FR-2 PCB Laminates

FR-2 or Flame Retardant 2 is the NEMA designation for Synthetic Resin Bonded paper made up of phenol formaldehyde resin which is used as Printed Circuit Board Laminates having a glass transition temperature as high as 105 Degrees.

They provide excellent electrical and mechanical properties to the PCB and are relatively cheaper than other PCB’s which is the major reason for the major usage of FR-2 laminates in construction of PCB material. They are widely used for manufacturing low end consumer electronic equipments on the PCB board.

FR-2 laminates are used extensively used in PCB’s to provide superior heat resistance and smooth surface finish to the board. They are highly durable as compared to other laminates. When compared to FR-4 (the most commonly used PCB laminate), FR-2 has a slightly lower Tg of 105 Degrees and is not as efficient.

Also, it is very similar to FR-1, except for a lower glass transition temperature Tg of 105 degress, compared to 130 degress for FR-1. Many PCB manufacturers only provide one: FR-1 or FR-2 laminates as options for PCB boards and not both, as they are very similar.
