Overview
Ueno Seiki makes back-end handling equipment. Its test handlers carry packaged devices to the tester and sort them by result, and its taping machines pack them into carrier tape for shipment.
Visual inspection systems check package appearance, so the company covers the steps from test to packing for small packages handled at high speed.
Business: Test handlers, taping machines and visual inspection systems
Why it matters
- For small discrete and analog devices, handler throughput rather than tester speed often limits test cost.
- Combining test handling, inspection and taping in one line reduces handling between steps.
