Gel-Pak Vacuum Release™ (VR) Trays - (VR, VRP, VRV Series)
This extremely versatile "pocketless" tray securely holds fragile devices including bare die during shipping, handling and processing. It is ideal for high-volume pick and place applications.
The surface of the VR carrier uses a proprietary Gel or non-silicone Vertec™ film membrane over a mesh material to hold components in place until they are released by applying vacuum to the underside of the tray.
