Since 2011, YUESHAN has helped PCB manufacturers worldwide cut exit burrs, extend drill life and simplify their consumable supply chain.
Since 2011, YUESHAN has helped PCB manufacturers worldwide cut exit burrs, extend drill life and simplify their consumable supply chain. We focus on one thing: the materials under and above your drilling stack, backup boards, aluminum entry boards, coated lubricant aluminum and back-drill sheets, engineered, toleranced and delivered consistently.

We focus on one thing: the materials under and above your drilling stack. Backup boards, aluminum entry boards, coated lubricant aluminum and back-drill sheets — engineered, toleranced and delivered consistently, order after order.
Hardness, density (±30 kg/m³) and flatness (≤0.10 mm) are stated and toleranced — not vague.
Customers across Europe have re-ordered continuously for 15 years. Consistency is the product.
Send us your stack, hole size and target — we recommend the right grade, free.
Shipping to India, Japan, Korea, Europe, Middle East & Russia with formula-based pricing.
PCB manufacturers in 30+ countries run YUESHAN materials in daily production — from HDI and multilayer lines in India and Southeast Asia to specialty backup-board applications in Europe, the Middle East, and beyond. Customers stay with us for the consistency: some have re-ordered continuously for 8–15 years across multiple product grades.




Our quality system and material compliance are verified by independent bodies. Verification documents are available on request.
