White Paper: Durability Advantages of Mercury’s Modified Off-The-Shelf (MOTS) Product Approach

January 5, 2022

16min read time (2143 words)

The defense electronics market encompasses a significant range of environments — touching every corner of the globe and the atmosphere’s edge — from fixed installations with conditioned air environments, to mobile deployment in extreme temperature environments.
This paper describes Mercury’s approach to building products for enhanced durability under extreme environmental conditions, including repeated temperature cycling over wide temperature ranges. Learn ruggedization design practices, risk mitigations, and Mercury's best-in-class set of design rules and manufacturing process called modified off-the-shelf (MOTS).

Read this white paper to learn:

Mercury's MOTS service that deliver products built and manufactured to provide extreme durability
Best practices: MOTS mechanical attachment and solder joint integrity
Best practices: Component underfill for thermal cycling
Best practices: Gold Embrittlement challenges and soldering
Best practices: Tin whisker mitigation to minimize use of lead without degrading system performance
DFN/QFN Packages challenges
Management of vented packages
Levels of MOTS+ ruggedization
