Bingya An Integrated Solution to FPC Lamination Challenges

In FPC manufacturing, the lamination process is a key step that determines product yield. Traditional processes often require multiple layers of release film and cushioning materials stacked together, which is not only cumbersome but also prone to uneven pressure distribution and resin bleed contamination. Zhejiang Bingya Film Technology Co., Ltd. has introduced its three-in-one composite film — an innovative solution featuring an integrated "release + cushioning + substrate" structure.

The product uses a multi-layer gradient bonding design that integrates a release layer, substrate layer, and cushioning layer into a single film, delivering three functions at once: heat resistance, pressure equalization, and clean release. Compared with traditional multi-layer stacking, the three-in-one composite film significantly reduces production costs and labor time while ensuring uniform pressure distribution and contamination protection during lamination. It is suitable for PCB lamination and precision laminating processes.

In the field of TPX adhesive-coated release film, Bingya Technology also demonstrates strong technical capabilities. TPX (polymethylpentene) has a melting point of 230°C and can operate stably at temperatures up to 200°C. It offers over 90% light transmittance, excellent electrical insulation, and outstanding chemical resistance. Industry data shows that TPX high-temperature resin-barrier release film is mainly used in FPC lamination, semiconductor sealing, and AMC composite material manufacturing, capable of controlling solder pad resin bleed to below 2 mil while effectively preventing FPC transfer and static generation.

Bingya Technology's TPX adhesive-coated release film is specifically designed for FPC lamination. Through precise adhesive formulation control, it effectively manages resin bleed and static discharge, significantly improving lamination yield. Customized adhesive solutions can also meet the needs of advanced electronic packaging and composite material molding, providing customers with full-chain customization from concept to mass production.

The company operates an advanced coating production system equipped with precision testing instruments, ensuring strict quality control from formulation design to final delivery. With proprietary R&D, Bingya Technology has obtained multiple national patents and established long-term industry-university-research partnerships with several leading universities, continuously advancing material performance and expanding application boundaries.
