Most commonly woven E-glass fiber, though specialty fibers exist for aerospace or high-frequency applications.

The temperature at which the chemical bonds of the resin break down, causing weight loss. High Td is crucial for lead-free soldering operations.

Adhering to IPC-4101 ensures consistency across global manufacturing by providing standardized test methods (via ) to verify material performance. This minimizes risks like delamination , warping, or signal integrity loss, particularly in high-frequency applications like 5G or automotive systems.

The standard defines and sets compliance thresholds across three foundational pillars:

: Over 60 slash sheets cover various resin systems (epoxy, polyimide, cyanate ester) and reinforcement materials (woven E-glass, cellulose paper, aramid fiber). Most commonly woven E-glass fiber, though specialty fibers

IPC-4101 defines the rigorous requirements for (rigid cores) and prepregs (the bonding layers used in multilayer boards). Originally released in 1997 to replace the military standard MIL-S-13949, it has evolved through multiple revisions (A through E) to keep pace with lead-free soldering and high-frequency 5G requirements.

Added new specification sheets specifically targeting halogen-free materials and high-speed, low-loss digital applications. IPC-4101 defines the rigorous requirements for (rigid cores)
