Engineered for Speed, Accuracy, and Stability
The WH389 delivers unmatched handling precision and consistent throughput in a high-mix production environment, with:
- +/- 30 µm, 3 Sigma placement accuracy
- High-precision ball-screw X/Y drive with rotary encoders
- Closed-loop servo control on all axes
- Rigid, vibration-dampening unibody steel frame
- Triple-head gantry for optimized parallel processing
- Up to 10,500 components per hour (IPC-9850)
Flexible Wafer & Die Handling Capabilities
Dual-vision alignment combines Cognex® on-the-fly and bottom stationary vision for fast, accurate die placement, wafer-level packaging, and micro-assembly. The WH389 includes:
- Ball inspection and missing ball detection
- Support for nonstandard and custom die layouts
- 23-position automatic tool changer with 17 standard nozzle types
Tooling & Feeder Adaptability
With a handling area of up to 650 mm x 460 mm (25.6" x 18.1"), the WH389 can be configured for a wide range of applications. The system accommodates:
- Up to 160 Smart Tape and Stick Feeders
- Wafer trays, gel packs, and waffle packs
- Feeder racks (front, back, and sides) with support for mixed formats
- Optional cut strip feeders and tray-based IC handling
Seamless Programming & Operation
The WH389 supports modern semiconductor workflows with:
- UCAD® (universal CAD) import from ASCII, AutoCAD, and Excel formats
- Onboard fiducial teaching camera
- Virtual PCB/IC Layout Simulator for verifying orientation and placement before production
- Smart Feeder compatibility for fast setup and efficient changeovers
Inspection & Inventory Tools
Enhance traceability and quality control with:
- Integrated vision inspection for die placement and paste printing
- Optional barcode scanning for lot codes, dates, and quantities
- Offline feeder programming to reduce downtime
