Gel-Pak Vacuum Release™ (VR) Trays

This extremely versatile "pocketless" tray securely holds fragile devices including bare die during shipping, handling and processing. A detailed illustration of how the VR technology works can be found at "How to use VR Tray products."

VR Trays are ideal for:

  • Extremely fragile or thin devices
  • Handling bare die
  • No contact with edges or top surface of device
  • Handling device sizes (X,Y) ranging from 250 micron to 75mm
  • High-volume automated device Pick & Place applications
  • Manual unloading using Vacuum Pens

For devices smaller than 250 micron the NDT Tray should be used. For devices larger than 75mm, the Wafer/Large Format VR Plates should be used.

Choosing the Correct VR Tray

Choosing the right VR mesh size depends on the X, Y size of your device. To optimize offloading performance Gel-Pak provides a wide range of mesh geometries (16, 33, 76, 103, 137, and 195) that can handle devices from 450mm down to 250 microns.

This chart illustrates the recommended mesh size as a function of device size (X, Y dimension).

Gel-Pak offers an online program that will calculate the recommended mesh size for your application, along with the maximum number of devices stored per tray. The number of devices per tray is dependent on tray size, die size, and required spacing.
