What can we do in SMT environmental development?

What can we do in SMT environmental development? the PCB circuit board !- It is natural for PCB circuit boards to develop towards environmental protection. We all know that the development trend of modern electronic equipment is turning to miniaturization, light weight and multi-function, and corresponding to the global environmental protection promotion, environmental protection is the follow-up direction of development. As a basis, printed circuit boards should naturally move closer to these directions, and the materials used in printed circuit boards should of course meet the needs of these aspects.So, author from qihe smt pick and place machine tell you about it today .
