Finished PCB copper has 1oz and 2oz. Our maximum PCB size on high frequency material is 400mm by 500mm, it can be a single board in the sheet and also can be different designs in this panel. Solder mask of green, black, blue and yellow etc is available in house. There’s immersion gold, HASL, immersion silver, immersion tin, bare copper etc. for pads plating. RT/duroid 6002 PCB has tight thickness control with low out-gassing. It is very suited to the equipment of flat and non-planar structures, such as antennas, complex multi-layer PCBs with inner-layer connections, and microwave PCBs for aerospace designs in hostile environments.

Rogers RT/duroid 5880LZ laminates are filled PTFE composites designed for exacting strip-line and micro-strip circuit applications. They contain a unique filler that results in a low density, lightweight material for high performance and weight sensitive applications. RT/duroid 5880LZ has Z-axis coefficient of thermal expansion (CTE) at 40 ppm/°C. This is a low value that ensure its reliable plated through holes. When ordering RT/duroid 5880LZ PCB, it is important to specify the dielectric thickness, weight of copper foil required and surface finish.

There is an episode abouthigh frequency PCB built on RO3006 material. Rogers RO3006 printed circuit boards are ceramic-filled PTFE composites designed to offer exceptional electrical and mechanical stability at competitive price, intended for use in commercial microwave and RF applications Firstly, RO3006 has a dielectric constant of 6.15 +/-.15. The high dielectric constant enable designers to design the circuit board smaller. So we can miniaturize our circuit size using RO3006. The DK is stable over a wide range of temperatures, so this eliminates the step change in Dk that occurs for PTFE glass materials near room temperature. The next issue would be the dissipation factor. It’s a very low loss, 0.002 dissipation factor when it’s tested in 10 GHz. And that’s very low loss which helps power amplifier for high gain. The third one we need to mention is the thermal conductivity. RO3006 material is very good for thermal conductivity. It’s got a number of 0.79 W/m-K, that’s considered very high for thermal conductivity and that does really help thermal management issue for power amplifiers. Lastly, the coefficient of thermal expansion (CTE). Ideally that should be at 17 ppm/℃because that’s the value of CTE of copper. As you can see the coefficient of thermal expansion of RO3006 on X and Y axis is 17 ppm/℃which is matched to copper and Z-axis is as low as 24 ppm/℃. This allows for more reliable surface mounted assemblies, it’s ideal for applications sensitive to temperature change. That’s considered pretty good for the plated through holes reliability and excellent dimensional stability. RO3006 PCB also has very low water absorption at 0.02%. The manufacturing process is similar to standard PTFE PCB, so we can get volume manufacturing process and economical pricing to win the market.

As we know, Rogers starts from its RO3000 series, RO4000 series, RT/duroid 5000 series and RT/duroid 6000 series. Subsequently, AD series, DiClad, CuClad and TMM series come into the line card. Taconic, There’s TLX series, RF series and TLY series, such as base station antenna (TLX-8, RF-30), satellite communication terminal antenna (RF-10), high power and miniaturized amplifier (RF-35, RF-60), millimeter wave RF backplane (TLY-5Z), etc. Wangling, a 38-year-brand factory, alternative and competitive RF material manufacturer in many areas of aerospace and aviation, satellite communication, navigation and radar, electronic countermeasure, 4G and 5G communication etc. F4B (PTFE) and composite dielectric substrates are the main product lines. RO3000 Series laminates are ceramic-filled PTFE composites with consistent mechanical properties and electrical stability, regardless of what DK value selected. This allows the designer to develop multi-layer board designs that use different dielectric constant materials for individual layers, without encountering war-page or reliability problems. Additionally, the RO3000 series’ dielectric constant is stable over a wide temperature range. They are intended for use in commercial microwave and RF applications. Rogers RO4000 Series materials are woven glass reinforced hydrocarbon ceramic laminates. They are well controlled dielectric constants and wide range available (2.55-6.15). Above-average thermal conductivity (0.6-0.8W/mK), low Z-axis CTE for reliable plated through-hole and optimized cost and RF/ microwave performance are the robust attractiveness to the market. Rogers RT/duroid high frequency circuit materials have 5000 series and 6000 series. These are random glass or ceramic filled PTFE composite laminates for use in high reliability, aerospace and defense applications with long industry presence of providing high reliability and superior performance. They feature low electrical loss, low moisture absorption, low outgassing for space applications and stable Dk over wide frequency range. OK, Rogers’ AD series and CLTE series, the dielectric constant presents a low value, ranging 2.5 to 3, except 10.2 of AD1000. The series of CuClad, DiClad and IsoClad laminates feature much lower dielectric constants (Dk) ranging from 2.17 to 2.40, lower electrical loss of tan δ from 0.0009 to 0.0018 at X-band and lower moisture absorption. TC series are woven glass reinforced PTFE ceramic composites with higher thermal conductivity, which provides higher power handling, reduces hot-spots and improves device reliability and reduced operating temperatures in high power applications. We benefit from their stable Dk across wide temperature range, low loss tangent of .002 at 10 GHz and low coefficient of thermal expansion on X,Y and Z axis. Rogers TMM series are hydrocarbon ceramic, thermoset microwave laminates combining exceptionally low thermal coefficient of dielectric constant (TCDk), wide range of Dk, copper matched CTE...
