What it means for Penang
This plant is in Selangor, so it does not add jobs in Penang directly. It matters because it shows where the electronics supply chain is heading:
- AI hardware is driving factory investment. Copper foil goes into the circuit boards and chip substrates that Penang’s electronics factories assemble and test.
- Industrial land and buildings are a big cost. About RM1.18 billion of this project is for land and buildings alone.
- For homebuyers, jobs follow factories. In Penang, the same trend shows up in Batu Kawan and Bayan Lepas. See our reports on the Eppendorf plant in Bandar Cassia and the Penang industrial forum.
