Multilayer PCB ROHS
$49.90
Multilayer PCB ROHS refers to the circuit board with multiple copper layers that comply with ROHS (Restriction of Hazardous Substances) to restrict the use of lead and other hazardous materials like mercury, cadmium. It is prevalent in consumer electronics, aerospace, industrial IoT, and other industries.

Questions & Answers
1. What’s your shipping port?
We ship the goods via the Port of Hong Kong or Shenzhen.
2. Why choose RoHS-compliant multilayer PCBs?
Multilayer PCB ROHS has better reliability and thermal resistance because it eliminates hazardous substances like lead and mercury. On the other hand, ROHS improves marketability because it is important for the global market, especially the EU and the US, to avoid legal issues.
3. Does RoHS compliance affect performance?
Not significantly. Lead-free solders are stronger in handling higher temperatures and reduce toxic risks, but they need thermal profiling. The compatible material ensures signal integrity and durability, making it a wise choice.
4. What’s the max layer count for a RoHS PCB?
The standard layer is 4-12 layers, and the advanced PCB, like HDI, can be made up to 50+ layers. MOKOPCB is capable of manufacturing multilayers.
5. How do I identify a RoHS-compliant PCB?
You can look for “RoHS” or “Pb-Free” marking on components, verify supplier documentation, or test reports (XRF analysis) for hazardous material checks.
6. What are common RoHS-compliant surface finishes for multilayer PCBs?
The popular lead-free surface finishes include ENIG, ENEPIG, Immersion Silver, Immersion Tin, OSP, and Lead-free HASL. MOKOPCB provides all of those surface finishes. Contact our expert for details.
7. What certificates do you have?
MOKOPCB provides certificates of RoHS, ISO9001, ISO13485, IPC610, and UL.
8. Are RoHS-compliant PCBs recyclable?
Yes, RoHS-compliant PCBs are recyclable, but their recycling methods are slightly different from the traditional ones for their higher melting points. Common methods include shredding, smelting, and chemical leaching.
