Overview
The Gel-Pak GP-CLIP-22C and GP-CLIP-22C-M are precision-engineered conductive snap closure clips designed specifically for secure mechanical retention of 2-inch vacuum release (VR) trays and their corresponding lids during handling, storage, and logistics in semiconductor fabrication and packaging environments. These clips operate on a passive mechanical principle—leveraging controlled elastic deformation of conductive polypropylene to generate consistent clamping force without fasteners, adhesives, or external power. Unlike generic plastic retainers, the GP-CLIP series is formulated to meet stringent electrostatic discharge (ESD) control requirements defined under ANSI/ESD S20.20, ensuring compatibility with Class 0–Class 1A ESD-sensitive device workflows. Their integration supports industry-standard Gel-Pak VR tray systems—including Gel-Box™ and Gel-Tray® platforms—where reliable lid-to-tray sealing prevents unintended separation, particulate ingress, and mechanical shock-induced die displacement during transit or automated material handling.
Key Features
- Conductive black polypropylene construction with surface resistivity spanning 10³–10⁶ Ω, enabling charge dissipation while maintaining mechanical integrity
- Optimized snap-fit geometry for repeatable, tool-free installation and removal on standard 2-inch VR trays (e.g., Gel-Pak GP-VR-200 series)
- Thermal stability up to 85 °C, supporting compatibility with cleanroom-compatible bake-out protocols and humidity-controlled storage environments
- Non-marring, low-particulate design—validated per ISO 14644-1 Class 5 cleanroom requirements for use in front-end and back-end semiconductor facilities
- RoHS-compliant formulation with no halogenated flame retardants, aligning with JEDEC J-STD-033 and IPC-1752A material declaration standards
- Dual variant availability: GP-CLIP-22C (standard retention force), GP-CLIP-22C-M (modified engagement profile for high-vibration transport scenarios)
Sample Compatibility & Compliance
These clips are dimensionally calibrated for use with Gel-Pak’s 2-inch vacuum release tray family, including but not limited to GP-VR-200, GP-VR-200L, and GP-VR-200S configurations. They interface exclusively with trays featuring standardized perimeter flange geometry and lid alignment pins per Gel-Pak Mechanical Interface Specification Rev. 4.2. The conductive polymer matrix complies with ANSI/ESD S20.20 for personnel grounding system integration and meets IEC 61340-5-1 requirements for protected area implementation. No regulatory certification (e.g., UL, CE) applies, as the product is classified as a passive mechanical component under SEMI E10-0218 equipment classification guidelines. It is not intended for direct wafer contact nor for use in vacuum chamber internal applications.
Software & Data Management
As a purely mechanical retention component, the GP-CLIP-22C and GP-CLIP-22C-M require no firmware, embedded logic, or software integration. However, they are fully compatible with traceability workflows governed by SEMI E142 (Equipment Data Acquisition) and support audit-ready documentation when deployed within MES-integrated packaging lines. Batch lot numbers and material certifications (including UL94 HB flammability rating and ASTM D257 surface resistivity test reports) are supplied with each shipment and can be linked to ERP systems via GS1-128 barcodes on secondary packaging. Full material declarations (IMDS and IPC-1752A XML format) are available upon request for supply chain compliance reporting.
Applications
- Securing lid-to-tray interfaces in automated wafer sort and probe stations prior to electrical testing
- Stabilizing 2-inch compound semiconductor substrates (GaAs, SiC, GaN) during air freight and inter-fab transfer
- Enabling repeatable handling of MEMS devices, RF filters, and optoelectronic components housed in Gel-Pak VR trays
- Supporting ISO/IEC 17025-accredited calibration labs requiring documented ESD-safe packaging for reference standards transport
- Integration into GMP-aligned packaging lines for medical-grade semiconductor sensors under FDA 21 CFR Part 820 traceability mandates
FAQ
Are GP-CLIP-22C clips reusable?
Yes—designed for ≥500 cycles of installation/removal without loss of retention force, provided clips are not exposed to solvents or UV degradation beyond specified limits.
Do these clips meet JEDEC J-STD-033 moisture sensitivity level (MSL) requirements?
No—they are not moisture barrier components; MSL compliance is achieved at the tray-and-lid assembly level, not the clip itself.
Can GP-CLIP-22C-M be substituted for GP-CLIP-22C in all applications?
GP-CLIP-22C-M features higher initial insertion force and reduced creep under sustained load; substitution requires validation against tray flange tolerances per Gel-Pak TIR-2023-007.
Is cleaning required before first use in Class 10 cleanrooms?
Yes—recommended pre-use cleaning includes vapor degreasing with ultra-pure isopropyl alcohol (IPA) followed by nitrogen purge, per SEMI F21-0217.
What is the shelf life under ambient warehouse conditions?
Five years from date of manufacture when stored sealed in original packaging at 23 ± 5 °C and <60% RH, per ASTM D4329 accelerated aging protocol.
