Client Background
A Korean-invested EMS manufacturer in Bac Ninh, northern Vietnam, was building a 2,000 m2 assembly and burn-in area designed to ISO 14644-1 Class 8. The planned go-live was tied to an end-customer product launch, leaving little room for procurement delays.
The Challenges
- Available European HEPA options had lead times beyond the ramp-up window.
- Filters, equipment, and ESD items were being quoted by separate local vendors with inconsistent specifications.
- The procurement team needed support matching airflow, filter grades, and equipment dimensions across the project scope.
The WISHE Solution
- H13 HEPA filters with individual scan-test reports.
- F5-F8 medium-efficiency box filters for AHU pre-filtration stages.
- SS304 air showers and dynamic pass boxes with electronic interlocks.
- FFU units with EC fans for the ceiling grid.
- Ionizing bars and ESD garments, gloves, and shoes for static-sensitive assembly stations.
- Consolidated shipping to Hai Phong, with English and Vietnamese installation guides and scheduled video support during commissioning.
Results
Validation note: The following performance indicators are from the supplied project draft and should be checked against project records before external use.
- The project brief records production-area release five weeks after purchase order, ahead of the original procurement schedule.
- The supplied comparison records lower total procurement cost than the consolidated European quotation.
- The brief records first-pass completion of the end-customer cleanroom and ESD audit with batch test reports included in the qualification file.
