Packaging Solutions Exceeding US Military Standards
In the US high-end electronics manufacturing industry, ESD packaging technical specifications have evolved from qualitative requirements to precisely quantified engineering parameters. When a packaging bag’s inner surface resistivity is precisely controlled at 10^5-10^10Ω/sq, outer layer <10^8Ω/sq, and electrostatic decay time breaks the 0.05-second threshold, this not only signifies exceptional product performance but represents systematic breakthroughs in materials science and manufacturing processes.
