Silicone Aluminum Foil Pad for FPC Hot Press

Silicone Aluminum Foil Pad

Overview: This silicone aluminum foil cushion pad combines the rigidity of aluminum foil with the excellent elasticity of silicone, delivering outstanding flatness and uniform heat transfer for the FPC hot-press process. With a long service life of more than 6,000 cycles, it effectively prevents localized heat concentration during pressing, making it a key consumable for improving lamination precision and protecting delicate circuits.

In brief: The aluminum foil layer keeps the pad flat under press pressure while the silicone layer evens out heat and contact, so every FPC lamination cycle sees consistent pressure and temperature. Rated for more than 6,000 cycles, it lowers consumable replacement frequency and protects fine circuitry from hot spots.

Silicone Aluminum Foil Pad: Premium Solution for Thermal Buffering & Structural Integrity

In the hot press lamination processes of FPC (Flexible Printed Circuits) and battery conductive lines, the Silicone Aluminum Foil Pad is a core material for achieving precise pressure distribution and high-efficiency gap filling. The Silicone Aluminum Foil Pad provided by Lixing Composite Materials features a precision composite of high-performance silicone and aluminum foil, delivering exceptional thermal buffering and flatness. It effectively strengthens product bonding and significantly extends the service life of production equipment.

[Why Choose Our Silicone Aluminum Foil Pad?]

Structural Stability: The aluminum foil substrate provides rigid support, maintaining excellent flatness even under high pressures of 80 to 150 kgf/cm², preventing deformation.
Superior Filling & Molding: The high-quality silicone layer offers excellent gap-filling properties, ensuring better product molding and stronger interlaminar bonding during the thermal press cycle.
Uniform Heat Transfer: Installed on the hot plate, it ensures a more even temperature distribution, improving yield rates while providing thermal protection for operators.
Extreme Heat Resistance: Rated for temperatures over 280°C, with a recommended operating range of 160°C to 250°C for long-term stability.
Extended Service Life: Highly durable with a typical service life of 6,000 to 8,000 cycles under normal operation, significantly reducing replacement costs.

[Functions & Notice]

Quality Control: It is recommended to cover the silicone surface with fiberglass cloth during operation to effectively prevent silicone oil migration from affecting product quality.
Installation Requirements: The hot plate surface must be flat and free of scratches. Ensure the pad is installed as flatly as possible against the heating surface to avoid air gaps.
Longevity Tip: Lowering operating temperatures and pressures where process conditions allow will further extend the product’s lifespan.
