FR4 printed circuit board (PCB)
Classic composite PCB of glassfiber and expoxy resin, available in various compounds, versions (single-/multilayer) and thickness (0.3-3.5mm)
Designation | Material | Note |
FR4 Standard | Epoxy + glass fabrics | Tg=130-140C, RoHS/WEEE compliant |
FR4 non-halogen | Epoxy + glass fabrics | Tg>150, CAF-resistant |
FR4 mid Tg | Epoxy + glass fabrics | Tg: 140-160C, increased thermal stability, low elongation in z-axis, high steadiness at lead-free soldering, often CAF-resistant. |
FR4 high Tg | Epoxy + glass fabrics | Tg: 160-190C, increased thermal stability, low elongation in z-axis, high steadiness at lead-free soldering, often CAF-resistant. |
