BANNOCKBURN, IL – IPC has announced the release of "J" revisions for two standards often used together for the manufacture of electronic assemblies.

IPC J-STD-001J, Requirements for Soldered Electrical and Electronic Assemblies is recognized as the sole industry-consensus standard for soldering processes and materials and IPC-A-610J, Acceptability of Electronic Assemblies, is a post-assembly acceptance standard used to ensure electronic assemblies meet acceptance requirements for the electronics industry.

Revisions to these standards are completed every three years, with significant changes made to each one. Clear guidance on the use of the standard can be found in the first chapter of each document. Committee leaders addressed more than 1,350 comments for revision “J.”

Some of the significant changes found in the standards are as follows:

• Global changes implemented in both documents:
  • Removed redundant minimum electrical clearance references – covered in Chapter 1 of documents
  • Clarified the use and definition of wire, lead and conductor
• Changes to IPC J-STD-001J:
  • Added hardware installation requirements
  • Added graphics to address bubbles in x-ray images
• Changes to IPC-A-610J:
  • Chapter 10 has new images
  • Conformal coating – clarified voiding/bubbles

In addition to the new revisions for IPC J-STD-001J and IPC-A-610J, redline documents are also available. A white paper is available IPC-WP-028, Guidance on Objective Evidence for Validating the Acceptability of Bubbles in Conformal Coatings.
