The WHA3000V will perform demanding repair tasks on circuit boards with complex fine pitch surface mounted components.
The advanced control technology coupled with user friendly operation, guarantees process control. The sophisticated automatic operation mode guarantees repeatability of the process and increases productivity and quality.
Extensive range accessories compliment the machine to promote flexibility.
A digital electronic control system guarantees precise temperature control and provides other functions, such as Auto off and stand by temperature. Set and actual temperatures are displayed digitally. Two heated zones can be selected The temperature of a specific point on the board under repair can be monitored and controlled by means of an optional external sensor. If used the temperature display will show the actual value of the temperature of the board at the point of contact, not the temperature of the hot plate elements. An RS232 interface connection from either of the WHA stations can be used to enable the hot plate to be used as an underside heater in a multilevel process sequence. If this option is required then we recommend that the WBH3000 board holder is used. The pre-heating plate is designed to sit between the side supports of the board holder.
LCD Display:
High contrast LCD characters clearly display the operating parameters.
Manual operation Operating parameters are selected by the operator.
Automatic mode A three-stage temperature/time profile controlling air temperature, air volume and process time can be stored in the machine memory to carry out repeatable repair operations. The WHP3000 hot plate can also be controlled in this mode. Up to 10 individual programs can be stored in the machines memory.
Both the WHA3000P and WHA3000V include a two-stage foot switch. Stage 1 activates the hot air flow, stage 2 activates the vacuum pickup. Additional Product Features and Benefits:
- Setting Up down push buttons set the operating parameters of the air temperature, air volume and process time. LED indicators highlight the operating mode, start/ stop and vacuum functions.
- Hot air pencil The ergonomic and powerful hot air pencil (700 W) together with the extensive range of patented technology nozzles make this tool very versatile. Hot air nozzles are secured to the tool by a clamping screw. A vacuum plate will lift the component from the board after reflow.
A nozzle removal tool supplied with the machine enables rapid removal and replacement of nozzles, even when hot.
- ESD safe The hot air is delivered through an ion trap to remove any charge and the tool handle and tubing are manufactured from static dissipative materials.
- Air generation The airflow rate is controlled digitally by means of a proportional valve. Alternatively, an inert gas, such as nitrogen could be used in place of compressed air for more demanding tasks.
- Connections The rear of the machine has an RS232 interface for connection to the WHP3000 pre-heat plate or a PC for remote control. Socket for manual control or foot pedal.
Compressed air / inert gas 4 – 6 bar.
- Temperature check Connection of the temperature sensor (available as an accessory) for highly accurate process monitoring.
