If you're a European PCB manufacturer or a supplier to European markets, environmental compliance isn't optional — it's a regulatory gate. And when it comes to drilling materials, the compliance risks are often hidden.
Three Regulations That Matter
1. VOC (Volatile Organic Compounds)
What it regulates: Emissions of volatile chemicals during manufacturing.
The risk with backup boards: Some low-cost UV-coated backup boards use reclaimed UV coating mixed with calcium carbonate filler. This reclaimed material may contain residual solvents that exceed European VOC limits.
How to verify:
- Request a VOC test report from the supplier
- Confirm the UV coating uses new material, not reclaimed
- Check for calcium carbonate filler content (high filler = likely reclaimed coating)
YUESHAN policy: All UV-coated products use new UV materials. VOC test reports available on request.
2. REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals)
What it regulates: Chemical substances used in products sold in the EU.
The risk: Backup boards and entry sheets contain resins, coatings and adhesives that may include SVHCs (Substances of Very High Concern). If a product contains >0.1% of an SVHC, it must be disclosed.
How to verify:
- Request a REACH compliance declaration
- Ask for the full substance list (not just "compliant" — get specifics)
- Verify the declaration covers all SVHCs on the current candidate list (updated regularly)
3. RoHS (Restriction of Hazardous Substances)
What it regulates: Ten restricted substances in electronic equipment — lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, and four phthalates.
The risk: While backup boards and entry sheets are "consumables" rather than "electronic equipment," many PCB manufacturers require RoHS compliance from all materials that contact their products — to prevent contamination.
How to verify:
- Request RoHS test report (not just a declaration)
- Confirm the test covers all 10 restricted substances
- Check the test date — the RoHS substance list has expanded over time
The Hidden Cost of Non-Compliance
A backup board that saves $1/panel but carries VOC non-compliance risk can cost far more:
- Production shutdown if discovered during inspection
- Fines under European regulations
- Product recall if boards were used in shipped PCBs
- Reputational damage with end customers
Experienced European PCB buyers know this well. When a lower-cost alternative appears, the $1/panel saving rarely justifies the regulatory risk. Compliance documentation is not a formality — it is the gate.
Compliance Documentation Checklist
Before purchasing drilling materials for European production, request:
- VOC test report (for UV-coated products)
- REACH compliance declaration (with substance list)
- RoHS test report (covering all 10 substances)
- MSDS (Material Safety Data Sheet)
- ISO 9001 certificate (factory-level)
- SGS test report (third-party verification, if available)
If a supplier cannot provide these documents, the risk is yours. See our certifications page for YUESHAN's compliance documentation.
