The Best Rogers PCB Manufacturer in China
Rogers PCB is a type of high-frequency board that raw material is produced by Rogers company. It is different from the conventional PCB board—epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as the high-frequency material. Rogers has superior dielectric constant and temperature stability. Its dielectric constant thermal expansion coefficient is very consistent with copper foil, which can be used to improve the deficiencies of PTFE substrates. It is very suitable for high-speed electronic design, commercial microwave, and radio frequency applications. Its low water absorption is ideal for high-humidity applications, providing customers in the high-frequency board industry with the highest quality materials and related resources, which fundamentally enhance product quality.
ROGERS 4003C and ROGERS 4350B have excellent low dielectric loss characteristics. As a result, they provide a more cost-effective and processable high-frequency material selection than PTFE. They are widely used in antennas of the cellular base station and power amplifiers, microwave point-to-point connection (P2P), automotive radars and sensors, radio frequency identification (RFID), direct broadcast satellite high-frequency head (LNB), and other fields. In addition, the thermal expansion coefficient of the X and Y-axis is similar to that of copper. The expansion coefficient of the Z-axis is much lower than FR4 (46ppm/ oC) and has a higher Tg value (>280oC), thus ensuring good thermal stability. The dimensional stability and high reliability of the entire product in PCB processing and assembly will bring more benefits to the design of multilayer circuits.
When the circuit’s operating frequency is above 500MHz, the range of materials that design engineers can choose is significantly reduced. Rogers RO4350B material allows RF engineers to conveniently design circuits, such as network matching and impedance control of transmission lines. Due to its low dielectric loss characteristics, in high-frequency applications, RO4350B material has more advantages than ordinary circuit raw materials. Its dielectric constant with temperature fluctuation is almost the lowest among similar materials. In a wide frequency range, its dielectric constant is also relatively stable at 3.48; the recommended design value is 3.66. LoPra copper foil can reduce insertion loss, which makes the material suitable for broadband applications.
