Environmental guidelines
Green PCB Production Process—Environmental Standards and Commitment to Sustainable Development
Core Environmental Standards
✔ RoHS 2.0 compliant: Strict limits on 6 categories of hazardous substances such as lead, cadmium, and mercury
✔ REACH SVHC control: Comprehensive screening of 218 substances of very high concern
✔ Halogen-free substrate: Bromine/chlorine content <900ppm (meets IPC-4101B standard)
✔ Wastewater treatment: Heavy metal ion concentration below 0.5mg/L (stricter than national standard GB8978)
Highlights of environmentally friendly production processes
1. Material Selection
• Prioritize the use of halogen-free copper-clad laminates from brands such as Shengyi and Taiguang
• Biodegradable packaging materials (PE-free) and environmentally friendly inks
2. Clean Production
• Etching solution recycling system: Copper recovery rate ≥95%
• Micro-etching waste liquid treatment: Neutralization precipitation + membrane filtration technology
• Laser drilling dust removal: Equipped with HEPA high-efficiency filtration device
3. Energy Saving and Consumption Reduction
• Electroplating line intelligent rectifier saves 30% energy
• Waste heat recovery system used in lamination process
4. Waste Management
• 100% classified recycling of waste copper foil/scraps
• Hazardous waste is handed over to qualified handlers (with SGS compliance report)
