PCB drilling template manufacturing: PCB wire cutting with large wire tracks
In an era of rapid iteration of electronic devices, the manufacturing accuracy of printed circuit boards (PCBs), as the "nerve center" of electronic products, is related to the performance of the entire device. As a key component to guide drilling accuracy, the processing quality of PCB drilling templates is of paramount importance. How to achieve high-precision and high-efficiency PCB drilling template manufacturing? Large-scale linear track wire cutting equipment is becoming a core weapon for printed circuit board manufacturers to break through bottlenecks.
Take a printed circuit board manufacturing company as an example. In the production process of PCB drilling templates, large-scale linear track wire cutting equipment plays an irreplaceable role. PCB drilling templates need to process hundreds of tiny and precisely arranged holes on high-precision metal plates. The dimensional accuracy and position accuracy of these holes directly affect the accuracy of the subsequent drilling process of the PCB . Once the template hole deviation exceeds 0.02mm, it may cause the PCB drilling to be misaligned, causing serious problems such as short circuits and failure to install components normally, thereby greatly increasing the defective rate of products.
Large-scale linear rail wire cutting equipment, with its unique advantages, perfectly meets the manufacturing needs of PCB drilling templates. Zhikai CNC's large-scale linear rail wire cutting equipment adopts a high-rigidity linear rail transmission system, combined with a high-precision servo motor and CNC system, which can achieve a positioning accuracy and repeatability of ≤ ±0.00 3 mm, ensuring that each hole on the template is accurate. During the cutting process, the equipment can control the movement trajectory of the electrode wire through programming, and efficiently process various complex hole shapes such as round, square, and special-shaped holes to meet the production requirements of PCB drilling templates of different specifications. At the same time, the equipment is equipped with an intelligent pulse power supply system that can automatically adjust the discharge parameters according to the thickness and material of the plate, while ensuring the cutting efficiency, so that the surface roughness of the template reaches Ra ≤0.7-1.4 μm or less, reducing subsequent grinding processes.
However, the manufacturing of PCB drilling templates faces many challenges. On the one hand, the templates are mostly made of alloy materials with high hardness and strong wear resistance. During the cutting process, the electrode wire is lost quickly and it is easy to generate heat, causing material deformation. On the other hand, with the continuous improvement of PCB circuit integration, the hole density and precision requirements of the drilling template continue to rise. Traditional processing methods are inefficient and have low yield rates when processing high-density and small apertures. In addition, complex hole layouts also place higher demands on programming accuracy and equipment computing power.
Zhikai CNC has been deeply engaged in the pain points of the industry and has continued to increase its R&D investment. In response to the problem of electrode wire loss, it has developed intelligent electrode wire automatic compensation technology, which monitors the loss in real time and dynamically corrects the cutting path, reducing electrode wire loss by 40%; in order to deal with the problem of material deformation, it has innovatively designed an intelligent temperature control system to ensure processing stability through precise temperature control. At the same time, the AI programming system developed by Zhikai CNC supports direct import of Gerber files, automatically identifies hole position information and generates the optimal cutting program, greatly improving programming efficiency and accuracy.
