The Rogers RO4003C PCB, a high-performance circuit board, has taken the electronics industry by storm with its exceptional electrical performance and remarkable manufacturability. This revolutionary PCB offers a cost-effective alternative to traditional microwave laminates without compromising on quality. With the Rogers RO4003C material at its core, this PCB delivers unparalleled performance, making it ideal for a wide range of applications. In this comprehensive productblog, we will delve deep into the features, benefits, construction details, statistics, and applications of the RO4003C PCB, highlighting its superiority in the market.

Introduction of RO4003C

The Rogers 4003C PCB is built using proprietary woven glass reinforced hydrocarbon/ceramic materials. It combines the electrical performance of PTFE (Polytetrafluoroethylene) with woven glass and the exceptional manufacturability of epoxy/glass. This breakthrough results in laminates that feature tight control of dielectric constant (Dk) and low loss.

What sets RO4003C laminates apart is their ability to achieve these impressive properties while utilizing the same processing method as standard epoxy/glass laminates, but at a fraction of the cost of conventional microwave laminates. Unlike PTFE-based microwave materials, no special through-hole treatments or handling procedures are required for the RO4003C PCB. It's important to note that RO4003C materials are non-brominated and not UL 94 V-0 rated.

One of the key advantages of RO4003C materials lies in their thermal coefficient of expansion (CTE), which offers several benefits to circuit designers. The expansion coefficient of RO4003C material closely aligns with that of copper, ensuring excellent dimensional stability. This stability is crucial for mixed dielectric multi-layer board constructions. Moreover, the low Z-axis CTE of RO4003C Substrate guarantees reliable plated through-hole quality, even in demanding thermal shock applications. With a glass transition temperature (Tg) exceeding 280°C (536°F), the expansion characteristics of Rogers RO4003C PCB materials remain stable throughout the entire range of circuit processing temperatures.
