Gel-Pak Showcases Carriers For Compound Semiconductor Devices

HAYWARD, CA, MAY 1, 2018. Gel-Pak®, a division of Delphon and leading manufacturer of device carriers, designed a custom Vacuum Release Tray TM (VR Tray) to ship fragile Planar Lightwave Circuits (PLC).

One of the world’s largest photonic component manufacturers needed to safely ship and handle large volumes of highly polished Planar Lightwave Circuit devices. The silicone photonic device was extremely fragile and it was important that it remain free from scratches during handling. Gel-Pak worked with the customer to develop a solution that involved a specially-sized Vacuum Release Tray (VR). Gel-Pak’s VR product line features a Gel membrane over a mesh material that effectively immobilizes components until vacuum is applied to the underside of the tray. In this case, the customer was provided a large format VR product with a customized print grid used for tracking each individual PLC device. The customer implemented this solution to ship and handling this fragile component without any yield loss.


Founded in 1980, Gel-Pak has developed a line of proprietary gel and polymer coated device carriers and handling materials that offer solutions for applications where damage during handling must be avoided. The company’s unique elastomer technology serves as the basis of its Gel-Box™, Gel-Tray®, Gel-Film®, and patented Vacuum Release products. These products effectively immobilize devices during shipping and handling. For further information on Gel-Pak’s product line, please refer to the website at
