  • Gel-Pak®, a division of Delphon and leading manufacturer of device carriers will showcase its innovative products designed to safely handle compound semiconductors for 5G applications at Semicon West in San Francisco, CA

    The move toward 5G has created a greater need for high-speed, high-efficiency compound semiconductors. Materials used to create these high power devices often include Gallium Arsenide (GaAs), Gallium Nitride (GaN) and Indium Phosphide (InP).  These materials tend to be brittle which means greater care needs be taken when handling them. Gel-Pak’s unique ability to immobilize these fragile components ensures they will remain free from damage during transport.  The company’s ample assortment of product configurations and ability to customize device carriers for specific applications make Gel-Pak an ideal choice for compound semiconductor


    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

  • UltraTape, a division of Delphon and leading supplier of cleanroom tape, custom labels and graphic overlays, offers ESD Tapes to protect electronic components.

    Nearly 10% of electronic part failures are due to static charges.  Some of these failures arise from insulators such as masking tapes used in manufacturing processes.   UltraTape ESD tapes protect static sensitive components from electro static discharge. The tapes comply with the low charging and static dissipative requirements of ANSI/ ESD S20.20, IEC 61340 and JEDEC JESD 625B, produce less than 100 volts with liner removal-and again when removed post process-and include static dissipative top surfaces with surface resistances of >105 and < 109 Ohms.

    UltraTape ESD tapes are available in amber and black polyimide plus white and clear polyester and include a variety of PSA thicknesses and low charging, antistatic liners


    Located in Wilsonville, Oregon, UltraTape, a division of Delphon, manufactures high quality cleanroom tapes, labels and graphic overlays for critical environments. The ISO certified company maintains a cleanroom manufacturing facility to assure particle-free and residue-free products that meet even the most stringent standards.  UltraTape specializes in material development in order to customize products to meet customer specifications.

    UltraTape’s Wafer Box Sealing Tapes are ideal for packaging and transporting wafer boxes....

  •  These low-density polyethylene tapes are low in halogens and leachable chlorides. Polyethylene film and acrylic adhesive minimize outgassing and offer good “clean peel” properties. The tapes also offer excellent chemical resistance and good conformability.

    UltraTape’s Wafer Box Sealing Tapes are available in two adhesion levels:

    UltraTape 1110 is designed specifically for sealing wafer shipping boxes as well as cleanroom packaging and bag sealing. It's specially formulated medium-high adhesive leaves no residue or ghosting on plastic boxes, even after prolonged storage. The tape contains extremely low levels of metals, halogens, and outgassing.

    Colors: White (WH), Red (RE), Yellow (YE), Blue (BL), Orange (OR), Green (GR), Clear (CL)

    UltraTape 1112 is similar to the 1110 product. It is for applications where a medium adhesion tape is preferred. The 1112 tape has the same adhesive system (but different ratio of ingredients) as the 1110 tape, and a medium density as opposed to a low density polyethylene backing. These properties make it suitable for general use in the cleanroom environment.

    Colors: White (WH), Red (RE), Yellow (YE), Green (GR), Clear (CL).

  • Gel-Pak Vacuum Release™ (VR) Trays
    This extremely versatile "pocketless" tray securely holds fragile devices including bare die during shipping, handling and processing....

    • Gel retention levels of XT, XL, X4 (X8 available in 16 & 33 mesh only) available to accommodate variations of device size, weight and surface roughness.
    • Mesh sizes 16, 33, 76, 103, 137, and 195 available based on device size. White, or Yellow color available based on mesh size.
    • VR Trays are manufactured using special Process B Gel material.
    • VR Trays available in black conductive polycarbonate (C) or transparent styrene (T).
    • 2" VR Trays are configured either in a hinged box (-02 style) or with lid and outer clip (-00B style). Hinged boxes available is various bottom/top configurations using transparent styrene (T), conductive black (C), and transparent antistatic (AS) materials. 2" Lid available in clear styrene (T), conductive black (C), and transparent antistatic (AS) materials.
    • A wide assortment of optional printed grid patterns readily available. Custom prints artwork (grids, company name, logo, etc) can be created upon request.
    • 4" VR Trays (VR-44) available only in the lid and clip configuration (-00B). 2" Lid available in clear styrene (T), conductive black (C), and transparent antistatic (AS) materials.
    • (-00B) style boxes require clip to secure the lid and tray combination.
  • Special Waffle Pack Lid for Thin Die Handling
    UltraTape offers an entire line of irradiated tapes that are specifically designed to be used in sterile and critical environments....

  • Shipping thin die in waffle packs presents a challenge for many companies. Thin devices packed in these chip trays have a tendency to move around within their pockets and can "escape" from their pockets during transport. The GPL-22C/93CB Lid prevents die from escaping by creating a seal over each waffle pack pocket during shipping and handling.

    To provide the ultimate protection for your device during shipping, handling and processing, use the Gel-Pak VR product line.

    Gel-Pak Vacuum Release (VR) carriers are extremely versatile "pocketless" trays that securely hold fragile devices in place during transport. VR carriers immobilize devices so that there is no edge or top surface contact.

    VR Trays are ideal for:

    • Extremely fragile or thin devices
    • No Contact with edges or top surface of device
    • High-volume automated device Pick and Place applications
