A Study on Conductive Polymer in PCB Manufacturing

Abstract Making Hole Conductive is one of the key technologies in Printed Circuit Board manufacture. For a long time, electroless copper was the unique technology of hole metallization process. However, it’s long process, high water consumption and the resulting huge amount of waste water. A large number of toxic and harmful chemicals are also discharged into the environment, causing great harm to the health of workers and the environment. In this paper, the environmentally materialization technology-selective organic conductive coating (SOC) technology was studied. The resource consumption, product quality, and environmental and economic benefits of the traditional PTH and new SOC technology applied in the making hole conductive were compared and analyzed in detail through the investigation of long-term operation examples. The necessity, advantages and practicality of SOC technology were revealed.
