FR4, a fiberglass-reinforced epoxy laminate, boasts superior electrical insulation, high mechanical strength (bending resistance ≥340MPa), and thermal stability (-100°C to 130°C). Its CNC machinability enables precision-machined PCB substrates and insulating components via optimized tooling—tungsten carbide cutters at 100-200 m/min
Process Technology | Process Characteristics | FR4 Type | Applications |
---|---|---|---|
High-Temperature Lamination | High pressure (300-500 psi) at 170-190°C | All types | Multilayer PCB construction |
Precision Drilling | ±0.05mm accuracy with carbide bits | Standard, High Tg | Through-hole vias, component mounting |
Laser Micromachining | UV laser ablation (355nm), 20-100μm precision | All types | Microvias <0.15mm, HDI PCBs |
Photolithography | LDI/contact exposure, chemical etching | Copper-clad | Circuit pattern definition |
Surface Finishing | Electroless nickel immersion gold (ENIG) | All types | Solderable surfaces, contact pads |
CNC Routing | ±0.1mm dimensional accuracy | Standard, Lead-free | PCB outline cutting |
Solder Mask Application | UV-curable epoxy LPI coating | All types | Insulation, protection |
