The global electronics industry is one of the world’s biggest industrial sector. Most of the innovative products like portable devices, wearable electronics, and even self-driving vehicles and artificial intelligence enabled products are revolutionazing this industry in recent years. The number of customized products in the electronic manufacturing are increasing, profit margins are reducing, innovation cycles are reducing and time to the marketplace is fast-moving up. The necessity for modernized, well-organized and efficient operations has never been ever stronger and in the same arena the 4th Industrial revolution is under progress with the potential to take the efficiency of the electronics assembly industry to the next level. This paper is a case study of Industry 4.0 (I4.0) technologies in an Indian electronics sector and provides the deep insights on implementation of digital technologies in electronics parts manufacturing, its enablers, associated challenges and concludes with the leanings to adopt the digital technologies in the electronics parts manufacturing which can be a ready reckoner for its implementation to best deal with the deal with the challenges and take leverage of the potential opportunities, understand the key success factors by learning from real life examples. These learnings will help industries and enterprises to harness I4.0 in a methodical, accessible and effective manner.
