资料介绍

开发出了一种双面印制电路板的加成法制备工艺,其具体流程包括:(1)在基板上需要双面导通的部位钻孔,并浸涂离子吸附功能油墨;(2)在基板双面印刷掩膜,暴露出线路图形与通孔部位;(3)基板浸入硝酸银溶液中,吸附银离子至图形和通孔表面;(4)除去掩膜,使用化学镀铜的方法使表面线路和通孔金属化,得到所需双面印制电路板。本工艺可以将双面印制电路线路和通孔一步加成制造,简化了工序,降低了成本,节约了材料。

A Patterning-Adsorption-Plating (PAP) process to additively fabricate double-sided printed circuit board (PCB) is developed. The main steps of PAP additive process include: (1) drilling hole in the substrate where needed, then immerging the substrate into the ion-adsorption ink, (2) printing mask on the substrate with patterns and through holes exposed, (3) immerging the substrate into the solution of silver nitrate, thus the silver ion can be adsorbed onto the patterns and through holes, (4) removing mask, then metalizing patterns and through hole by electroless plating of copper. Double-side PCB can be one-step fabricated by PAP additive process with simple procedure, low pollution and low waste is realized.
