Application of deep analysis milling cutter PCBA dividing machine in stamp hole circuit board technology

With the continuous development of the whole electronic industry, many products in the electronic industry have perfect upstream and downstream supporting enterprises. From the scheme design, appearance design, processing and manufacturing, assembly and testing, packaging, wholesaler channels of a mature product, such an industrial chain is naturally generated in a specific environment. Therefore, the relationship between design and manufacturing is extremely close and inseparable.

One of the more important links from the completion of electronic product design to processing and manufacturing is the processing of PCB circuit board. Most of the bare boards processed by PCB are assembled by the mounter.

Then the problem comes. Now electronic products are developing towards miniaturization and portability. When your design PCB board is very small, and some electronic product modules are as small as a few centimeters square, PCB processing and manufacturing is easy to say, but when it comes to PCB assembly, such a small area is put on the mounter for assembly, which brings problems. There is no way to go to the assembly line!

PCB (printed circuit board), also known as printed circuit board, printed circuit board, circuit board, PCB circuit board, etc., is an important electronic component, the support of electronic components and the provider of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board.

PCB assembly is mainly to make full use of the plate, so as to improve the production efficiency. Usually, after the PCB of the panel is welded, the PCB of each function should be cut. This process evolves into a full-automatic panel splitting process of manual segmentation - V-CUT slot panel splitting machine segmentation - full-automatic milling cutter PCBA panel splitting machine - on-line full-automatic vision PCB panel splitting machine transformation and upgrading.

Classification, advantages and disadvantages of PCBA splitter:

Now the board splitter usually refers to the PCB board splitter, that is, the circuit board splitter. Dividing machine is widely used in electronic product manufacturing industry. Because the traditional manual folding method will produce strong stress and seriously affect the product quality, the manual folding has been basically replaced by machine splitting.

Sub board machine

V-CUT slot circuit board cutting is to cut a V-shaped straight-line shallow slot on both sides at the position where the circuit board needs to be divided.

Advantages: simple equipment, high speed and low cost.

Disadvantages: only square panels can be processed, and multiple panels cannot be processed at the same time. There are strict accuracy requirements for the depth of V-groove, and the dimensional accuracy of V-CUT panels is low. The connection interface is rough after splicing and splitting.

The stamp hole circuit board Gong board is to use the milling cutter PCB plate dividing gong machine to produce the specified panel pattern through the milling cutter Gong on the circuit board according to the pre programmed program.

Advantages: various shapes of panel graphics can be produced on the board according to the program, and several boards can be overlapped and processed at the same time. The forming dimension accuracy of the Gong board is high, the interface of the Gong board is smooth, the stress is very small, and the cutting edge is free of burrs.
