1. Introduction of 2-Layer Rogers TMM4 PCB
Rogers TMM4 2-Layer High Frequency PCB is a high-performance rigid circuit board specifically engineered for RF, microwave, and high-frequency applications, leveraging the advanced properties of Rogers TMM4 thermoset microwave material. As a ceramic-hydrocarbon thermoset polymer composite, 2-layer TMM4 PCB combines the mechanical robustness of ceramic laminates with the processability of traditional materials, eliminating the need for specialized production techniques often required for PTFE-based boards. Measuring 102mm x 85mm (±0.15mm) with a finished thickness of 0.5mm, this PCB is designed to deliver consistent electrical performance and reliable functionality, making it an ideal choice for demanding high-frequency projects. Each unit undergoes 100% electrical testing prior to shipment, ensuring compliance with IPC-Class-2 standards and meeting the rigorous requirements of global markets. The board features 1oz outer copper weight (35μm), 20μm via plating thickness, and an Immersion Gold surface finish, paired with no silkscreen or solder mask on either side, optimizing it for high-frequency signal integrity. With a minimum trace/space of 5/7 mils and a minimum hole size of 0.4mm, Rogers TMM4 high-frequency material balances precision with manufacturability, suitable for a wide range of high-frequency electronic assemblies available worldwide.
