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.
