Due to the relatively small size of some PCB boards, they are often made into a splicing method. After the PCBA assembly processing is completed, the PCBA splicing boards need to be separated. The separation method is mainly divided into manual boarding and machine boarding. During the boarding process, some precautions should be paid to prevent damage to the intact PCBA board.
Requirements for manual sub-board
1. When folding the edge of the board, you must hold the lower edge of the PCBA board with both hands, and avoid bending deformation, PCBA electrical circuits and parts, and tin channels.

Requirements for machine sub-board
1. Stable support point
Without support, the resulting stress may damage the substrate and solder joints. Distorting the board, or stressing the assembly during board splitting, can cause hidden or obvious defects.

2. Wear protective gear
Before operating, you must be prepared for protection, and you need to install high-frequency eye-protection lighting devices to protect the safety of operators. It is best to bring a pair of eyes to protect your eyes.

3. Use alcohol to wipe the machine spindle and cutters frequently to remove PCB dust generated during the boarding process and maintain the normal operation of the boarding machine.

4. After using a certain number of times, lubricate the sliding rods and bearings of the splitter and check whether the screws are loose.

5. In the process of using the machine, the work surface should be kept clean, and it is best not to place other things to avoid damage to the tools and objects caused by things falling on the tools. Although there are electric eyes for maintenance, it is still necessary to pay attention to a certain safe distance between the fingers and the tool during use.

In general, when PCBA splits the board, the use of machine splitting is more important than manual splitting, with high efficiency and low damage rate. However, when the machine splits the board, it must be operated strictly in accordance with the process to reduce human errors.
