Custom Halogen-Free PCB
Huayihai fabricates custom halogen-free PCBs using laminates that avoid brominated and chlorinated flame retardants. Halogen-free construction is specified by customers with environmental, recycling, or restricted-substance requirements, and by products sold into markets that restrict halogenated materials.
Halogen-free laminates are processed like standard FR-4 in terms of layer count and finish options, but with adjusted drilling and lamination parameters. Huayihai offers halogen-free material alongside FR-4, Hi-Tg, Rogers, and hybrid stack-ups, and operates under RoHS and REACH compliance, IPC-A-600 workmanship standards, and ISO 14001 environmental management.
Custom Manufacturing Only
We fabricate halogen-free PCBs according to customer Gerber files and technical specifications. We do not supply ready-made or standard stock boards.

Key Features
- Laminates free of brominated and chlorinated flame retardants
- RoHS and REACH compliant production
- Available on 2 to 64 layer stack-ups
- Lead-free surface finishes including ENIG and lead-free HASL
- ISO 14001 environmental management
- Manufactured under IPC-A-600 workmanship standards
Manufacturing Highlights
Halogen-free laminates behave differently in drilling and lamination compared with conventional FR-4, so process parameters are tuned per material. Huayihai matches material choice to the customer's compliance requirement and verifies the finished board through electrical and reliability testing.
Key fabrication elements include:
- Material and stack-up review of Gerber files
- Drilling and lamination parameters adjusted for halogen-free laminate
- Lead-free surface finishes (ENIG, lead-free HASL, Im Sn, Im Ag, OSP)
- Reliability testing including environmental and thermal testing
- 100% electrical testing before shipment

FAQ
Q1: What makes a PCB halogen-free?
The laminate avoids brominated and chlorinated flame retardants, which are restricted by some environmental and recycling requirements.
Q2: Is halogen-free material harder to process?
It requires adjusted drilling and lamination parameters, which Huayihai applies per material.
Q3: Are halogen-free boards RoHS and REACH compliant?
Yes, production operates under RoHS and REACH compliance.
Q4: What surface finishes are available?
Lead-free HASL, ENIG, Im Sn, Im Ag, and OSP.
Q5: What is the standard lead time?
3–5 working days for PCB prototypes and batches, after file review is complete.
Q6: Can halogen-free PCBs be manufactured with ENIG?
Yes. ENIG is available for halogen-free PCBs when specified.
Q7: Do halogen-free boards support multilayer construction?
Yes. Halogen-free materials are available for 2–64 layer PCB fabrication according to customer requirements.
