PCB Grades and Specifications:
- 94HB: Basic cardboard material, not fireproof, suitable for die punching but not recommended for power supply boards.
- 94V0: Flame-retardant cardboard, die-punched for improved safety.
- 22F: Single-sided half glass fiber board, die-punched for specific applications.
- CEM-1: Single-sided fiberglass board requiring computer drilling.
- CEM-3: Double-sided semi-glass fiber board, cost-effective for simple double-sided boards.
- FR-4: High-quality double-sided fiberglass board.
Additional Insights:
- Flame Retardant Grades: Different grades like 94V-0, V-1, V-2, 94-HB offer varying flame retardant properties.
- Semi-Cured Film Thickness: Specifications like 1080, 2116, 7628 indicate different film thicknesses.
- Material Clarification: FR4 CEM-3 signifies a glass fiber board with CEM-3 as a composite substrate.
- Halogen-Free Consideration: Use materials free of halogen elements for environmental protection during burning.
- Tg (Glass Transition Temperature): Crucial for flame resistance, Tg indicates the point where the PCB softens without burning, ensuring stability.
