TU-883 Very Low Loss and High Thermal Reliability PCB with ENIG and Pure Gold
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)
General Description
ThunderClad 2 (TU-883) is a very low loss printed circuit board material made from high-performance resin. This material is reinforced with standard woven E-glass and features a low dielectric constant and dissipation factor resin system, making it ideal for high-speed, low-loss, radio frequency, and wireless applications. TU-883 is compatible with lead-free processes and can also be used in FR-4 processes. The laminates offer excellent moisture resistance, improved Coefficient of Thermal Expansion (CTE), superior chemical resistance, thermal stability, and CAF resistance.
