Yes, it is a double-sided adhesiveless copper-clad laminate. It is a composite material made by laminating a layer of copper foil onto a substrate, which in the case of SF202, is made of polyimide or polyester.
The absence of an adhesive layer between the copper and substrate allows for a thinner and more uniform copper layer, which can result in improved electrical performance. Being adhesiveless can also simplify the production process and reduce the potential for delamination during use.
Yes, this material is halogen-free. It uses a resin system containing no halogenated compounds known to release toxic fumes when burned.
This material is ideal for applications where safety and environmental concerns are prioritized. In addition to being halogen-free, this complies with other environmental standards, including the European Union’s Restriction of Hazardous Substances (RoHS).
