PCB Cutting Board Process and Precautions
The process of PCB board cutting is as follows:
Prepare Tools and Materials: Prepare suitable tools for cutting boards, such as cutters, saws, blades, etc., as well as the necessary protective equipment, such as gloves, goggles, etc.. At the same time, prepare the necessary fixtures and support brackets and other auxiliary tools.
Inspection of PCB Substrate: Before cutting the board, it is necessary to inspect the PCB substrate to ensure that its surface is free of scratches, stains and other problems, and check the size, shape and specifications of the substrate and other information to ensure that it meets the design requirements.
Placement of Fixtures and Support Frames: According to the shape and size to be cut, the corresponding fixtures and support frames are placed on the board cutting machine or working table to ensure stability and safety.
Positioning and Fixing the PCB Substrate: Place the qualified PCB substrate on the fixture and support frame to ensure that it is correctly positioned and firmly fixed to prevent it from moving or tipping over during the cutting process.
Cutting: According to the shape and size to be cut, use the board cutting tool to cut. In the process of cutting, we need to pay attention to the operation safety, to avoid the cutter or blade to personnel injury. At the same time, you need to pay attention to the quality of the cut to ensure that the edges are neat and smooth.
Inspection and Finishing: After the cutting is completed, the cut PCB needs to be inspected to ensure that the edges are neat and free of burrs and other problems. At the same time, the cut PCB should be organized, classified and well marked.
In the cutting process, you need to pay attention to safety issues, comply with operating procedures and safety standards to avoid injury.
Before cutting, you need to carefully check the size, shape and specifications of the PCB substrate information to ensure compliance with the design requirements.
In the cutting process, you need to pay attention to the quality of the cut to ensure that the edges are neat and smooth. If necessary, it can be buffed.
The cut PCB needs to be stored properly to avoid moisture, pollution and other problems to ensure its quality and reliability.
There are different characteristics and applicable range, and should be selected by considering the requirements of efficiency and precision.
Consider the Hardness and Thickness of the Material: When cutting materials of different hardness and thickness, appropriate tools and cutting parameters should be selected. Harder materials may require sharper blades and higher cutting speeds, and thicker materials may require deeper cutting depths and slower cutting speeds.
Keep Clean and Tidy: During the cutting process, the work area should be kept clean and tidy to avoid dust, dirt and other impurities from affecting the quality of the cut. Meanwhile, blades or saw blades should be checked and replaced regularly to ensure that they are sharp and clean.
Consider the Thermal Expansion Coefficient of The Material: When cutting PCB substrates of different materials, the impact of the thermal expansion coefficient of different materials on the cutting accuracy should be considered. Special attention should be paid to the thermal expansion of the material when cutting in a high temperature environment.
Follow the Environmental Requirements: In the cutting process, we should follow the environmental requirements and reasonably dispose of the waste and trimmings to reduce the pollution to the environment.
Record and Track: In the cutting process, each cut PCB should be recorded and tracked, including size, quantity, quality and other information. This helps in subsequent tracing and quality control.
Preventive Measures: During the cutting process, attention should be paid to preventive measures, such as wearing gloves, goggles and other protective equipment to reduce the risk of accidental injury. At the same time, the operating condition of the equipment should be checked regularly to ensure that it is safe and reliable.
