[Release Location: Shenzhen/Pingshan] – Recently, a leading provider of precision electronic materials officially announced the launch of the next-generation DSPI Series High-Flexibility Polyimide (PI) Coverlay. Leveraging advanced coating technology and superior lamination stability, this series is specifically engineered for surface insulation and protection of high-precision Flexible Printed Circuits (FPCs), marking another significant technological milestone for the company in high-end substrate materials.
The DSPI series utilizes an industry-standard three-layer composite structure to ensure flawless performance from production to end-use:
PI Film Layer: Provides exceptional thermal resistance and electrical insulation.
Adhesive Layer: Delivers powerful bonding to ensure no delamination or bubbling even in complex, high-flex environments.
Protective Film Layer: Features stable release properties, effectively preventing scratches and contamination during the manufacturing process.
To meet the rigorous demands for thickness and durability across various terminal devices, the DSPI series offers a comprehensive range of total thicknesses from 28μm to 80μm:
| Model | PI Film | Adhesive | Protective Film | Total Thickness |
| DSPI1315 | 13μm | 15μm | 25μm | 28μm |
| DSPI2525 | 25μm | 25μm | 25μm | 50μm |
| DSPI5020 | 50μm | 20μm | 25μm | 70μm |
| DSPI5025 | 50μm | 25μm | 25μm | 75μm |
| DSPI5030 | 50μm | 30μm | 25μm | 80μm |
Beyond standard specifications, the DSPI series demonstrates high flexibility to adapt to the rapid iterations of the FPC industry:
Width Customization: Supports standard widths of 250/500mm as well as specialized custom widths.
Adjustable Adhesive Thickness: Adhesive layers can be customized based on specific customer requirements for gap filling and overflow control.
Variable Lengths: Single-roll lengths are available in 100m, 200m, or bespoke lengths to reduce changeover frequency and boost production line efficiency.
The DSPI series is widely utilized in smartphones, tablets, automotive displays, medical devices, and precision sensors. With its excellent solder resistance and chemical stability, it achieves industry-leading performance in repetitive bending tests, making it the ideal choice for precision flexible interconnect solutions.
"With the arrival of the 5G and foldable screen era, the market's reliability requirements for coverlays are higher than ever," stated the company's Technical Director. "By optimizing our adhesive formulation, the DSPI series successfully balances 'ultra-thinness' with 'high protection,' driving the upgrade of domestic FPC materials."
