1、附部分蚀刻液配方：  （一） 化学腐蚀    主要用强酸、混合酸、酸+盐或碱+盐的混合物。               黄铜蚀刻液配方：          1  三氯化铁（25-45）°Be      80-85 %           浓盐酸                                   15-20% 蚀刻温度：30-40度 缺点：腐蚀液无法再生，有污染。用于铝箔           蚀刻时，铝箔上常有少量黄色残留物，难以清洗。       2  氯化铜                         

2、           5 %            浓盐酸                                    10%            双氧水                                    25%            水                                        60% 蚀刻温度30-40度优点：用双氧水使氯化亚铜氧化再生并可回收                                                         

3、                3   氯化铜                                     15   %            氨水                                       10-20%            蚀刻温度：                                 40-60度            PH                                        9.5-9.8            4   浓盐酸     

4、                                20-50%            水                                            20-80%            蚀刻温度：                            40-50度       5   磷酸                                         80-85%            蚀刻温度：                           40-60度    

5、   6   氢氧化钠                                  10-20%            水                                             80-90 %            不锈钢蚀刻液配方：        7    浓盐酸                                    210克/升            浓硝酸                                    200克/升            冰醋

6、酸                                    20克/升                氢氟酸                                    200克/升  磷酸氢二钠                           12个结晶水   12克/升            水                                            358克/升            蚀刻温度：                            30-50度 

7、      8   浓盐酸       586毫升/升            浓硝酸       80.5毫升/升            氯化镍       9.6克/升            三氯化铁    344.5克/升            水           加水到一升。 蚀刻温度：24-60度                                9  三氯化铁（45-48）°Be    65%            蚀刻温度：30-50度       10  三氯化铁（30-42）°Be     67

8、%            双氧水                                16%
