PCB connecting design refers to the process of connecting multiple PCBs together through certain pipes to form an overall structure. This design pipeline is usually used to solve problems such as insufficient layout space on a single PCB board, high system complexity, and long signal transmission distances. Through the board-connected design, each functional module can be distributed on different PCB boards, thereby achieving more efficient and stable system operation.
When we are processing PCBA boards, some PCB boards are relatively small in size. For production efficiency, they need to be made into pipes connecting the boards. After completing the PCBA processing, the PCBA boards need to be divided into boards. Then during the deboarding process, you need to pay attention to some precautions to prevent damage to the intact PCBA board.
When manually dividing the board, you need to pay attention to the fact that when folding the edge, you must hold the lower edge of the PCBA board with both hands, less than 20mm away from the V-cut, and try to avoid bending deformation, damage to the PCBA power circuit, components, and tin channels.
Requirements for machine PCBA subboarding:
1. Stable support point. Without support, the stress generated may damage the substrate and welding points. Distorting the board, or stressing the assembly during depaneling, can cause hidden or obvious defects.
2. Wear protective tools and make protective preparations before operating. It is necessary to install high-frequency eye protection lighting devices to protect the safety of operators. It is best to bring a pair of glasses to protect your eyes.
3. Frequently wipe the machine spindle and cutting tools with alcohol to remove PCB board dust generated during the de-boarding process and maintain the normal operation of the de-boarding machine.
4. After using it a certain number of times, oil and lubricate the sliding rods and bearings of the splitter and check whether there are loose screws, etc.
5. During the use of the machine, the work surface should be kept clean, and it is best not to place other things to prevent things from falling on the cutter and causing damage to the cutter and items. Although there is an electric eye for protection, you still need to pay attention to maintaining a certain safe distance between your fingers and the tool during use.
When PCBA is depaneled, machine depaneling is more efficient than manual depanning, with high efficiency and low damage rate. However, when performing machine splitting, the process must be strictly followed to reduce human errors.
