A Tier 1 optical component manufacturer needed a more reliable way to handle small EML laser devices used in next-generation optical systems. Conventional waffle pack carriers allowed components to move within the pockets, creating the potential for rotation, edge contact, and variation during automated pick-and-place. The engineering team needed a carrier that could stabilize high-value devices during handling and transport while maintaining consistent automated release and supporting future device-size changes. Why Device Migration Matters For small, high-value devices, the carrier is part of the automation interface. Even limited movement within a conventional pocket can change the position or orientation presented to the pickup tool. Devices can shift or rotate inside conventional waffle pack pockets. Movement can create edge contact, misalignment, or inconsistent pickup conditions. Handling variability can affect yield, cost, and production readiness. As device dimensions decrease, carrier stability becomes increasingly important. Solution Gel-Pak partnered with the manufacturer to validate WPX, a pocketless textured elastomer carrier platform optimized with EUL tack. Instead of relying on device-specific pocket walls, WPX stabilizes components directly at the carrier surface. The application-specific tack selection was intended to balance two operating requirements: maintain device position during handling and transport, then support consistent release during automated pick-and-place. Platform Design Pocketless Textured Surface Stabilizes the device at the contact surface rather than allowing the component to move within a mechanically oversized pocket. Application-Optimized EUL Tack Supports temporary retention while maintaining the release behavior required by automated handling equipment. Key Capabilities Textured surface immobilizes components Pocketless architecture that reduces dependence on device-specific cavity geometry Consistent presentation of the device to automated pick-and-place tools Zero die migration reported in the source case study Support for multiple device sizes within the evaluated application range A practical replacement path for existing waffle pack handling workflows Technology Innovation Traditional waffle packs organize devices using recessed cavities. The pocket must include clearance for loading and removal, but that same clearance can allow a small component to translate or rotate. WPX changes the retention mechanism by holding the component at the elastomer surface rather than depending on the pocket perimeter for positional control. Benefits of the WPX Design Conventional Waffle Pack Position depends on pocket geometry and clearance Movement or rotation can occur inside the cavity New device dimensions may require different pocket geometry Pickup conditions can vary with device position WPX Surface-Stabilization Approach Device is stabilized directly at the textured surface Reduced lateral movement and rotation risk Pocketless surface supports greater device-format flexibility More repeatable presentation to automated pickup equipment Development Process Gel-Pak and the customer conducted a structured production-relevant evaluation that included: Multiple evaluation lots Multiple device sizes Automated pick-and-place testing Drop testing Retention and release assessment Operator evaluation of the handling workflow Validation Results The customer reported successful technical validation across the evaluated lots and device sizes. The validation included successful pick-and-place and drop testing, supporting progression from evaluation toward early-stage adoption. Operator feedback indicated a strong preference for WPX compared with the existing waffle pack solution. Observed Performance Across Customer Evaluations Throughput: approximately 20–25% gain Pick time: approximately 0.5–1.5 second reduction per device OEE: approximately 15–20% improvement Yield: approximately 1–3% gain Business Impact By reducing device migration and orientation variability, WPX can help improve the consistency of the automated handling interface. For a high-value optical device, this supports a more stable path from qualification into production while reducing handling-related variability. Platform Advantage WPX is designed as a qualification-friendly replacement path for applications already using waffle pack carriers. The customer can preserve the familiar tray-based handling concept while changing the way the device is stabilized inside the carrier. Applications EML laser devices Optical transceiver components Photonic devices Small semiconductor die High-value components requiring stable automated handling New-product introduction and production qualification workflows Key Takeaway As device complexity and production volumes increase, manufacturers need handling solutions that reduce movement, protect yield, and support efficient automated workflows. WPX provides a practical path for customers seeking greater device stability without abandoning the familiar carrier-based handling concept.
