PCB News - The PCB industry needs to pay attention to environmental governance

The PCB industry needs to pay attention to environmental governance. New technologies are constantly being implemented.

The increasingly severe environmental problems have caused the environmental and resource issues and sustainable development issues of the PCB copy board industry to be placed at an unprecedented strategic height. The development of China's PCB industry must strengthen environmental governance and enable it to embark on a circular economy track of cleaner production so that the PCB industry can become a resource-saving and environment-friendly industry. Therefore, PCB companies must actively face this situation, accelerate technological innovation and industrial revolution in traditional PCB production.

Truly realize energy saving and emission reduction, and even pollution-free production. the China Printed Circuit Industry Association (CPCA), said that printed electronics (digital inkjet printing) technology will lead the PCB industry on the road to "green production". At present, some developed countries in the world have invested heavily in the research and development of this technology.

The conventional manufacturing process of printed circuit boards is the copper foil etching method, also known as the subtractive method. It uses a copper-clad laminate as the substrate, which is screen-printed or photo imaged to form a corrosion-resistant circuit pattern, and the circuit is obtained by chemical etching; if it is double-sided or multilayer PCB, hole metalization and electroplating are required to achieve interlayer Circuit interconnection. Therefore, the PCB manufacturing process is complicated and processes are many, which will inevitably consume a lot of water and electricity, and also consume a lot of copper and chemical materials, and generate a lot of wastewater and pollutants. The development trend of electronic equipment is multi-function, miniaturization, environmental protection, and low cost, which correspondingly requires high density, light and thin, environmental protection, and low cost for its supporting PCB. The traditional PCB copy board technology and products are obviously difficult to achieve New generation requirements. At present, a PCB technology revolution is emerging in Europe, America, Japan, South Korea, and Taiwan my country-Printed Electronic (Printed Electronic) or Printed Electronic Circuit (PECPrinted Electronic Circuit), also known as the additive method.

This revolutionary new technology is to use functional inks to directly print electronic circuits on insulating substrates, such as printing conductive inks on flexible organic films to obtain conductive circuits, and printing semiconductor inks to obtain transistors or memory elements. This new generation of printed electronic circuits is a component that contains electronic connection circuits and components, which will replace the traditional printed circuit board to install components. This technology can greatly reduce the discharge of wastewater and pollutants, and it is also an effective measure technology for environmental protection.
