In Flexible Printed Circuit (FPC) multi-layer lamination and Coverlay bonding, ensuring uniform pressure and heat distribution across hundreds of micro-nodes is the key to yield. The Silicone Iron Plates serves as the central component of the lamination fixture, directly influencing thermal transfer efficiency and the quality of post-process release.
Material Science: Thermal Gradients and Stress Distribution Models The superior performance of Lixing Silicone Iron Plates stems from highly stable alloy properties and advanced surface treatments:
-
Steady-state Conduction and Fourier’s Law: During lamination, the plate must transfer heat rapidly and uniformly. This behavior follows Fourier’s Law: q = k * (dT / dx) (Pure text: q = k * (dT / dx), where q is heat flux, k is thermal conductivity, and dT/dx is the temperature gradient) Lixing utilizes alloy steels with high thermal diffusivity, minimizing surface temperature variance to prevent localized base-material carbonization.
-
High Flatness and Stress Uniformity: Even micro-scale flatness errors can cause uneven resin flow or circuit shifting. P = F / A (Pure text: P = F / A, Pressure equals total force divided by effective contact area)
-
Interface Chemistry and Release Properties: Lixing Silicone Iron Plates feature a composite surface coating with extremely low surface energy. This effectively controls resin flow and ensures effortless release after cooling, extending tool life significantly.
