PCB Dismantling Machine
— Turnkey Precious Metal Refining Plant
PCB component dismantling machines are used to remove electronic components from waste PCBs. Because these components contain various precious metals, some can be sold separately at higher prices. The motherboard after component dismantling is easily broken, and the copper foil is easier to separate. Maximizing profits also reduces the workload of subsequent processes and increases the recovery rate of precious metals.
The main process involves heating the PCB to melt the solder, then separating the PCB motherboard from the electronic components. They are thoroughly separated through rolling friction. During this process, we use filters to treat the exhaust gas. After three stages of treatment, it does not pollute the environment.
Product Overview
A PCB dismantling machine (also known as a circuit board dismantling machine or PCB component dismantling machine) is an automated e-waste recycling machine that separates electronic components from waste printed circuit boards. Its raw materials cover computer motherboards, mobile phone PCBs, TV boards, home appliance boards, automotive boards and PCB scraps — virtually every type of scrap circuit board with precious metal content.
In the process involves heating the PCB board to melt the solder, then separating the PCB motherboard and electronic components. They are thoroughly separated through rolling friction. During this process, the exhaust gas is first adsorbed by activated carbon to remove formaldehyde. Then, water is sprayed to allow the exhaust gas to settle. Finally, we use filters to treat the exhaust gas. This three-stage treatment ensures no environmental pollution.
Three output streams are recovered: tin from the melted solder, electronic components (many loaded with gold, silver and palladium) and clean PCB motherboards — each routed to the most profitable downstream process, from gold stripping to copper electrolysis and precious metal refining.
Recovery Value Analysis
Waste circuit boards are one of the highest-value streams in e-waste, but their value is locked in two very different places: the components and the board itself. Dismantling first unlocks both.
- Components sell at a premium. CPUs, memory chips, gold-plated pins, connectors, MLCC capacitors and other components contain gold, silver, palladium and other precious metals. Sold intact and separately, they command a far better price than when mixed into crushed board powder.
- Boards become easier and cleaner to process. Once components are removed, the bare motherboard is much easier to crush, and copper separation purity improves — raising the efficiency of the downstream PCB recycling machine.
- Tin is recovered as a by-product. The melted solder tin is collected and sold separately instead of being lost in dust or slag.
- No precious metal loss. Gentle, temperature-controlled heating avoids burning components or alloying metals, unlike manual torching or incineration.
Urban-mining context: According to the United Nations Global E-waste Monitor, roughly 62 million tonnes of e-waste were generated in 2022, yet only about 22% was documented as properly recycled. E-waste is far richer in gold than typical gold ore, which is why professional recyclers invest in dismantling and refining lines. On a complete line (dismantling → gold stripping → PCB recycling → copper electrolysis → refining), recovery rates for gold, silver, palladium and copper can exceed 99%.

Process Flow
The complete working process of the PCB dismantling machine:
- Feeding — Waste PCBs are loaded onto the conveyor automatically.
- Heating — The board passes through the heating chamber; the tin solder melts as temperature is automatically controlled.
- Separation — Rolling friction separates the electronic components from the motherboard thoroughly.
- Cooling — Materials are cooled before discharge.
- Output — Components: precious-metal-bearing components go to the gold stripping machine / precious metal refining plant.
- Output — Motherboards: clean boards go to the PCB recycling machine (crushing + electrostatic separation) for metal powder and resin powder, then copper electrolysis.
- Emission Control: exhaust gas passes through activated carbon → water spray → filter (three-level treatment, no pollution).
