Technology of electroless copper plating on alumina of aluminum substrate surface

The electroless copper plating coatings was practiced on alumina of Al substrate surface by molecular self-assembly active method. The coatings had excellent ablation strength and were characterized by SEM、EDS and ion chromatography. The relationship between silanization time and the modified quantity of APTS on substrate surface,the effect of Pd solution dip time on the quantity of Pd on the substrate surface and the effect of silanization time on the ablation strength of copper coating were studied. The best technological conditions obtained by the orthogonal test are as follows: the silanization time is 12 h,at 50 ℃ with w(3-aminopropyl) triethoxysilan (APTS) of 0.4%,Pd solution dip time and temperature of activation are 30 min and 30 ℃,respectively; gaining copper coating ablation strength is 1.00.
