PCB dismantling machine

In the e-waste recycling industry, printed circuit boards (PCBs) are the primary target for recovery due to their high volume and substantial resource value. Haoxing Machinery's PCB Dismantling Machine, also known as the Circuit Board Depopulator, PCB Desoldering Machine, or E-Waste Component Stripper, is specifically designed to thermally detach soldered electronic components (capacitors, resistors, IC chips, relays, transformers, etc.) and solder from waste circuit boards. This automated separation yields clean bare boards, intact components, and recovered solder, laying a solid foundation for downstream precious metal extraction and material recycling.

Different electronic components contain various metals—some are rich in gold, silver, and palladium, while others like heat sinks and transformers can be directly sorted and sold. Pre-dismantling with this machine offers significant advantages:

• Preserves Component Integrity: Minimizes damage, facilitating sorting, reuse, or targeted precious metal recovery.

• Efficient Solder Recovery: Detached solder is collected and can be sold directly as a valuable by-product.

• Enhances Bare Board Value: The remaining bare PCB retains its copper foil intact, allowing efficient copper extraction in subsequent crushing and sorting processes, greatly improving overall metal recovery rates.

Haoxing PCB Dismantling Machine achieves fully automated operation encompassing automatic feeding, automatic dismantling, and automatic discharging. The process is as follows:

1. Automatic Feeding & Drum Heating
   Waste circuit boards are conveyed into a perforated stainless steel rotating drum. An electric heating system uniformly raises the internal drum temperature to approximately 150°C - 260°C (adjustable), melting the solder that secures components to the board surface.

2. Drum Rotation & Friction Stripping
   The drum rotates at a controlled speed, causing the PCBs to tumble and rub against each other. The combined effects of gravity, centrifugal force, and mechanical friction cause molten solder and electronic components to naturally detach from the substrate.

3. Automatic Screening & Separation
   The detached solder particles and components slide down the inclined drum into a multi-stage vibrating screen. Using screens with different mesh sizes, fine solder particles pass through to a lower collection bin, while larger electronic components are discharged from the upper outlet. This achieves automatic classification and separate collection of solder and components.

4. Bare Board Discharge & Downstream Processing
   Desoldered bare boards exit the drum's end and are transferred via conveyor to a PCB hammer mill/crusher for further size reduction and copper/fiber separation.

5. Environmental Emission Control
   Organic fumes (flux volatiles) and minimal dust generated during the thermal desoldering process are captured through sealed ductwork. The exhaust is treated by a Spray Tower + Activated Carbon Adsorption system before being safely discharged through a 16-meter exhaust stack, ensuring full compliance with environmental regulations.

1. One-Step Desoldering & Component Removal
   The Haoxing PCB Dismantling Machine completes desoldering and component stripping simultaneously in a single pass. With a robust processing capacity of 400 - 500 kg per hour (depending on board type), it vastly outperforms manual labor.

2. Minimal Component Damage & Precious Metal Loss
   Precise temperature control and gentle tumbling action ensure minimal damage to electronic components, preserving their integrity and the valuable metals they contain, thereby reducing unnecessary precious metal loss during the dismantling phase.

3. Automated Intelligent Control for Safe Operation
   Operating temperature is automatically regulated by the heating system via a PLC touchscreen interface, requiring no manual intervention. The machine is equipped with overheat protection, leakage protection, and emergency stop functions, ensuring simple, safe, and reliable operation.

4. Comprehensive Eco-Friendly Design
   The equipment includes standard dust collection and fume extraction systems (spray tower + activated carbon adsorption) that effectively mitigate environmental pollution, helping operators meet stringent emission standards.

5. Durable Construction & Low Maintenance
   The drum is constructed from high-temperature resistant stainless steel for long service life. The screening mesh is easily replaceable, and overall daily maintenance requirements are minimal, resulting in low operational costs.
