Course Overview for Handling Moisture Sensitive Components (Standard for Handling, Packing, Shipping and Use of Moisture / Reflow Sensitive Surface Mount Devices)
Why This Training Matters
Electrostatic discharge and moisture sensitivity are two of the most common causes of component failure in electronics manufacturing. While ESD awareness programs address electrostatic damage, this program specifically addresses moisture-induced damage a distinct but equally critical reliability threat. By understanding and implementing the requirements of IPC/JEDEC standards, manufacturers can significantly reduce production losses, improve product quality, enhance field reliability, and increase customer satisfaction.
This training is an essential investment for any organization involved in surface mount assembly, particularly those working with fine-pitch, high-density, and high-reliability electronic products.
This 2-day training program is designed to equip manufacturing specialists with the technical knowledge and practical skills required to properly handle, package, ship, and use moisture/reflow sensitive surface mount devices.
Moisture sensitivity is a critical issue in electronics manufacturing.
When surface mount devices absorb moisture from the environment and are subsequently exposed to the high temperatures of reflow soldering, the rapid vaporization of trapped moisture can cause internal cracking, delamination, popcorning, and complete component failure.
These failures can occur during production or manifest later as field failures, leading to costly recalls, reduced reliability, and damaged customer relationships.
This training program provides a comprehensive understanding of the science behind moisture damage, the industry standards that govern classification and handling, and the practical procedures needed to prevent moisture-related failures in day-to-day manufacturing operations.
Upon completion of this program, participants will be able to:
- Understand the physics and mechanisms of moisture damage in surface mount devices
- Classify components according to IPC/JEDEC J-STD-020 moisture sensitivity levels
- Apply IPC J-STD-033 requirements for handling, packing, shipping, and use
- Implement proper storage, baking, and floor life control procedures
- Utilize IPC-9501 through IPC-9504 for preconditioning and process simulation
- Develop and maintain an effective moisture control program
- Train personnel in moisture-sensitive component handling
- Reduce moisture-related failures and improve product reliability
