摘 要文本采用3,3',4,4'-二苯醚四甲酸二酐(ODPA)、葵二胺(DDA)、二氨基二苯醚(ODA)为原料,通过二步法制备聚酰亚胺(PI)薄膜,利用热层压法将PI薄膜和铜箔压合得到两层柔性覆铜板(FCCL)。通过再次热处理的方法得到高尺寸稳定性的柔性覆铜板。采用红外光谱(FTIR)、热失重分析(TG)、差式扫描量热仪(DSC)、静态热机械分析(TMA)、扫描电子显微镜(SEM)、X射线衍射(XRD)以及万能电子拉伸机等测试手段,对聚酰亚胺的性能及所得覆铜板的性能进行了研究。31367
结果表明:PI薄膜的拉伸强度随着DDA用量的增加而降低,但所得FCCL的剥离强度显著提高。当DDA:ODA为20: 80(摩尔比)时,聚酰亚胺薄膜的拉伸强度为90MPa,其热分解温度为413.93℃,在516.3℃达到最大分解速率。利用厚度为40μm的电解铜箔与该组分PI薄膜制备FCCL,其剥离强度可达1.4N/mm,综合性能较好。此外,通过高温热处理得到的FCCL尺寸稳定性最佳,能通过360℃耐焊锡浴测试。

Title Preparation and properties for polyimide materials used in two-layer FCCL with high dimensional stability
Abstract
In this article, we use diaanhydride like 4,4'-oxydiphthalic Anhydride (ODPA), diamine like4,4'-Diaminodiphenyl Ether(ODA)and 1,10-Diaminodecane (DDA) as raw materials to produce polyimide film through two-step processing. Using thermal laminating to laminate copper with PI film to manufacture flexible copper clad laminate (FCCL), we obtained highly dimensional stabile FCCL by second thermal treatment. We take infrared spectroscopy (FTIR), thermal gravimetric analysis (TG), universal electronic tensile machine, scanning electronic microscope (SEM), X-ray diffraction (XRD) and adhesion test to analyze the properties of PI film and FCCL.
The result shows: the tensile strength of PI reduced with the increase of DDA content, meanwhile the peel strength enhanced. When the ratio of DDA and ODA equals 20 to 80, the FCCL has the highest peel strength, and thermal stability of PI met the requirement, the thermal decomposition temperature reaches to 413.93 ℃, the maximum decomposition rate is 516.3℃. Laminating 40μm thick copper foil with this PI film can get the highest peel strength 1.4N/mm, comprehensive ability performs well. In addition, after the second thermal treatment, FCCL shows great dimensional stability by passing the 360℃ Tin solder bath.
Keywords : polyimide; FCCL; dimensional stability; coefficient of thermal expansion
