Haoxing Machinery's PCB Dismantling Machine, also called a circuit board depopulator or PCB desoldering machine, is used to remove electronic components and solder from waste printed circuit boards. It is suitable for processing waste PCBs from computers, televisions, mobile phones, communication equipment, household appliances and other electronic products.
The machine uses controlled heating and rotating drum movement to separate electronic components from the PCB surface. During operation, the circuit boards are heated inside the drum, and the solder softens or melts. As the drum rotates, components and solder particles gradually detach from the board and enter the screening and collection section.
After dismantling, the separated components, solder particles and bare PCB boards can be collected for further sorting or downstream recycling. Bare boards can be sent to PCB crushing and separation equipment for copper and fiber recovery according to the recycling process.
The PCB dismantling machine can be equipped with feeding system, heating drum, screening system, discharge system, exhaust treatment, dust collection and electric control cabinet. The configuration can be selected according to PCB type, required capacity, site layout and environmental treatment requirements.

The Haoxing PCB dismantling machine is designed to remove electronic components and solder from waste printed circuit boards. It uses controlled heating, drum rotation and screening to separate electronic components, solder particles and bare PCB boards for further recycling.
Waste circuit boards are fed into a perforated stainless steel rotating drum by a conveyor or feeding device. The electric heating system raises the drum temperature to the required operating range, helping soften or melt the solder that holds electronic components on the board surface. The temperature can be adjusted according to the PCB type, component density and processing requirements.
During operation, the drum rotates at a controlled speed. The circuit boards tumble and rub against each other inside the heated drum. Under the combined action of heat, gravity and mechanical friction, electronic components and solder gradually detach from the PCB substrate.
The separated solder particles and electronic components enter the screening section. Different screen openings can be used to classify fine solder particles and larger electronic components. The separated materials are discharged through different outlets for collection and further processing.
After component removal, the bare PCB boards are discharged from the end of the drum. Depending on the recycling process, the bare boards can be sent to a PCB crusher, pulverizer, electrostatic separator or other downstream equipment for copper and non-metallic material separation.
During thermal dismantling, fume extraction and dust collection equipment can be configured according to the material condition and site requirements. The exhaust treatment system can include a spray tower, activated carbon adsorption unit or other treatment equipment according to the project configuration.
Component and solder separation: The PCB dismantling machine is used to remove electronic components and solder from waste circuit boards. It can separate components, solder particles and bare PCB boards for further sorting or downstream recycling.
Controlled heating system: The machine uses an electric heating system with adjustable temperature control. The working temperature can be set according to PCB type, solder condition, component density and processing requirement.
Rotating drum structure: The perforated stainless steel drum rotates at a controlled speed. During operation, the heated PCB boards tumble and rub inside the drum, helping electronic components detach from the board surface.
Screening and material collection: After dismantling, solder particles, electronic components and bare boards can be discharged and collected separately. Screening equipment can be selected according to material size and sorting requirement.
PLC control system: The machine can be equipped with PLC control for temperature adjustment, drum rotation, feeding, discharging and system operation. Emergency stop, overheating protection and leakage protection can also be configured according to equipment design.
Exhaust and dust collection available: Fume extraction, dust collection, spray tower, activated carbon adsorption and other exhaust treatment equipment can be configured according to material condition and site requirements.
Suitable for PCB recycling lines: The machine can be used as a pre-treatment unit before PCB crushing, copper recovery, electrostatic separation or other downstream recycling processes.
Custom configuration available: Feeding method, drum size, heating power, temperature range, screening structure, discharge method, exhaust treatment and control system can be customized according to PCB type, capacity requirement and site layout.

Find common questions about scrap metal crushers, shredders, recycling lines, equipment selection, capacity configuration and operation requirements.
The model mainly depends on your circuit board type, board size, daily processing capacity, and recycling process layout. If you are building a complete PCB recycling line, it is better to choose the machine together with crushing, sorting, and dust collection equipment to match the whole production capacity.
Before operation, waste circuit boards should be sorted as much as possible and large impurities should be removed. The machine should be placed on a stable floor, and operators should check the power connection, heating system, conveyor, and discharge area before starting. Proper preparation helps the machine run more smoothly.
Yes. By removing electronic components before crushing and separation, the PCB dismantling machine helps reduce mixed materials and makes the following recycling process more efficient. It is useful for improving the recovery of copper, aluminum, tin, and other valuable materials from waste circuit boards.
A PCB dismantling machine is suitable for many kinds of waste circuit boards, such as computer boards, TV boards, appliance control boards, communication boards, and mixed electronic circuit boards. The actual processing result may vary depending on the board size, component type, and material condition.
Yes. A PCB dismantling machine can be used to remove electronic components from waste circuit boards and improve the efficiency of later crushing, separation, and metal recovery.
