WHS Vacuum Wand – Stack Shipper Handling Tool (200 mm / 300 mm)

The WHS Stack Shipper Vacuum Wand is a precision-engineered tool designed specifically for safely loading and unloading thin, backgrinded, or fully processed wafers into stack shipping containers or single wafer coin shippers. Unlike conventional wafer handling tools, this wand features a larger contact ring at the vacuum tip to provide greater surface support, minimizing stress on fragile wafer substrates during transfer.

Built from high-purity aluminum, the wand offers excellent strength, rigidity, and long-term durability. All wafer-contacting surfaces are coated with inert Polyimide (Kapton®) to ensure ESD-safe handling and prevent any metallic contact with sensitive wafer surfaces. This non-metallic, anti-static coating is ideal for finished device wafers that are susceptible to damage from even low-level electrostatic discharge.

The angled tip design enhances operator ergonomics, making it easier to access wafers located at the bottom of stack shippers—a common challenge with traditional vacuum wands. The normally-open vacuum configuration ensures reliable pickup and release with consistent control.

Designed for use with 200mm and 300mm wafers, this complete system supports a wide range of substrate types, including:

• Ultra-thin backgrinded wafers
• Standard or thick bonded wafers
• Delicate processed device wafers ready for outbound shipment

The WHS Stack Shipper Vacuum Wand is fully antistatic and static-dissipative, with a built-in ground path that ensures safe discharge away from the wafer surface—protecting your product from unseen electrostatic threats during manual handling.
