The IEC 60893-3 standard series provides detailed specifications for industrial rigid laminated sheets used in electrical applications. These sheets are primarily composed of thermosetting resins and are reinforced with various materials such as cellulose paper, glass cloth, and polyester cloth. The standard is divided into several parts, each focusing on different resin types and their respective requirements. Read More

MIL‑I‑24768 stands as the backbone for military thermoset laminates used in applications requiring rigorous insulation, durability, and reliability. This specification ensures that every laminate—whether for electronic circuit boards or for high-temperature structural components—meets both stringent performance and safety standards. By dictating criteria for material composition, precise dimensions, electrical and mechanical performance, and environmental endurance, MIL‑I‑24768 helps streamline quality and interoperability throughout military and aerospace supply chains.
