How to select the appropriate splitter according to PCB

The board splitting machine usually refers to the PCB board splitting machine, that is, the substrate board splitting machine. Dividing machine is widely used in electronic product manufacturing industry. When purchasing a splitter, how to select the appropriate splitter according to the PCB?

1、 For the PCB board with components, if the components are not high and the PCB board is not large, it is recommended to choose the knife splitting machine. The utility model has strong universality. When multiple connected PCB boards are welded, they are easy to damage the circuit or break electronic components. The knife splitting machine adopts the method of upper round knife and lower flat knife. When the board is stepped on the lower flat knife, the upper round knife moves laterally to the set point to cut off the PCB board. A transportation platform can also be installed to facilitate the automatic transportation of the cut PCB board, reduce stress and prevent solder joint cracks and part fractures, Improve production efficiency and quality.

2、 For smaller boards, although the design of PCB board is simple, it is recommended to choose the guillotine board machine because it is very thin. The guillotine type plate cutter adopts a new pneumatic electric lightweight design, which can complete the stroke of the plate without shear stress at one time. It is especially suitable for the bow and microcrack produced by the precision SMD or the circular knife type plate without thin plate. The linear plate with wedge-shaped cutter is used to reduce the shear stress.

3、 For irregular PCB boards with stamp holes, it is recommended to choose bridged PCB boards and curve board machines. Curve dividing machine, also known as milling cutter type dividing machine, mainly uses the high-speed operation of milling cutter to divide multi chip PCB according to the pre programmed path, replacing the cutting defects of manual breaking or V-CUT or push. It has high cutting precision, accuracy, long service life, good cutting quality, no dust and burr. It is mainly used to divide irregular PCB board, stamp hole board and connecting board. The cutting stress is less, about 1 / 10 of that of stamping type and 1 / 100 of that of hand breaking, so as to avoid the problems of artificial breaking plate damaged in the cutting process of ceramic capacitor and other chips and tin and parts.
