68 SMT007 MAGAZINE I NOVEMBER 2021 Feature Article by Jonathon Vermillion BALL AEROSPACE One of the most frequent questions I was asked during the last year was about the biggest changes in revision H of the IPC J-STD-001 Re- quirements for Soldered Electrical and Elec- tronic Assemblies. e J-STD-001 is the mate- rial and process requirements used for manu- facturing of electronic assemblies. e latest revision of the J-Standard was mostly completed online with working group meetings. ere were more than 1,700 com- ments submitted to the H revision, including those from the IPC-A-610 Task Group.
