Document classifies worst-case thermal process limitations.September 10, 2008 -
Developed jointly by IPC, JEDEC, and ECA, J-STD-075, "Classification of Non-IC Electronic Components for Assembly Processes" expands on existing standards to provide test methods and classification levels to identify worst-case thermal process limitations for all electronic components that may be processed as part of circuit card assembly. Additionally, J-STD-075 includes classification categories to identify cleaning process sensitivity.

BANNOCKBURN, Ill., USA, September 5, 2008 - IPC - Association Connecting Electronics Industries® announces the release of J-STD-075, Classification of Non-IC Electronic Components for Assembly Processes. Developed jointly by IPC, JEDEC and ECA (Electronic Components Association), this new document expands on existing standards to provide test methods and classification levels to identify the worst-case thermal process limitations for all electronic components that may be processed as part of a circuit card assembly, including passives, connectors, switches and other devices.
"Users have long been struggling with component damage that occurs during processing," said Jack Crawford, IPC director of certification & assembly technology. "J-STD-075 provides classifications to cover the increased preheat, reflow or wave soldering temperatures that can cause components to melt, warp, crack, delaminate or even explode. Another potential source of damage involves cleaning processes."
According to Crawford, J-STD-020, Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Devices is limited to moisture-related issues of nonhermetic integrated circuits. "The new standard expands the coverage to all components," he adds.
Additionally, J-STD-075 includes classification categories to identify cleaning process sensitivity. There is also a wild-card option that component manufacturers can use to identify process issues not covered by this standard. J-STD-075 references the packaging and labeling requirements of J-STD-033, Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices. J-STD-075 supersedes IPC-9503.
IPC member companies may request a free copy of J-STD-075 within 90 days of its publication. Following the introduction period, members may purchase a copy for $26. Nonmembers may purchase the new standard for $52. For more information on J-STD-075, visit the IPC online bookstore at ipc.org/onlinestore.
