Safety Precautions

Always observe the following safety guidelines to prevent injury and damage to the equipment:

• Ensure the machine is connected to a properly grounded power source (AC220V ±10%, 50Hz).
• Do not operate the machine in damp or wet conditions.
• Wear appropriate personal protective equipment (PPE), such as heat-resistant gloves and safety glasses, when handling hot components.
• Familiarize yourself with the location and operation of the Emergency Stop Button before use.
• Do not attempt to modify or repair the machine unless you are a qualified technician.
• Keep the work area clean and free of flammable materials.
• The machine operates at high temperatures; allow sufficient cooling time before touching heated parts.

Product Overview

The BGA Rework Station S7 is a precision tool for desoldering and soldering BGA, CBGA, CCGA, QFN, CSP, LGA, Micro SMD, MLF, and other IC packages. It features a non-optical design with laser positioning for enhanced accuracy.

Component Identification:

• Upper Heating Head: Provides hot air for the upper temperature zone.
• Upper Air Nozzle: Directs hot air from the upper heating head.
• Lower Air Nozzle: Directs hot air for the lower temperature zone.
• Temperature Measurement Interface: Connects the temperature measurement line for precise monitoring.
• Emergency Stop Button: Immediately cuts power to the machine in emergencies.
• Adjust The Upper Heating Head Up And Down: Knob for vertical adjustment of the upper heating head.
• Adjust The Upper Heating Head Front And Back: Knob for horizontal adjustment of the upper heating head.
• Work Lighting: Illuminates the work area.
• Clamp Fixing Knob: Secures the PCB clamps.
• Drag Plate: Movable platform for positioning the PCB.
• Work Lighting Switch: Turns the work lighting on/off.
• Positioning Red Dot Switch: Activates/deactivates the laser positioning system.
• Height Adjustment In The Second Temperature Zone: Adjusts the height of the infrared preheating zone.
• Start Button: Initiates the rework process.
• Vacuum Suction Pen: Used for safely lifting components after rework.

Setup

Unpacking and Placement:

1. Carefully remove the BGA Rework Station S7 from its packaging.
2. Place the machine on a stable, level, and heat-resistant workbench. Ensure adequate clearance around the machine for ventilation and operation.
3. Inspect all components for any signs of damage during transit.

Connecting Power:

• Connect the power cable to the machine and then to a grounded AC220V ±10%, 50Hz power outlet.
• Ensure the main power switch on the machine is in the "OFF" position before connecting.

Accessory Installation:

The standard configuration includes various nozzles, clamps, and tools. Refer to Figure 4 for identification.

Figure 4: Standard Configuration and Accessories

• Heated Air Nozzles: Select the appropriate size nozzle for your BGA chip and attach it to the upper air nozzle.
• Universal Clamps: Install the universal clamps onto the drag plate to secure the PCB. These clamps are designed to protect the PCB edges and accommodate various BGA package sizes.
• Temperature Measurement Line: Connect the temperature measurement line to the interface for real-time temperature monitoring.
• Vacuum Suction Pen: Connect the vacuum suction pen for safe component removal.

Operating Instructions

Power On and Initial Checks:

1. Turn on the main power switch. The touch screen interface will power on.
2. The system will perform a self-check.

PCB and Component Preparation:

1. Place the PCB onto the drag plate and secure it using the universal clamps.
2. Position the BGA chip to be reworked under the upper heating head.

Laser Positioning:

• Activate the laser positioning system using the "Positioning Red Dot Switch".
• Adjust the PCB or the upper heating head using the adjustment knobs until the laser red dot precisely aligns with the center of the BGA chip. This ensures accurate and fast positioning.

Temperature Profile Setup:

The S7 features three independent heating zones and an instantaneous curve analysis function.

Figure 5: Heating Zones and Curve Analysis

• Upper and Lower Temperature Zones: Heated by hot air. The upper zone can be freely moved, and both can be adjusted up/down.
• Bottom Temperature Zone (IR Preheating): Heated by infrared, with temperature precisely controlled within ±2°C. The output power can be adjusted.
• Use the touch screen interface to select or create a temperature curve profile suitable for your BGA chip and solder type. The system can store multiple profiles and offers password protection.
• During operation, temperature data is displayed in real-time as a curve on the touch screen.

Rework Process:

1. Once the temperature profile is set and the chip is positioned, press the "Start Button" to begin the rework cycle.
2. Monitor the temperature curve on the screen.
3. Once the solder reflows, use the vacuum suction pen to carefully lift the BGA chip.
4. Allow the PCB and surrounding components to cool down naturally or with controlled cooling if specified by the profile.

Maintenance

• Cleaning: Regularly clean the work area, nozzles, and clamps to prevent solder residue buildup. Use a soft, dry cloth for the touch screen.
• Nozzle Inspection: Periodically check the heated air nozzles for blockages or damage. Replace if necessary.
• Temperature Sensor: Ensure the temperature measurement line is clean and properly connected for accurate readings.
• General Inspection: Before each use, visually inspect the machine for any loose connections, damaged cables, or unusual wear.
• Storage: When not in use, store the machine in a clean, dry environment, protected from dust and extreme temperatures.

Troubleshooting

Specifications

User Tips

• Practice First: If you are new to BGA rework, practice on scrap boards before attempting repairs on valuable devices.
• Temperature Profiles: Experiment with different temperature profiles to find the optimal settings for various solder types and chip packages. Document your successful profiles.
• Preheating: Utilize the IR preheating zone effectively to minimize thermal stress on the PCB and components, ensuring a more uniform heating process.
• Component Removal: Use the vacuum suction pen immediately after the solder reflows to prevent components from shifting or re-soldering incorrectly.
• Post-Rework Cleaning: After rework, thoroughly clean the PCB to remove any flux residue, which can cause short circuits or corrosion over time.
