Senawang Industrial Areas: Manufacturing and Engineering Companies

onsemi: a manufacturing anchor

onsemi's current Seremban location page describes wafer fabrication as well as probe, assembly and test operations. The listed technologies include discrete semiconductor devices and surface-mount packages. Company documentation identifies its assembly/test address as Lot 122, Senawang Industrial Estate. onsemi's manufacturing profile, company-hosted address documentation.

The address document is historical, so it should not be used to claim a currently valid certification. The important distinction is that onsemi lists separate wafer-fabrication and assembly/test activities. These should not be illustrated as one continuous campus or all assigned to the Lot 122 address without further evidence.

Engineering and office presence

Seremban Engineering Berhad identifies its head office at Lot 1A–1C, Lorong Bunga Tanjung 1/3, Senawang Industrial Park. This is a verified current business address; it should remain clearly distinguished from the differently named Senawang Industrial Estate. Seremban Engineering's location page.

Careplus also lists its principal office in Senawang Industrial Estate. That supports company presence, but a corporate-office address alone cannot establish that every historical group factory or production line is operating. When assessing the local manufacturing base, the date and type of evidence matter as much as the company name. Careplus corporate information.

New development is a separate category

SPD Tech Valley adds a development story to the area, but future investments should not be presented as existing occupants. InvestNS's 28 August 2026 report describes Dunham-Bush's purchase agreement for approximately 32 acres there. It targets construction in the first quarter of 2027 and operations in the first quarter of 2028. As of this guide's October 2026 review, those remain future milestones. InvestNS announcement.

What should a business check?

Use the documented industrial activity as a starting point when investigating production, component supply, fabrication or maintenance premises. Then check the exact property: permitted use, process restrictions, utility demand, loading space, vehicle turning and the building's condition. A supplier business should also consider whether it needs customer qualification or specialised process controls before assuming proximity creates a commercial opportunity.

Ask for the estate name and full address before comparing listings. Link the result to your production flow rather than treating all Senawang properties as equivalent. For electronics and battery-related location research, continue to the Tuanku Jaafar and Sungai Gadut guide; for broader city geography, use the Seremban guide.
