How are PCB PCB substrates classified?
Substrate, as the name implies, is basic, is the basic material of manufacturing ກະດານວົງຈອນພິມ, the general PCB substrate is composed of resin, reinforcement materials, conductive materials, there are many kinds. Resin is more common epoxy resin, phenolic resin, reinforcement materials including paper, glass cloth, etc., the most commonly used conductive material is copper foil, copper foil is divided into electrolytic copper foil and calendered copper foil.
PCB substrate material classification:
One, according to the reinforcement materials:
1. Paper substrate (FR-1, FR-2, FR-3);
2. Epoxy glass fiber cloth substrate (FR-4, FR-5);
3. Cm-1, CM-3 (Composite Epoxy Material Grade-3);
4.HDI (High Density Interconnet) sheet (RCC);
Special substrate (metal substrate, ceramic substrate, thermoplastic substrate, etc.).
