PCB manufacturers in the production process of grinding board, etching, electroplating, Hole metallization, development, striping and other processes will produce waste water.
Whatever the internal quality is, the surface is almost the same. The internal differences is very important in the life of the PCB in the durability and function
In order to adapt to the development of electronic products, PCB circuit boards from simple single-sided PCB transit to double-sided/multilayer PCB/blind buried circuit board/multilayer impedance board, until todays high-density HDI circuit board
the development of the PCB industry in Korea has three characteristics, the rapid development of scale, vertical integration of industry, and gradually turn to high value-added PCB products
