MSD
MSD (Moisture Sensitive Device) is a term used in electronics manufacturing to describe electronic components that can be damaged by moisture in the air. Think of these components like cookies that go stale when exposed to air - they need special handling and storage. When these parts absorb moisture and then go through the high-heat soldering process, they can crack or fail, similar to how a closed soda can might explode when frozen. This is why manufacturers have specific rules about how long these parts can be out in the open air and how they must be stored in special sealed bags or cabinets with humidity control.
Examples in Resumes

Example Interview Questions
Senior Level Questions
Q: How would you set up an MSD control program in a new manufacturing facility?
Expected Answer: A strong answer should cover creating storage areas with humidity control, establishing handling procedures, training programs for staff, implementing tracking systems, and setting up emergency procedures for when moisture exposure occurs.
Q: What methods would you use to improve MSD handling efficiency without compromising safety?
Expected Answer: Should discuss streamlining processes, using barcode/tracking systems, organizing storage by sensitivity levels, and training strategies while maintaining strict moisture exposure controls.
Mid Level Questions
Q: How do you handle a situation where an MSD component has exceeded its floor life?
Expected Answer: Should explain the baking process to remove moisture, proper documentation procedures, and how to prevent similar situations in the future.
Q: Explain how you would train new employees about MSD handling?
Expected Answer: Should cover basic concepts of moisture sensitivity, proper handling procedures, storage requirements, and the importance of following exposure time limits.
Junior Level Questions
Q: What information do you need to check on an MSD component before using it?
Expected Answer: Should mention checking the moisture sensitivity level, maximum floor life, current exposure time, and proper storage conditions.
Q: Why is it important to handle MSD components carefully?
Expected Answer: Should explain that moisture can damage components during soldering, leading to product failures and waste of expensive parts.
