Meanwhile, the dibenzothiophene structure contained in the polyimide substructure has high planarity and stronger rigidity, so that the composite polyimide copper plate has excellent thermal stability and low thermal expansion. Lingaiah et al. Two different methods of surface treatment, a low pressure plasma treatment and an atmospheric plasma treatment, on polyamide (PI) substrate were investigated from the point of view of adhesion of a Cu/80Ni20Cr layer on PI in flexible copper clad laminate (FCCL). Product type: PI FCCL. Conclusion. ThinFlex Corporation No. Dielectric properties of cured PI resins and QF/PI composite The dielectric constants and dissipation factors of the cured PI resins and QF/PI-4 at high frequency ranging from 1 GHz to 12 GHz were investigated on a vector network analyzer (Agilent E8363B), and the. 0mil Thickness of Cu 05：0. The TPCPOHPPI-based two-layer black flexible copper clad laminate (2L-FCCL) possessed good dip soldering resistance and peeling strength. In contrast to adhesive-based flex cores, adhesiveless flex cores don’t use an adhesive. Before C film deposition, the PI sample surfaces are treated with a pure Ar plasma at a pressure of 67 Pa and the fixed microwave power of 1. All-Polyimide Flexible Laminate A Family of High-Performance Adhesiveless Laminates for Flexible Printed Circuit Applications Technical Information Table 1 Pyralux® AP Product Offerings* Dielectric Thickness, Copper Thickness, Product Code 2mil µm (oz/ft ) AP 7163E** 1. Instead, manufacturers cast the polyimide core onto the copper, removing the need for an adhesive bond. As the raw material of FPCBs, adhesiveless flexible copper clad laminates (FCCLs) with polyimide (PI) film substrate are characterized by high dimensional stability and heat resistance, so that they are highly desired for high-end application scenarios (e.
