An Amendment to JSTD-001 has been released by IPC

 

IPC J-STD-001G, Requirements for Soldered Electrical and Electronic Assemblies is recognized worldwide as the sole industry-consensus standard for soldering processes and materials. Section 8, Cleaning and Residue Requirements of the standard has been significantly changed with the release of IPC J-STD-001G-Am1. Of significance is where the use of the 1.56 μg/NaCI equivalence/cm2 value for Resistivity of Solvent Extract (ROSE), with no other supporting objective evidence, is not considered an acceptable basis for qualifying a manufacturing process.

The J-STD-001 committee formed a working group of subject matter experts to determine the “next generation” of ionic contamination requirements. The result of this working group is the release of IPC J-STD-001G-Am1, Requirements for Soldered Electrical and Electronic Assemblies Amendment 1. Included with this standard is IPC-WP-019A, An Overview on the Global Change in Ionic Cleanliness Requirements. The amendment provides the changes to Section 8 Cleaning and Residue Requirements and the white paper is provided to explain in detail the changes with additional language for clarity of the changes.

For many assemblies, ROSE testing is no longer a sufficient enough test regimen to predict acceptable levels of ionic residues. ROSE is to be used for “process control” and no longer used for “product acceptance”. Qualifying the solder and/or cleaning processes are a new requirement found in IPC J-STD-001G-Am1.

The committee fully understands the significance of the changes to the standard with the release of this amendment. Therefore, they have provided the white paper IPC-WP-19A which offers many examples of how both large and small companies can meet the new requirements of the IPC J-STD-001G-Am1.
