aterials have different performance impact, especially in light of decline is particularly prominent. This was mainly due to the thermal conductivity of copper a lot better than iron, copper, thermal conductivity of 398W (mk), while the thermal conductivity of iron is only 50W (mk) about the former is only 1 / 8, as well as support the plating thickness also closely related. In the selection of scaffolds, but also pay attention to whether the support of the bowl cup size particles with light-emi
