And advanced resin matrix composites incorporating aluminum for lubrication in drilling, characterized in that it is possible to increase production efficiency in order to simplify the production process and to achieve mass production purposes, and thus suitable for application to equipment for drilling electric boards. .

In recent years, as electronic technology continues to improve and many high-tech electronic industries continue to emerge, more and more humanized and better functioning electronics suggest new ideas based on old ones, and these electronics are thin and It continues to evolve in the pursuit of shorter, smaller, and lower weight designs. In all types of electronics, there are many electronic devices and main boards that make up the circuit board. The function of the circuit board includes supporting and connecting the individual electronic devices so that the electronic devices can be electrically connected to each other. The most common circuit board at present is a printed circuit board (PCB).

Printed circuit boards cannot connect electronic components with each other to achieve their integration functions and thus become independent basic components in all electronic information products. Because the quality of printed circuit board design not only affects the reliability of electronics but also plays an important role in the competitiveness of the system, PCBs are called "the mother of electronic system products" or "the foundation of the 3C industry." Printed circuit boards made of non-conductive materials are flat plates. This plate is usually designed to have pre-drilled holes for installing chips and other electronics. Holes in the elements facilitate electronic connection of pre-defined printed metal circuits to the surface of the board. When the device's connecting legs pass through the PCB, the circuit is formed by attaching the device onto the PCB with a conductive metal welder.

However, breakage of the drilling needle often occurs while drilling the electrical board. Modern technology has shown that when placed on drilled electrical boards, the reduction in needle failure rate can be achieved by wetting and buffering from water-soluble resin and heat-dissipating from aluminum foil. It has the advantage of applying a water soluble resin on the aluminum foil to form the material. Nevertheless, the complexity of the formulations constituting conventional buffering materials not only results in complex manufacturing processes and low production rates, but also results in insufficient drilling stability using these buffering materials.
