BS EN 60749-20-1:2009

This standard BS EN 60749-20-1:2009 Semiconductor devices. Mechanical and climatic test methods is classified in these ICS categories:

• 31.080.01 Semiconductor devices in general

IEC 60749-20-1:2009 applies to all non-hermetic SMD packages which are subjected to reflow solder processes and which are exposed to the ambient air. The purpose of this document is to provide SMD manufacturers and users with standardized methods for handling, packing, shipping, and use of moisture/reflow sensitive SMDs which have been classified to the levels defined in IEC 60749-20. These methods are provided to avoid damage from moisture absorption and exposure to solder reflow temperatures that can result in yield and reliability degradation. By using these procedures, safe and damage-free reflow can be achieved, with the dry packing process, providing a minimum shelf life capability in sealed dry-bags from the seal date.
