F4BTMS255 PCB Double-Sided 60mil Thick with Immersion Gold
This double-sided PCB is engineered to meet the rigorous demands of high-reliability industries. It utilizes the advanced F4BTMS255 base material to deliver exceptional signal integrity, thermal stability, and mechanical durability. The board is compliant with IPC-Class-2 standards, undergoes 100% electrical testing prior to shipment, and is available for worldwide shipping.
Core Advantage: F4BTMS255 Aerospace-Grade Base Material
The F4BTMS255 is an upgraded flagship material, building on the F4BTM series with breakthroughs in formulation and manufacturing. It combines ultra-thin ultra-fine glass fiber cloth and uniformly distributed nano-ceramics with PTFE resin, minimizing glass fiber interference on electromagnetic waves while boosting key performance metrics. This makes it a direct replacement for premium foreign materials, ideal for aerospace and high-frequency applications.
