一﹑产品简介
I Product Introduction
PC-556是单液型的剥锡铅液,以硝酸为主要成份,非常优秀的产品,能适合于以铜做为底材,电镀上锡铅金属或纯锡制品的镀层剥除用,适用范围很广,如:印刷电路板﹑IC制造﹑工业产品等行业。
PC-556 is a single-liquid tin-lead stripping solution with nitric acid as the main content and is a very good product; it can be applied for stripping the tin-lead or pure tin plating with copper as the base-material and has wide application scope, e.g., print circuit board, IC manufacture and industrial product.

四﹑槽液控制
IV Control of Solution
1、比重控制1.2-1.4(1.3-1.35最佳)
1. Specific gravity controlled as 1.2-1.4 (1.3-1.35 is better);
2、酸当量控制3.5N以上
2. Acid equivalent controlled as above 3.5N;
五﹑槽液分析方法
V Analysis Method of Solution
1、比 重:比重计 1.2-1.4
1. Specific gravity: hydrometer 1.2-1.4
2、酸当量分析
2. Analysis of acid equivalent
a、取5mL槽液加入100mL容量瓶中,加纯水稀释至标线位置;
a. Take 5ml solution and add it into a 100ml flask, and add pure water to dilute the solution to the designated level;
b、取5mL稀释液加入250mL锥形瓶中,再加纯水100mL;
b. Take 5ml diluted solution and add it into a 250ml conical flask, and then add 100ml pure water;
c、加3-5滴甲基红指示剂;
c. Add 3-5 drops of methyl red indicator;
d、用0.1N NaoH滴定,滴至溶液由红色变为黄色为终点。
d. Uuse 0.1N NaoH for titration till the solution turns from red to yellow;
计 算:酸当量(N)=0.1 × V0.1N NaoH(ml)× 4
Calculation: acid equivalent (N) = 0.1 × V0.1N NaoH(ml)× 4
