What are the Fabrication Guidelines for Arlon 85N?

Processo de fabricação de PCB

Fabricação de PCB

You should use the following process conditions when fabricating PCB made from Arlon 85N laminate.

  • You should use standard industry practices when processing inner-layers, that is, develop, etch, and strip.
  • Apply brown oxides on inner layers
  • Ensure uniform coating by adjusting dwell time in the oxide bath
  • Subject the inner layer to temperatures between 107°C to 121°C for 60 seconds in a rack when baking. You should do this immediately before lay-up.
  • You should desiccate the prepreg in a vacuum for 8 to 12 hours before lamination
  • When conducting lamination, please observe the following operational recommendations:
  • Perform pre-vacuum for between 30 to 45 minutes
  • Ensure that you set the heat rise to between 4°C and 6°C per minute for temperatures between 65°C to 121°C.
  • The process temperature at the initiation of cure should be 218°C.
  • Cure time at temperature should equalize two hours, depending on the stack height and copper quantity.
  • Use a controlled pressurized cooling system at ≤ 6°C/min
  • Maintain a drill speed between 400 to 500 SFM. You can use undercut bits for vias less than or equal to 0.045cm.
  • Use alkaline permanganate or plasma that has been set appropriately for polyimide. However, plasma deliver better results for positive etchback
  • You can use standard conventional plating processes for Arlon 85N since they are compatible.
  • Avoid using chip breaker style router bits. Other parameters for profiling will work well.
  • Subject the material to 121°C for 1 to 2 hours for baking just before soldering to reflow of HASL

Can you use Arlon 85N for High-Performance Applications?

Yes, Arlon 85N laminate is a pure polyimide resin system ideal for high-performance applications for use in high-temperature end-use products.

What Is the Use of Ceramic Fillers in Arlon 85N Laminate?

Arlon 85N is composed of a pure polyimide resins system even though you can add 30% or more ceramic filler content to create Arlon 84N.

The addition of ceramic filler enhances the material’s resistance to crack formation and shrinkage in filled clearance areas during drilling.

Is Arlon 85N RoHS Compliant?

Yes, Arlon 85N is RoHS compliant. Arlon 85N meets the requirements of the European Union’s Directive 2002/95/EC.

A more recent directive, RoHS 3 (European Union Directive 2015/863) was described in 2015 and became operational in July 2019.

It added four more elements to the initial list of six.

The RoHS compliant PCBs are sometimes referred to as lead-free PCBs because the directives are concentrated around lead and poly-brominates.

The directive restricts the use of selected hazardous materials in fabricating PCBs for use in electrical and electronic equipment.

Consequently, Arlon 85N PCBs does not exceed the limits allowed for the following elements:

Elements Permissible values (parts per million)

  • Lead <1000 ppm
  • Cadmium <100   ppm
  • Mercury <1000 ppm
  • Polybrominated biphenyls <1000 ppm
  • Cromo hexavalente <1000 ppm
  • Polybrominated diphenyl ether <1000 ppm
  • Di-isobutyl phthalate <1000 ppm
  • Dibutil ftalato <1000 ppm
  • Butyl benzyl phthalate <1000 ppm
  • Bis (2-ethylhexyl)- phthalate <1000 ppm

These directives help protect the environment because the products operating the PCBs will end up in landfills and other reclamation processes.

The directive also protects workers who produce the PCBs from occupational exposure to these carcinogenic elements.

What Factors Determine the Cost of Arlon 85N Material?
