Why is there such a big price difference between imported PCB laser cutting machines and domestic PCBs?

Compared with European and American countries, China's scientific and technological level has always been relatively backward. In the field of PCB laser cutting, domestic science and technology laser technology started late, and core equipment relied on imports. The laser components of PCB laser cutting machines, especially high-power ultraviolet lasers from developed countries such as the United States, have long relied on imports. The quality of imported equipment is often twice that of domestic equipment, and high equipment maintenance fees will also be charged. So, what is the main difference for this reason?

PCB laser cutting machine is mainly divided into four modules: optical system, mechanical system, software control system, and auxiliary system.

Optical system

The optical system includes laser, galvanometer, field mirror, radiation mirror, adjustment frame, laser mirror, etc.

The domestic optical system lags behind the important level of PCB laser cutting machine and imported PCB laser cutting machine. Due to the shortage of technology and the expensive imported equipment, it is difficult for domestic equipment to break through the technical barriers, especially in the early days of foreign blockade, it is difficult to buy high-power UV lasers. Until now, the domestic market cannot buy UV lasers above 60W. Although domestic high-power UV lasers have been localized, their core equipment currently uses imported modules. It is worth mentioning that the crystal manufacturing technology in the laser components in the United States has always been lacking in technology. Crystal manufacturing technology did not start until the past two years, and domestic crystals have always been in the leading position in this regard.

The technical shortage of the optical system mainly comes from the laser core module technology. The accuracy, speed and control system technology of the high-speed vibration mirror have not yet reached foreign standards. The field mirror, especially the telecentric mirror, cannot be positioned, which is mainly reflected in the shortage of coating technology and basic lens manufacturing technology.

Mechanical system

Mainly used for linear motors and Z-axis motors. In contrast, we are familiar with this field. Overall, the accuracy of PCB laser cutting machines is caused by many factors, and the accuracy of motors is particularly important. Although domestic motors are more common, the equipment for domestic motors is imported by ourselves.

Software control system

Compared with the disadvantages in the software field, the localization process of software control technology is faster. The disadvantage of domestically produced PCB laser cutting machine software is the shortage of control system talents. The advantage of imported PCB laser cutting machine software control is the physical design, which is more in line with humanized requirements, with fewer software bugs and strong software versatility. Usually, some application software control ports of imported equipment will not be open to customers. If they need to be opened, additional charges are required. The advantage of domestically produced PCB laser cutting machines is that the site can be changed at any time according to customer needs, and the port can be opened, which also leads to insufficient program stability and no stability and macro control capabilities.

Auxiliary system

The accuracy of the auxiliary system is also very important. For example, the marble platform, rack, overall flatness, and levelness all affect the accuracy, often affecting the accuracy, often affecting the accuracy. PCB laser cutting machine manufacturers need to spend a lot of time adjusting the equipment level through tools at the manufacturer or even the equipment site. In this regard, local products lack the spirit of craftsmanship, the price is right, and they are not returned to customers according to their own standards.

Summary: The essential difference between domestic PCB laser cutting machines and imported equipment lies in the quality control capability, and imported equipment is also integrated assembly. Why do other equipment have high assembly precision and high stability? On the one hand, it is the tools and instruments of domestic equipment, and on the other hand, it lacks craftsmanship and factory quality control and management. Similarly, due to price wars, some manufacturers have more disadvantages, which is also a market strategy, and there is also such a successful case. The fact is that compared with the competitiveness and core technology of imported equipment, there has never been a breakthrough, which is worth reflecting on.
