Electroless copper plating process "OPC SUBLET process" that achieves high connection reliability.
In recent years, the application environment for printed circuit boards has expanded, particularly in fields related to electric vehicles and autonomous driving, where there is a strong demand for improved reliability of interlayer connections, heat resistance, and durability. Additionally, in response to environmental regulations such as the RoHS directive, there is a consideration to switch the solder used in assembly from low-melting-point Sn-Pb solder (melting point 183°C) to high-melting-point solders such as Sn-Ag (melting point approximately 220°C). Therefore, our company has newly developed an electroless copper plating process that can maintain connection reliability even under severe conditions such as high temperature and high pressure.
