摘要
研究了膨润液中N-甲基吡咯烷酮含量、膨润温度、膨润时间对微蚀效果的影响,以微蚀后聚碳酸酯基板的表面形貌、水接触角及基板之间与镀铜层间的粘结强度对微蚀效果进行评定。结果表明,当聚碳酸酯基板先用70%N-甲基吡咯烷酮-15%乙二醇乙醚-15%水溶液在40℃膨润处理7 min后,再经80 g/L MnO2,V(H3PO4)∶V(H2O)∶V(H2SO4)=1∶1∶3.5的胶体溶液70℃处理10min,可得到较理想的微蚀效果,其表面接触角可低至25.2°,基板与镀铜层的粘结强度可达0.93kN/m。
MnO2-H3PO4-H2O-H2SO4 system was used to etch the surface of polycarbonate plastic （PC）.The effects of NMP （N-methylpyrrolidone） concentration,swelling temperature and swelling time on the etching performance were studied by surface morphology,surface contact angle measurement,and adhesion strength measurement.PC substrates were swelled in a solution of 70 vol% NMP and 15% ethylene glycol diethyl ether at 40 ℃ for 7 min,and thereafter etched in a colloid containing MnO2 80g/L,V（H3PO4） ∶ V（H2O） ∶ V（H2SO4） =1∶1 ∶ 3.5 at 70 ℃ for 10 min.The surface contact angle of the PC substrate reached 25.2°,and the adhesion strength between electroless copper and the PC substrate reached 0.93 kN/m.
