In the past two years, more polymers have been committed to the upgrade of "anti-static tray" (ESD tray) products in order to replace the existing hollow board lamination foam tray (ESD PE foam tray) to better serve PCBA manufacturers. . In October 2021, the new product ESD foam tray completed the product test, and successfully delivered the first order in December 2021, with good feedback from users. Compared with the previous products, the biggest advantages are: lighter weight; scratch resistance, rubbing resistance; no smell, high production efficiency. And because the ESD foam tray adopts a one-step molding process, the tray has no seams, will not crack, and is not easily deformed. It also performs better than the previous generation of ESD foam trays in terms of time and frequency of use.

Reinforced anti-static corrugated boxes, trays and dividers can not only be customized as ordinary anti-static products, but also are more robust, more durable and better impact-proof.

Project Background Our client, a leading manufacturer in the semiconductor and server industry, was looking for a tailored packaging solution for internal factory circulation. The packaging needed to be durable, anti-static, shock-resistant, compression-resistant, cost-efficient in logistics, and reusable. Customer Requirements During daily PCBA circulation, the client wanted packaging that could: · Provide stronger load-bearing performance for heavier assemblies. · Allow more compartments while keeping dividers as slim as possible to maximize space utilization. · Ensure stable anti-static performance for sensitive PCBA components. · Be efficient in transportation, with secure stacking and reusable design. YUFA Polymer Solution We developed a custom ESD honeycomb box using 4mm anti-static honeycomb sheets (1200g/m²). · Box Dimensions: 400 × 300 × 220 mm · Internal Structure: 48 compartments with a single-layer divider design · Capacity & Strength: Load capacity up to 30 kg, providing enhanced protection for PCBA assemblies · Material Properties: Black, permanent ESD (surface resistance: 10⁴–10⁹ Ω) · Stackability: Designed to be stackable with or without lid · Production & Delivery: 100 units, completed within 7 days Results & Customer Feedback · Performance: The solution delivered improved load capacity, reliable anti-static protection, and effective compartmentalization. · Transportation: Each box was packed with pallet + EPE foam + stretch film, ensuring safe delivery with zero damage. · Customer Satisfaction: The client recognized the thoughtful design, which balanced durability and space efficiency. They expressed strong satisfaction and confirmed plans for repeat orders.

1. Client Background A client from the semiconductor industry required specialized packaging for PCB assemblies (PCBA) used in their production line. Their products are highly sensitive to static electricity and electromagnetic interference, and reliable packaging was essential to prevent ESD-related failures. 2. Customer Challenge Previously, the client used general anti-static bags, which offered basic static protection but lacked effective shielding against electromagnetic discharge. This resulted in: · Higher risk of ESD damage during transportation. · Limited durability for repeated use. · Increased costs due to frequent replacement. 3. Our Solution Yufa Polymer designed a custom metallic shielding bag with the following specifications: · Material structure: PET + Aluminum metallization + CPP/PE + Anti-static coating. · Shielding effectiveness: <50 nJ. · Static decay: <2 seconds. · Surface resistance: 10⁸–10¹¹ Ω. · Custom dimensions: optimized for the client’s PCBA trays, ensuring secure fit. · Thickness: 0.075 mm ±10%, with strong heat-sealed edges for durability. 4. Delivery & Implementation · Order quantity: 50,000 pcs. · Thickness: 3 mil · Lead time: 10 days. · Packaging: packed with protective carton + moisture barrier to ensure safe delivery. The bags were delivered on schedule and immediately put into use in the client’s factory for in-house circulation and export shipments. 5. Client Feedback The client confirmed that: · The new ESD shielding bag significantly reduced static failures in transit. · Durability exceeded expectations, allowing multiple reuse cycles. · Shielding performance was consistent with international standards. They have since placed repeat orders and expanded the application of our anti-static bag solutions to other electronic components. �� Why This Matters This case demonstrates how OEM ESD packaging solutions can directly address customer pain points — from static protection to cost efficiency. At Yufa Polymer, we not only manufacture metallic shielding bags, but also provide custom design and rapid delivery to meet industry-specific demands. �� Contact us to learn more about OEM & custom anti-static packaging solutions.
