Principle and Classification of PCB Splitter

Principle and Classification of PCB Splitter

When PCB boards are divided, they are traditionally divided manually. This method has a relatively fast time effect. However, due to the difference in force and separation angle, it is easy to cause damage to PCB electrical circuits, parts and tin tracks. At this time, PCB board splitter came into being and became the SMT standard operation mode.

1、 Principle of PCB Splitter

1. Before board splitting, first confirm whether the board splitting program edited by the engineer is correct. When the engineer edits or calls out the program used before, first conduct a preview check. After the left and right workbench programs are checked to be correct, let the engineer process one piece on the left and right respectively for confirmation, and then the operator can operate by himself after confirmation.

2. Put the PCB board to be punched into the fixture, distinguish the direction of the board and the front and back sides, put the fixture, and place the board on the positioning column of the positioning fixture, gently press with your hand to confirm whether it is in place, then press the left or right green button under the cover of the panel dividing fixture, and the workbench automatically enters the panel dividing position.

3. Click the preview button of the software, the button is red, and observe whether each cutting position is correct. After viewing and checking, click the stop button on the software first. After a few seconds, the color turns green and automatically changes to the processing button, and the workbench automatically exits. Click the processing button on the software to start the processing.

2、 Classification of PCB splitters

According to the plate material, it can be divided into three categories: PCB plate splitter, FPC plate splitter and aluminum substrate plate splitter. According to the different plate splitting methods, it can be divided into: 1. knife type plate splitter, 2. punch type plate splitter, 3. milling type plate splitter, 4. laser plate splitter, 5. cutter type plate splitter.

3、 Advantages and Disadvantages of Various Board Splitters

1. Advantages of the knife type plate splitter: low cost Disadvantage: it can only perform linear plate division. There are burrs.

2. Advantages of stamping type plate splitter: low cost and fast speed for the first time. Disadvantages: Due to the need for special plates and molds, the cost is high in the later period. Stressed

3. Advantages of milling cutter type plate splitter: it can divide plates of any shape, with very low stress and no rough edges at the cutting edge. Disadvantages: The first time cost is high.

4. Advantages of laser board splitter: It also has the advantages of a milling cutter board splitter, and can perform differential cutting of PCB boards without stress. Disadvantages: The machine is expensive.

5. The advantages of the guillotine type plate splitter: pure pneumatic (air pressure commonly used in the factory), small size (desktop type), large output, can cut aluminum substrates of any width and thickness, with high cost performance.

PCB splitter has been widely used in the electronic product manufacturing industry. PCB splitter has good performance, which can reduce the damage to PCB as much as possible in the process of splitting, and ensure the initial quality of PCB.

PCB manufacturers and PCB designers will explain the principle and classification of PCB splitters.
