高频混压板可以是FR4和高频板材的混合，或者不同DK的高频板材的混合，这种电路板具有耐高温性能和优异耐辐射性，这种结构的高频电路板能够满足局部高频信号传输的要求，领智电路是一家专业提供TU872 PCB打样，TU872 PCB加工，TU872 PCB批量制作等一站式印刷电路板的生产厂家。TU-872 LK is based on a high performance modified epoxy FR-4 resin. This material is reinforced with regular woven E-glass and designed with low dielectric constant and low dissipation factor for high speed low loss and high frequency multilayer circuit board application. TU-872 LK material is suitable for environmental protection lead free process and also compatible with FR-4 processes. TU-872 LK laminates also exhibit excellent CTE, superior chemical resistance, thermal stability, CAF resistance, and toughness enhanced by an allyl network forming compound.
