Four-Layer Circuit Board (4-Layer)1. Layer StructureTypical stack-up:Layer → Prepreg → GND Layer → Core → PWR Layer → Prepreg → Bottom Layer(Top signal, ground, power, bottom signal). Core AdvantagesCost-effective: Compared to a double-sided board, adding a power/ground layer, the cost is only 50%~6

FR-4 (Glass fiber epoxy resin)Features:FR-4 is a glass fiber fabric reinforced epoxy resin with a medium dielectric constant (Dk 4.5-5.5), low dielectric loss (Df 0.02-0.03), high mechanical strength (bending strength ≥400 MPa), and UL94 V-0 flame retardancy.Advantages:Low cost: Material cost is 50%
