Flux Classification – Part 1: Interpretation of J-STD-001 and J-STD-004 Regarding Fluxes

J-STD-001 “Requirements for Soldered Electrical and Electronic Assemblies” and J-STD-004 “Requirements for Soldering Fluxes” are two critical industry documents for interpreting and classifying fluxes used in any soldering process.

This webinar will provide a brief view of fluxes from the perspective of:

  • Material and Process Nonconformance
  • Material Requirements
  • Flux Requirements
  • Flux Identification


If you build product to Class 3 specification, this information is vital to your understanding of how flux classification can impact an audit of your process.
