PCB materials types included HB sheet and V0 sheet
HB sheet has low flame retardancy and is mostly used for single-layer PCB. VO sheet has high flame retardancy. It is mostly used in double-sides and multi-layer boards. This type of PCB sheet meets V-1 fire rating requirements and becomes FR-4 sheet.
When designing a PCB to factory fabrication, how to choose PCB material?
PCB material classification:
1. According to different materials (the most commonly used classification method)
Paper substrate (FR-1, FR-2, FR-3)
Epoxy glass cloth substrate (FR-4, FR-5)
Composite Substrates (CEM-1, CEM-3)
HDI sheet (RCC)
Special substrates (metal substrates, ceramic substrates, thermoplastic substrates, etc.)
2. Divided by resin
Phenolphthalein resin
