PCB drilling is a key process in the entire printed circuit board production process.
Drilling takes up the longest production time, and its processing technology and manufacturing equipment level will directly affect the quality, performance and cost of the PCB (processing costs usually account for 30% to 40% of the PCB board manufacturing costs). PCB drilling mostly uses mechanical drilling and laser drilling methods. From the perspective of equipment cost and processing efficiency, more than 90% of the PCB drilling in the world currently uses CNC mechanical drilling, and laser drilling accounts for only about 10%. Therefore, CNC machine drilling is the mainstream of PCB precision drilling processing.

PCB CNC drilling machine is based on CNC technology. Through the coordinated movement of the three coordinates of X, Y, and Z, it controls the X and Y axes to move quickly and accurately to the drilling position, and the Z-axis actuator performs the drilling operation to achieve precision drilling processing. As the aperture of PCB becomes smaller and smaller and the number of holes increases, higher requirements are placed on the processing capacity of CNC drilling machine PCB micro-aperture.

The technical scope of PCB CNC drilling machines covers many fields: (1) mechanical manufacturing technology; (2) information processing and transmission technology; (3) automatic control technology; (4) servo drive technology; (5) sensor technology; (6) software technology, etc. Vigorously developing advanced manufacturing technology with CNC technology as the core has become an important way for countries around the world to accelerate economic development, improve comprehensive national strength and national status. With the rapid development of electronic communication products, the requirements for PCB manufacturing level are getting higher and higher. The number of layers of circuit boards is increasing, the line width is getting smaller, and the aperture is getting smaller and denser. The development of PCB technology has increased the demand for high-speed and high-precision CNC drilling machines. High-end CNC equipment has become the key to affecting the level of PCB manufacturing.

my country began to develop and produce PCB CNC drilling routing machines in the 1990s, along with the rapid development of my country's PCB manufacturing industry. Many companies, such as Shenzhen Zhijian Company, have developed and produced a batch of PCB CNC drilling machines with good performance and high precision. At the same time, the PCB high-speed CNC drilling machines in Taiwan, China, are also booming. They are in a dominant position in the mid-range equipment market and occupy half of the entire domestic drilling machine market. Low price and high cost performance have become the market winning magic weapon for domestic equipment manufacturers. Although domestic manufacturers have achieved great results in the mid- and low-end PCB CNC drilling machines and have made great progress in product functions and performance, there is still a gap between the micro-aperture processing capabilities that best reflect technical strength and the international advanced technology level, mainly reflected in processing accuracy and speed, degree of automation.
