TU-872 LK and TU-87P LK PCB Materials

Overview

TU-872 LK and TU-87P LK are PCB materials with low Dk/Df and high thermal reliability. TU-872 LK is formulated using high-performance modified epoxy resin FR-4.

Material Composition and Properties

This PCB material is reinforced with ordinary woven E glass and designed to have a low dielectric constant and low loss factor, making it ideal for high-speed low-loss multilayer PCB and high-frequency multilayer PCB board applications. TU-872 LK PCB material is compatible with environmentally friendly lead-free processes and also with FR-4 processes. Inoltre, TU-872 LK multilayer PCB material demonstrates excellent CTE, superior chemical resistance, thermal stability, CAF resistance, and enhanced toughness due to compounds forming an allyl network.

Industry Approvals

TU-872 LK and TU-87P LK have received IPC-4101E Type Designations: /29, /99, /101, /126. They are IPC-4101E/126 Validation Services QPL Certified and have a UL designation of ANSI Grade: FR-4.0. The UL file number is E189572, with a Flammability rating of 94V-0 and a Maximum Operating Temperature of 130°C.
