Core operational workflow of circuit board component disassembly machine

As market demand for high-end microchips and power modules continues to soar, the focus of PCB (Printed Circuit Board) recycling has shifted from mere “shredding for copper recovery” to “disassembly, recovery, and reuse.” As the initial stage of electronic waste processing, the primary function of a circuit board disassembly machine is to non-destructively separate electronic components—such as capacitors, chips, and resistors—from the mainboard substrate.

The core operational workflow of SUNYGROUP’s circuit board disassembly machine are as follows:

Feeding and Preheating: Waste circuit boards enter a rotating drum equipped with internal screens. Inside the drum, an electric heating system raises the temperature to approximately 150–250°C, causing the solder to melt.

Rotary Disassembly: The friction and vibration generated by the rotating drum cause the electronic components to detach from the circuit board substrate, allowing them—along with the molten solder—to fall away.

Sorting and Collection: The separated electronic components and solder residue pass through the screens into a sorting mechanism, where they are separated from the remaining circuit board fragments.

Environmental Treatment: The equipment is outfitted with a smoke filtration and exhaust gas treatment system to process the fumes and toxic gases generated during disassembly, ensuring compliance with environmental emission standards.

Utilizing an automated control system, the circuit board component disassembly machine achieves highly efficient operation by automatically executing the heating, disassembly, and cooling stages. This significantly boosts production efficiency while simultaneously reducing the complexity and cost associated with manual labor. Furthermore, the integration of a smoke filtration system and exhaust gas treatment unit effectively mitigates the release of harmful gases generated during the disassembly process, thereby ensuring a safe and environmentally compliant working environment that meets modern industrial standards.
