Analysis of the development trend of PCBA sub-board machine in electronic manufacturing factory

PCB (PrintedCircuitBoard), Chinese name for printed circuit board, also known as printed circuit board, printed circuit board, circuit board, PCB circuit board, etc. are important electronic components, is the support of electronic components, is the electrical connection of electronic components Provider. Because it is made by electronic printing, it is called a "printing" circuit board. 4-LAYER RIGID-FLEXIBLE BOARD.

PCB panels are mainly used to make full use of the sheet to improve SMT production efficiency. Usually, after the PCB is soldered, each independent function PCB board should be cut. With the miniaturization of components, the printed circuit board (PCB) assembly process brings great challenges. Advanced level surface assembly technology (SMT) equipment has become an urgent need for the development of domestic precision manufacturing equipment and modern control technology.

PCBA splitter is generally divided into v-cut splitter and stamp hole milling cutter type splitter, no V-slot splitter (punch splitter), v-cut splitter is common Board machine, the characteristics are as follows:
1. The PCB does not move during the cutting process, and the round knife slips to ensure that the electronic components of the substrate are not damaged by the movement.
2, round knife slip speed can be adjusted
3. In view of the shallow depth of the V-groove and the loss of the tool, the distance between the upper and lower straight knives can be accurately adjusted.
4, can solve the parts across the V-slot to achieve the board
5. Minimize the internal stress generated when cutting the board to avoid tin cracking
6, the cutting speed is controlled by the knob, the board stroke can be freely set and has LCD display
7, can be added conveyor belts according to requirements, improve performance
8, three sets of electric eye protection to ensure safe production .  Multiple Flex-Rigid Board factory.

The stamp hole milling cutter type PCB splitting machine is also called the stamp hole PCBA substrate cutting machine, which uses a high-speed rotating spindle (Spindle) to drive the milling cutter to carry out the substrate cutting automation equipment according to the design route.

Compared with traditional handcuffs, stamping, etc., it has the following characteristics:
1. The cutting stress is smaller, about 1/10 of the stamping type and 1/100 of the handcuff, thereby preventing the chip such as ceramic capacitor from being damaged during the cutting process;
2, can be cut on the PCBA substrate in a variety of shapes such as straight lines, arcs, etc., so the constraints on the substrate design are greatly reduced;
3, high cutting precision, smooth cutting surface without burrs, to meet customer demand for high-quality production processes.
4. Compared with the stamping type, the running cost is greatly reduced. Screen Printing Bending Ink wholesales.

The stamp holes of the artificial hand-folded pcb board are not well-formed, and the stamp hole of the cutting is smooth. The high-speed spindle motor is used to cut the PCB, which effectively reduces the cutting pressure. At the same time, the high-precision servo motor is used to make the cutting precision more suitable. .

With the miniaturization of components, the printing circuit board (PCB) assembly process has brought enormous challenges. The development of internationally advanced surface assembly technology (SMT) equipment has become the development of domestic precision manufacturing equipment and modern control technology. urgent need. At present, more SMT electronics factories are willing to use pneumatic boring type PCBA board machine.

At the same time, with the increasing precision of SMT electronic technology, the traditional sub-board method has been difficult to meet the production requirements, and the cost of labor is getting higher and higher, so this level of SMT business will be forced to introduce fully automatic Stamp hole milling cutter PCB splitter to replace it.
