Waste circuit boards contain different materials, including PCB substrates, solder, and various electronic components. Before the boards enter a crushing and separation process, removing the attached components can make the subsequent recycling process easier to arrange. Our PCB dismantling machine is designed for this pretreatment stage, helping separate electronic components and solder from discarded circuit boards.
The machine is suitable for circuit boards collected from waste household appliances, computers, and other electronic equipment. After dismantling, the separated materials can be collected individually for further recycling and sorting.
A Practical Solution for Waste PCB Pretreatment
The main purpose of the PCB dismantling machine is to remove electronic components and solder from waste PCB boards rather than directly crush the entire board.
The process mainly consists of two steps: heating and mechanical dismantling.
During heating, the solder connecting the electronic components to the PCB substrate is softened. The boards are then transferred to the dismantling section, where mechanical action helps remove the loosened components.
This arrangement reduces the need for manual component removal and provides a more consistent pretreatment process for waste PCB recycling.
What Materials Can Be Separated?
After the PCB dismantling process, three main material streams can be obtained:
PCB substrate
The remaining circuit boards can be collected and sent to subsequent crushing and separation equipment.
Tin and solder
The solder removed during the heating and dismantling process can be collected separately for further treatment.
Electronic components
Components removed from the PCB boards can be collected and sorted according to their type and material.
This initial separation allows these materials to be handled separately instead of processing the entire PCB together from the beginning.
How the PCB Dismantling Machine Works
The working process can be arranged as follows:
Waste PCB Boards → Heating → Solder Softening → Mechanical Dismantling → Material Collection
Heating the PCB Boards
The waste circuit boards first enter the heating section. The solder on the boards is heated within the required temperature range, helping loosen the connection between the components and the PCB substrate.
The machine is equipped with automatic temperature control, with a working temperature range of 25–300°C.
Mechanical Component Removal
Once the solder has been softened, the circuit boards enter the automatic dismantling section. Mechanical action separates the electronic components from the PCB substrate.
This process is designed to reduce manual dismantling work and improve processing efficiency.
Separate Material Collection
The dismantled materials are discharged and collected for further processing. PCB substrates, electronic components, and tin can be handled separately according to the customer’s recycling requirements.
Main Components of the PCB Dismantling System
A complete PCB electronic component dismantling system can be configured with several functional units:
- Tin removal furnace
- Automatic dismantling machine
- Conveyor platform
- Dismantling chamber
- Automatic dust exhaust system
- Dust collection system
- Electrical control system
The conveyor platform connects the different sections, while the electrical control system manages the main operating functions.
The dust exhaust and collection system is also incorporated into the equipment configuration to collect dust generated during dismantling.
High-Temperature Dismantling Section
The high-temperature dismantling section is designed with a reinforced inner cylinder made from 6 mm thick No. 45 steel plate.
Insulation cotton is installed on the outer wall to help reduce heat loss during operation. The heating system uses automatic temperature control and forced air supply.
The set temperature can be memorized automatically, which is convenient when processing similar PCB materials repeatedly.
Technical Data of Our PCB Dismantling Machine
For customers looking for different processing capacities, the available models include:
| Model | Temperature Range | Rotary Speed | Power | Capacity |
| 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 |
Actual output may vary depending on the type, size, composition, and feeding conditions of the waste PCB boards.
Suitable Waste PCB Applications
The PCB dismantling machine can be used for dismantling circuit boards from various discarded electrical and electronic products, including:
- Waste household appliance PCBs
- Computer circuit boards
- Motherboards
- Electronic equipment circuit boards
- Scrap printed circuit boards
- Other waste electrical and electronic equipment
Before selecting the PCB dismantling machine, the customer’s actual PCB material can be checked to determine the suitable equipment configuration.
Used Before Further PCB Recycling
The PCB dismantling machine is mainly used as a pretreatment machine rather than a complete PCB recycling system.
After electronic components and solder have been removed, the remaining PCB substrates can enter the next processing stage.
A typical process can be arranged as:
Waste PCB → Dismantling → PCB Crushing → Screening → Separation → Recovered Materials
For the subsequent recycling process, we can also provide metal shredders, metal crushing machines, density separators, electrostatic separators, and other related equipment according to the material characteristics and required final products.
This allows the dismantling machine to be incorporated into a larger PCB recycling project instead of operating as an isolated piece of equipment.
What to Consider Before Buying a PCB Dismantling Machine?
The type of waste PCB is an important factor when selecting PCB component dismantling machine. Different circuit boards may have different sizes, solder quantities, component types, and structures.
Processing capacity is another key consideration. Customers should determine the expected amount of PCB material to be handled per hour before choosing a model.
It is also important to consider what materials need to be recovered after dismantling. If the project requires further separation of the PCB substrates, additional crushing and sorting equipment may be required.
