Semiconductor devices - Mechanical and climatic test methods -- Part 20-1: Handling, packing, labelling and shipping of surface mount devices sensitive to the combined effect of moisture and soldering heat

| Status: | inactive |

| ICS Code (Semiconductor devices in general): | 31.080.01 |
scope:
This part of IEC 60749 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 drybags from the seal date.
NOTE: Hermetic SMD packages are not moisture sensitive and do not require moisture precautionary handling.
