Human development is always closely related to the environment. In the electronics industry, halogen-free laminates and lead-free processes are the two core concerns. The development of halogen-free laminates was in the mid-1980s, and the real industrialization was around 1997. The [...]

Human development is always closely related with the environment. In the electronics industry, the substrate of halogen-free and process lead-free is the the two core focus. Halogen-free substrate development work is in the mid-80s of 20th century, the real industrialization [...]
