ATTEN ST-862D Hot Air Rework Station
The ATTEN ST-862D is a professional hot air rework station designed for precise and efficient desoldering and rework tasks on SMD components. This station is engineered to provide reliable performance and user-friendly operation, making it suitable for both experienced technicians and those new to SMD rework.
Function Description:
The primary function of the ST-862D is to deliver a controlled stream of hot air for the removal and placement of surface-mount devices. It features a powerful heating element and a precise air pump to generate temperatures ranging from 100°C to 480°C and adjustable airflow from 10% to 99%. The station incorporates a sophisticated control system that ensures stable temperature and airflow, crucial for delicate rework operations. It also includes a standby heater cooling function, which automatically cools down the heating element when the hot air gun is placed in its holder, extending the life of the heating wire and ensuring safety.
The device is equipped with a clear LCD display that shows real-time temperature, set temperature, actual temperature value, heating power status (represented by dynamic bars), and air flow percentage. A lock symbol indicates when the temperature setting is secured, preventing accidental changes during operation. The unit also features a beep alarm function to alert users to various operational statuses or errors.
Safety is a key aspect of the ST-862D's design. It includes multiple abnormal detection features, such as heating element removal detection, heating element open circuit detection, heating element overheating detection, and temperature sensor open circuit detection. These features help prevent damage to the equipment and ensure user safety. The station is designed for use with genuine ATTEN parts and accessories to maintain optimal performance and safety standards.
Usage Features:
The ST-862D offers intuitive controls and several features to enhance usability and efficiency.
- Temperature and Airflow Adjustment: Users can easily adjust both temperature and airflow using dedicated "plus" and "minus" keys. Long pressing these keys allows for rapid adjustment, and settings are automatically saved after a few seconds of inactivity. The temperature can be set in either Celsius or Fahrenheit.
- Shortcut Keys: Three shortcut keys (1, 2, 3) are available for quickly retrieving or saving user-defined temperature and airflow settings. This allows for rapid switching between frequently used profiles, streamlining repetitive tasks. To save a setting, the user simply presses and holds the desired shortcut key for more than 3 seconds.
- Menu Mode: The station features a menu mode for accessing advanced settings. This mode is entered by pressing buttons "1" and "3" simultaneously for more than 3 seconds. Within the menu, users can navigate through different options using "1" (page up) and "3" (page down) buttons, and confirm selections or exit using button "2".
- Temperature Locking Function: A "Menu Loc" option allows users to turn on or off the temperature locking function. When activated, the temperature setting cannot be accidentally adjusted, providing consistency during critical rework.
- Defining Work Function (HTO Mode): The "HTO" menu allows users to set a specific time for defining work, ranging from 10 to 900 seconds. Setting it to "0" turns off this function. This feature can be useful for timed operations or for ensuring consistent heating durations.
- Temperature Unit Switching: Users can easily switch between Celsius (°C) and Fahrenheit (°F) temperature units via the "C-F" menu.
- Temperature Calibration: The "CAL" menu provides a temperature calibration function, allowing users to fine-tune the displayed temperature to match actual measurements. This is particularly useful after replacing heating elements or nozzles to ensure accuracy. The calibration range is ±50°C (±90°F).
- Button Beeping Function: The "BL" menu allows users to enable or disable the beeping sound that accompanies button presses, offering customization for user preference.
- Auto-Standby and Auto-Sleep: When the hot air gun is placed in its holder, it automatically enters a standby mode, stopping heating and initiating a cooling process for the heating wire. Picking up the handle and pressing the switch key resumes operation. This feature conserves energy and extends component lifespan.
- Boot-up Screen: Upon power-on, the display briefly shows the system version number before switching to the normal operating display, providing quick system information.
Maintenance Features:
The ATTEN ST-862D is designed with maintenance in mind, incorporating features that facilitate troubleshooting and ensure longevity.
- Abnormal Detection and Fault Codes: The station continuously monitors its internal components for abnormal conditions. If a fault is detected, a specific error code (e.g., E2 for open circuit of sensor, E3 for no zero-cross signal, E7 for short circuit of sensor, E8 for over-temperature protection) is displayed, helping users quickly identify the problem.
- Troubleshooting Guide: The manual provides a clear guide for interpreting fault codes and their likely causes, such as poor contact of the air gun connector, damaged zero-cross sensor, or issues with the heating core. This empowers users to perform basic troubleshooting and maintenance.
- Heating Core Replacement: In cases of heating core issues (e.g., short circuit or over-temperature), the system prompts the user to replace the heating core, a common maintenance task for hot air stations.
- Interference Detection: If the display shows "messy code," it suggests strong external interference or an internal circuit abnormality. The manual advises changing the operating environment or seeking professional maintenance in such cases.
- Factory Reset: The "FAC" menu allows users to restore the station to its default factory settings, which can be useful for resolving configuration issues or preparing the device for a new user. This reset includes default values for temperature lock, calibration, beeping function, temperature unit, timing operation, and memory temperatures.
- Use of Original Accessories: The manual strongly emphasizes using original ATTEN accessories and parts for replacement. This ensures compatibility, maintains the product's warranty, and guarantees optimal performance and safety.
- Power-off for Maintenance: Users are instructed to turn off the power when replacing parts or iron tips and to wait until the equipment has completely cooled down before resuming use, preventing burns and ensuring safety during maintenance.
- Regular Cleaning and Care: While not explicitly detailed as a feature, the general advice for electronic equipment maintenance applies, such as keeping the product away from flammable materials and out of reach of children, and avoiding use in wet environments.
The ATTEN ST-862D is a robust and feature-rich hot air rework station that combines powerful performance with user-centric design and comprehensive safety and maintenance provisions.
