简介本文阐述了一种在聚酰亚胺树脂上,形成钯电路图形的简化方法。即通过树脂的羧化作用,使其吸附二价钯离子后,用 UV 光照射,有选择的还原钯离子而成。作为阳离子交换基的羧基,借助于氢氧化钾的处理,被引入到聚酰亚胺树脂的表面。UV(450瓦高压水银灯)光照射到用甲酸钠溶液涂复并吸附有二价钯离子的表面上,导致有选择的形成钯薄膜。获得的钯薄 INTRODUCTION This article describes a simplified method for forming a pattern of palladium circuits on a polyimide resin. That is, through the carboxylation of the resin to make it adsorb divalent palladium ions and then irradiate with UV light to selectively reduce palladium ions. The carboxyl group as a cation exchange group is introduced onto the surface of the polyimide resin by treatment with potassium hydroxide. UV (450 watt high pressure mercury lamp) light was irradiated onto the surface coated with sodium formate solution and adsorbed with divalent palladium ions, resulting in the selective formation of a palladium film. The palladium obtained was thin
