An electronic engineer asked a senior in the military industry: “I heard that military-grade circuit boards are the most difficult, is that true?”
To his surprise, the military expert replied: “Actually, it’s not that difficult; the key is to get EMC and EMI right.”
This left the questioner astonished—”Isn’t it difficult to get EMC and EMI right?”
The military industry veteran further explained:
“Military design is fundamentally consistent; analog and digital electronics are the basics. The core characteristic of military products is that all design requirements must be ‘visible and tangible’; every data result must have a corresponding formula as a basis for calculation. For example, regarding voltage deviation, military design must clearly answer: how much is the deviation? What is the floating frequency? These all require precise calculation and verification.”
The engineer who asked the question expressed that if he could participate in military-grade work, even for just a year, he would definitely learn a lot, “Whether my salary increases or not is irrelevant; the main thing is to learn.”
This attitude was recognized by the military veteran.
In fact, military electronic design can indeed foster an extremely rigorous engineering mindset, as every design decision must be supported by theory and experimental validation.
Military circuit boards do have higher requirements compared to commercial products, mainly reflected in:
1. Reliability: Must operate stably in extreme environments.
2. Traceability: Every design choice must have a theoretical basis.
3. Verifiability: All parameters must be measurable and verifiable.
4. Consistency: The performance of mass-produced products must be highly consistent.
However, military design is not shrouded in mystery; as long as one masters the core EMC/EMI design principles and possesses a solid foundation in analog and digital circuits, one can be competent in military-grade circuit design.
The “high difficulty” of military products is more reflected in the rigor of the design process and the comprehensiveness of verification, rather than the use of any mysterious technology.
