    You can select the protection temperature in 

Station settings. 

If the selected temperature is  

    reached, the Heater Unit will stop the process and a warning message will be shown.

3.

 IPC*  does not recommend exceeding ramp-up rates over 3 - 4 °C / sec (5 - 7 °F / sec) so as to  

    reduce the risk of thermal stress on the PCB.

* IPC was founded in the U.S. in 1957 as the Institute for Printed Circuits.

Auxiliary Thermocouple (TC)

Profiles by Temperature

Why Infrared? The most efficient technology for PCB preheating

Operation

The usual way to run a profile is using the Thermocouple (TC) connected to the Control Input of the 
console. JBC offers 3 predefined profiles (JBCset) and 10 profiles ready for you to personalize.

    JBCset profiles

    There are 3 profiles predefined by JBC: A, B and C. The difference between them is the number
    of steps: 2, 3 or 4. The thicker your PCB is and the more layers it contains, the more steps are 
    needed to obtain a gradual warming.
    These profiles are not modifiable but they can be used as a template to create your own profiles.

JBCset A

2 steps

JBCset B

3 steps

JBCset C

4 steps

This is the most advanced, efficient and cost-effective method to preheat PCBs in any soldering 
job or rework job. The low thermal mass of the infrared element gives outstanding control of the 
heat output and the process temperature. This technology provides fast response, high heating 
rates and uniform heating that ensure the best results.

For repetitive jobs 

we recommend

 running profiles without the Thermocouple (TC). Once 

     any profile has been run to the end, the system has all the process data which you can save.
     Once it is saved, you can run this profile without connecting the Thermocouple (TC). The 
     heating process will the same as long as the same working conditions are respected.

     User profiles

     You can create your own profiles from the JBCset profiles. On the work screen of the profile,
     press the 

Enter

 button and choose the option 

Edit profile.

Power Mode

The unit works at the selected power during the defined time. These parameters can be modified 
from the work screen by pressing the 

Enter

 button and the 

Edit parameters 

menu

.

To see the current temperature you must plug the Thermocouple (TC) into the Control connector.
