What Does Halogen-Free Mean for PCB/PCBA

  • PCBONLINE adopts two different lamination methods in multilayer ceramic PCB fabrication according to specific requirements.
  • Halogen-free PCB/PCBA manufacturing process has no difference with other PCB/PCBA manufacturing but only the strict halogen-free management to materials and manufacturing process. Halogens refer to fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogen-free requires PCBs, PCBA, wires, mechanical plastic parts, etc, to have less than 900 PPM of Cl or Br and less than 1500 PPM of total halogens.
  • PCB halogen-free is not part of the REACH or RoHS directive and it is not mandatory. But halogen-free is a trend towards the green initiative. And now more and more regulations release for banning halogen printed circuit boards and products. For instance, in the UK and many USA states, most halogen lamps have been banned from selling.
  • PCB halogen-free requires the PCB laminates to use the phosphorus (P) and/or nitrogen (N)-based flame retardant to replace the halogen-based flame retardant.

PCB Halogen-Free Measurements from PCBONLINE

halogen-free PCB material
Halogen-free involves a wide range of aspects, not only materials but also the production process. PCBONLINE processes halogen-free PCB/PCBA production in the following aspects:
Raw material supply - only by meeting PCBONLINE's strategy and product service requirements, can the raw material suppliers become qualified for us.
Electronic components procurement - the purchasing department is required to note all halogen-free materials when placing orders, and the products must meet the halogen-free PCB legislation. Meanwhile, PCBONLINE will provide customers with the RoHS and halogen-free SGS test report and MSDS composition list.
PCB/PCBA materials - all halogen-free PCB materials sent by suppliers must be labeled with halogen-free labels, and we will confirm the supplier's certificate of conformity (COC). In addition, every batch of raw materials must be tested for halogen-free environmental protection.
PCB/PCBA warehousing - we divide the storage area of halogen-free PCB laminate and halogen-free materials to prevent mixing.
PCB/PCBA production - each halogen-free PCB/PCBA order must be produced separately, and we divide different areas for different production processes. Materials in production areas must be separated to prevent mixing.
Packaging - we label according to the customer's requirements if there are any. If there are no extra packaging requirements, we label "HF" in the outer box.

Advantages of the Halogen-Free PCBs

  • Compared with halogen-based PCBs, halogen-free PCBs have these advantages:
  • Environment-friendly. When exposed to fire or recycled, halogen-free PCBs don't release toxic smoke.
  • Lower thermal expansion coefficients (CTE), longer T-260/288 (time for delamination), and higher thermal decomposition temperature (Td).
  • Lower water absorption and better thermal stability than halogen-based PCB due to the nitrogen-phosphorus redox resin.
