🧠 Why Electronics Uses So Many Acronyms
Electronics sits at the intersection of:

• Semiconductor physics
• Hardware design
• Automated manufacturing
• Global component sourcing
• High-volume consumer markets

Because PCB design, assembly, and supply chains must coordinate precisely, acronyms became a standardized “working language” across OEMs, EMS providers, and suppliers
 
​Hope you notice some of the previous  acronyms are common in other fields Tech companies have hundreds of these.
