Introduction

We developed our Electrically Conductive PEI for IC Tray: a high-performance modified material crafted by blending high-quality conductive carbon fiber with premium PEI (Polyetherimide) via advanced twin-screw extrusion and precision granulation. Shaped into uniform black granules, this material is purpose-built for IC TRAY production.

Product Features

Our Electrically Conductive PEI compound isn't just a "one-size-fits-all" material-it's engineered with the specific needs of IC TRAY production in mind, drawing on years of hands-on experience in semiconductor packaging. Every feature is designed to solve real problems on the production floor and in end-use applications:

Dual Resistivity Grades for Versatile Needs:

We offer two resistivity options to match different IC TRAY requirements-conductive grade (surface resistivity ≤10⁶ Ω/sq) for direct static grounding (critical for high-sensitivity chips) and static dissipative grade (surface resistivity 10⁶–10¹² Ω/sq) for controlled static discharge. Both grades fully comply with JEDEC and ANSI/ESD S20.20 standards, effectively preventing static accumulation that can break down delicate IC components. This flexibility makes our conducting plastics PEI suitable for everything from standard DIP chip trays to high-precision BGA and FCBGA trays used in advanced packaging.

Exceptional High Flowability:

With a melt flow rate of 12g/10min (tested at 340℃, 5kg), our Conducting PEI outperforms most conductive PEI materials on the market. This isn't just a numbers game-it's a game-changer for IC TRAY production. IC TRAYs often have complex cavity structures, thin walls (as thin as 0.3mm in some cases), and fine pin slots that require full mold filling. Our material's high flowability ensures no underfilling, shrinkage, or warpage, boosting yield rates and reducing scrap-something we've seen firsthand cut production costs by 15–20% for our clients. It's especially valuable for high-precision trays where dimensional accuracy is non-negotiable.

Outstanding High-Temperature Resistance:

As a thermally conductive PEI, it boasts a continuous use temperature of up to 200°C, easily handling the high temperatures of reflow soldering (typically 180–260°C for short periods) and long-term storage in industrial environments. Unlike cheaper materials that soften or deform under heat, our thermally conductive PEI polymers maintain their shape and performance even after repeated exposure to high temperatures-critical for IC TRAYs used in SMT assembly lines and advanced packaging processes. We've tested it extensively in real-world conditions, and it consistently holds up without compromising conductivity or dimensional stability.

User-Friendly Processability:

We designed this Electrically Conductive PEI with production efficiency in mind-no special equipment or complex adjustments needed. It works seamlessly on standard injection molding machines used for IC TRAY production. The recommended drying condition is 150°C for 4 hours (a must to remove moisture, which causes bubbles, silver streaks, or conductivity drops during molding), and the processing temperature range is 340–370°C-compatible with most IC TRAY production lines. It also has excellent demolding properties, reducing mold sticking and speeding up cycle times-something every production manager appreciates.

Superior Dimensional Stability:

IC TRAYs require extreme precision (usually ±0.05mm or tighter) to ensure a perfect fit for IC chips-loose or warped trays cause jamming, damage, and costly delays. Our Conducting PEI excels here: the conductive carbon fiber reinforcement reduces shrinkage rate to ≤0.2%, far lower than ordinary conductive PEI, and provides excellent creep resistance. This means your IC TRAYs will maintain their shape and size accuracy even after repeated use, high-temperature exposure, and long-term storage-no more inconsistent fits or costly reworks. We've had clients switch to our material and see a 90% reduction in dimensional defect rates.

Reliable ESD Protection:

As a professional Electrically Conductive PEI, it forms a continuous conductive network thanks to the uniform dispersion of conductive carbon fiber-unlike carbon black-modified PEI, which can have spotty conductivity. This ensures static charges are quickly channeled away from the IC TRAY to the ground, preventing static sparks that damage sensitive chips. In semiconductor manufacturing, where even a small static discharge can ruin a high-value IC, this reliability is non-negotiable.

Product Advantages

Having worked with IC TRAY manufacturers for years, we know what matters most: consistent quality, cost-effectiveness, and performance that solves real problems. Our Electrically Conductive PEI stands out from other conductive materials (conductive ABS, PC, or even ordinary carbon black PEI) for reasons that directly impact your bottom line:

■ Unbeatable Balance of Heat Resistance and Conductivity: Unlike conductive ABS or PC (which max out at 100°C), our thermally conductive PEI maintains stable conductivity and dimensional stability at 200°C-perfect for reflow soldering-compatible IC TRAYs and advanced packaging applications. Our thermally conductive PEI polymers also outperform ordinary carbon black PEI in flowability and conductivity consistency: carbon fiber's high aspect ratio creates a more uniform conductive network, eliminating "dead spots" that cause static buildup. This is a huge advantage for high-precision IC TRAYs where every square millimeter matters.

■ Cost-Effective High-Yield Production: The high flowability and consistent quality of our conducting plastics PEI cut scrap rates to below 2% (compared to 5–8% for ordinary conductive materials). Plus, our mature conductive carbon fiber modification process is more cost-efficient than graphene or carbon nanotube-based PEI, so you get superior performance without the premium price tag. We've seen clients reduce their overall production costs by 10–15% just by switching to our material-thanks to fewer defects, faster cycle times, and less material waste.

■ Batch-to-Batch Consistency You Can Trust: In the semiconductor industry, consistency is everything-even small variations in material properties can lead to failed IC TRAYs and rejected orders. We strictly control conductive carbon fiber content (15–25% adjustable) and dispersion during production, ensuring every batch of Conducting PEI has the same resistivity, flowability, and physical properties. No more surprises or rework due to inconsistent material-this is why top packaging and testing factories rely on our material for their high-volume orders.

■ Excellent Chemical and Environmental Resistance: Our Electrically Conductive PEI is resistant to the industrial chemicals commonly used in semiconductor manufacturing-alcohols, esters, weak acids, and cleaning agents-so your IC TRAYs won't degrade or deform. It's also RoHS and REACH compliant, free of heavy metals and harmful additives, making it suitable for global markets and eco-sensitive applications like medical electronics. Unlike some conductive materials that leach harmful substances, our material is safe for use with high-value IC chips.

■ Tailored Solutions for Your Exact Needs: We get it-no two IC TRAYs are the same. Different chips (QFP, BGA, LGA) and applications require different material properties. We can adjust the resistivity (conductive or static dissipative), flowability, and even hardness of our conducting plastics PEI to match your specific IC TRAY design, cavity structure, and production process. Whether you need a thin-wall, high-precision tray for 12-inch wafers or a durable tray for automotive ICs, we'll customize the material to fit-no extra cost, no long lead times.
