JBC PHBE-1A PHBE Preheater Unit

Product Information

The PHBE Preheater is a device designed for heating printed circuit boards (PCBs) up to 36x28cm/14×11 in size. It is available in three versions: PHBE-1A (120V), PHBE-2A (230V), and PHBE-9A (100V). The preheater unit comes with various accessories, including a console, RJ45 cable, power cord, Kapton tape, thermocouple, and a user manual.

Features and Connections

The preheater unit features two heating areas, four thermocouple connectors (Type K), an RJ12 connector for robot connection, an RJ45 connector for console connection, a USB-B connector, a pedal connector, fixing brackets for PHBS support, a main switch power socket, and a foot for vertical setup.

Work Screen

The console offers an intuitive user interface with a 2.8″ color TFT screen. It provides quick access to station parameters, status indicators, current temperature readings, and menu options. The console also supports multiple languages and system notifications.

Setting Thermocouples Function

The preheater unit allows you to set up the thermocouples for control and protection purposes. The TC1 thermocouple is always working in control mode for temperature and profile modes. You can select the temperature for each thermocouple from the work screen. It is recommended to place the control thermocouple near the component being worked on and use a thermocouple as protection for sensitive components.

Product Usage Instructions

Ensure that the power cord is properly connected to the preheater unit and a power source.
Place the PCB to be heated on the preheater unit within the specified size limit (36x28cm/14×11).
Connect the RJ45 cable from the preheater unit to the console.
If using a robot, connect the RJ12 connector from the preheater unit to the robot.
Turn on the main switch power socket of the preheater unit.
On the console, use the buttons and color TFT screen to navigate and access station parameters.
To set up the thermocouples, select “Thermocouples” from the Work mode menu on the console.
Follow the recommended guidelines for placing the control and protection thermocouples near the components being worked on.
Select the desired temperature mode (Temperature Mode) from the Work mode menu on the console.
The preheater unit will maintain the selected temperature for the control thermocouple (TC1) as long as the other thermocouples do not reach the control/protection temperature limit.

Setting Thermocouples Function

Select Thermocouples from the Work mode menu to set them up.
The thermocouples (TC) can work in three different ways depending on what is needed.
- Control: the unit maintains the selected temperature.
- Protection: the Heater Unit stops if the TC reaches the selected temperature.
- Info: the TC temperature is shown on the work screen.
The TC1 is always working in Control mode for the Temperature mode as well as for Profiles mode.
The temperature of each TC can also be selected from the work screen.

Recommended Guidelines

Place the control thermocouple as near as possible to the component being worked on.
If there are any sensitive components, use a thermocouple as protection. You can select the protection temperature in the thermocouples menu. If the selected temperature is reached, the Heater Unit will stop the process and a warning message will be shown.
We don’t 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.

Work Mode

Temperature Mode:

Select Temp. mode from the Work mode menu. In this mode, the heater unit maintains the selected temperature for the TC1 thermocouple as long as the other TC’s do not reach the control/protection temperature limit.

JBC-PHBE-1A-PHBE-Preheater-Unit-fig-9

Working within the Temperature mode the maximum heating rate value (Max Rate) can be defined (1).
This function allows you to set a maximum value for the temperature increase per second when heating.
The maximum heating rate value can be set between 0.1°C/s and 2.0°C/s (2) or “None” if this function is not desired.

Power Mode:
Select Power mode from the Work mode menu. In this mode, the heater unit maintains the selected power as long as the thermocouples do not reach the control/protection temperature limit.

Profile Modes
Select Profile Mode from the Work Mode Menu. In this mode the heater unit regulates the temperature of the TC1 thermocouple according to the selected profile as long as the other TCs do not reach the control/protection temperature limit.

Teach Profile

For repetitive jobs you running profiles without the thermocouple (TC). In order to do so, the Teach profile mode has to be executed before running any profile. It can be executed from the Work mode menu if the Profiles mode is selected.
Once the 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 be the same as long as the same working conditions are respected.
The profiles which already have the data from the Teach profile are marked with this symbol
These profiles can be run either with or without the Thermocouples. It can be chosen from the Profiles mode work screen:

Profile Editor

The Profile editor can be opened from the main menu or from the Profiles mode work screen by pressing the ‘OK’ button.
In this mode, you can edit as many as 25 profiles of temperature.

JBC Set 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 gradual warming.
These profiles are not modifiable but can be used as a template to create your own profiles.

Process Analysis

By pressing Graphics in the main MENU, the temperature of TC1 thermocouple and power fi gures in real time are displayed.

Update the Station Software

Download the JBC Update File from www.jbctools.com/software.html and save it on a USB flash drive. (Preferably one with no other files).
Insert the USB flash drive into the console. The icon is displayed while updating.

Working with Pedal

Press the pedal to start heating and press again to stop as if it were the button on the console. Once the Work Mode is set, the Heater Unit can work without the console using the pedal.

Maintanance

Before carrying out maintenance or storage, always allow the equipment and the support to cool down.

Check periodically that the Pre Heater and the Support are clean.
Use a damp cloth when cleaning. Alcohol can only be used to clean the metal parts.
Only if it is absolutely necessary and if cleaning with isopropyl alcohol (IPA) is not enough, it is recommended to use a scraper to remove dirt in the glass area.
Replace any defective or damaged parts. Use original JBC spare parts only.
Repairs should only be performed by a JBC authorized technical service.

Safety

It is imperative to follow safety guidelines to prevent electric shock, injury, fire or explosion.

Do not use the units for any purpose other than PCB preheating. Incorrect use may cause a fire.
The mains cable must be plugged into approved bases. Make sure that it is properly grounded before use. When unplugging it, hold the plug, not the wire.
The temperature of accessible surfaces may remain high after the unit is turned off. Handle with care.
Do not leave the appliance unattended when it is on.
Do not cover the ventilation grills. Heat can cause inflammable products to ignite.
Heat can cause inflammable products to ignite even when out of sight.
Be careful with the remains of liquid tin. In contact with the skin, it can cause burns.
Avoid flux coming into contact with skin or eyes to prevent irritation.
Be careful with the smoke produced when soldering.
Keep your workplace clean and tidy. Wear appropriate protection glasses and gloves when working to avoid personal harm.
This appliance can be used by children over the age of eight as well as persons with reduced physical, sensory or mental capabilities or lacking experience provided that they have been given adequate supervision or instruction concerning the use of the appliance and understand the hazards involved. Children must not play with the appliance.
Maintenance must not be carried out by children unless supervised.
