When large quantities of waste circuit boards need to be processed, manually removing electronic components can take considerable time and labor. Our PCB dismantling machine provides a mechanical solution for removing solder and electronic components from discarded PCB boards, preparing the boards and recovered components for further recycling.
The machine is mainly used as a pretreatment step in a PCB recycling line. After dismantling, the recovered PCB substrates, tin, and electronic components can be separately collected and sent to suitable downstream recycling processes.
What Can the PCB Dismantling Machine Process?
This PCB boards dismantling machine is designed for waste circuit boards collected from different electrical and electronic equipment. Typical materials include circuit boards from discarded household appliances, computers, electronic equipment, and other waste electrical and electronic equipment.
The main purpose is not simply to break the PCB into pieces, but to first remove the electronic components and solder attached to the board. This makes it easier to handle the remaining PCB material in the following recycling stages.
How Does the PCB Dismantling Process Work?
The dismantling process combines heating and mechanical separation.
First, waste PCB boards enter the heating section. The solder connecting the components to the circuit board is heated and softened. The treated boards are then transferred to the automatic dismantling section.
Mechanical action removes the loosened electronic components from the PCB substrate. During operation, the dust exhaust and collection system can collect dust generated during the dismantling process.
After separation, the main materials are collected separately:
Waste PCB Boards → Heating/Tin Removal → Mechanical Dismantling → PCB Substrates + Tin + Electronic Components
The separated materials can then be further sorted or processed according to their recycling value.
What Are the Main Components of a PCB Dismantling Machine?
Depending on the customer’s processing requirements, the PCB electronic component dismantling system can consist of:
- Tin removal furnace
- Automatic dismantling machine
- Conveyor platform
- Dismantling chamber
- Automatic dust exhaust system
- Dust collection system
- Electrical control system
The integrated configuration helps connect the heating, dismantling, conveying, and dust collection processes into one working system.
Two Important Functions in PCB Dismantling
Tin Removal
Heating is an important part of the dismantling process. By heating the solder on the PCB, the connection between the electronic components and the board can be loosened, creating better conditions for mechanical separation.
The machine has an adjustable temperature range of 25–300°C and uses an automatic temperature control system.
Electronic Component Removal
After the solder has been heated, the automatic dismantling mechanism removes electronic components from the PCB board. This reduces the amount of manual work required compared with traditional hand dismantling.
The recovered components can be collected for further sorting, while the remaining PCB substrates can continue to the next recycling stage.
High-Temperature Dismantling Machine Structure
The high-temperature section uses a 6 mm thick No. 45 steel plate for the inner cylinder. Insulation cotton is installed on the outer wall to reduce heat loss during heating.
The heating system incorporates automatic temperature control and forced air supply. The set temperature can also be memorized automatically, which is convenient when processing similar materials repeatedly.
This structure is designed for stable operation during continuous PCB dismantling work.
Technical Parameters of Our PCB Dismantling Machine
| 模型 | Temperature Range | Rotary Speed | 力量 | 容量 |
| 80-90# | 25–300°C | 5–60 r/min | 2.2 + 1.1 kW + 12 kW electric heating | 300–400 kg/h |
| 90-100# | 25–300°C | 5–60 r/min | 2.2 + 1.1 kW + 12 kW electric heating | 400–500 kg/h |
The actual processing capacity can vary depending on PCB type, size, solder content, and feeding conditions.
Materials Recovered After Dismantling
A major advantage of using a PCB dismantling machine before further processing is that the different components of waste circuit boards can be separated at an early stage.
PCB Substrate
After the electronic components are removed, the remaining PCB boards can be sent to crushing and separation equipment for further material recovery.
Tin and Solder
The removed solder and tin can be collected separately for subsequent recycling.
Electronic Components
Electronic components removed from the boards can be collected and sorted according to their type and material.
This gives customers several material streams instead of sending the entire PCB directly into a crushing process.
PCB Dismantling Machine as Pretreatment Equipment
For a complete waste PCB recycling project, dismantling is usually only the first stage. After the electronic components and solder have been removed, the remaining PCB boards can be further processed by crushing and separation equipment.
For example, a recycling system may include:
Waste PCB → PCB Dismantling Machine → Crushing → Screening → Material Separation → Recovered Materials
We can also provide other recycling equipment according to the material and final product requirements, including metal shredders, metal crushing machines, density separators, and electrostatic separators.
The equipment configuration can therefore be adjusted according to the customer’s raw materials, required capacity, and desired recycling products.
Why Use a PCB Boards Dismantling Machine?
For recycling companies handling a steady supply of waste circuit boards, manual component removal can become a bottleneck. A mechanical dismantling system offers a more efficient way to prepare PCB boards for further processing.
Key advantages include:
- Mechanical removal of electronic components
- Automatic heating and temperature control
- Reduced manual dismantling work
- Separate collection of PCB substrates, tin, and components
- Dust exhaust and collection system
- Suitable for integration into PCB recycling projects
- Compact equipment configuration
- Processing capacity up to 400–500 kg/h for the listed models
Choose the Right PCB Dismantling Solution
Different waste PCB boards can contain different types and quantities of electronic components and solder. Therefore, the suitable PCB Dismantling Machine should be selected according to the customer’s raw materials and required capacity.
If you are planning a waste PCB recycling project, you can send us photos or videos of your PCB boards together with your expected processing capacity. Our team can recommend a suitable dismantling and subsequent recycling equipment configuration for your project.
