剥锡铅液

PC-556
一﹑产品简介
I Product Introduction
PC-556是单液型的剥锡铅液,以硝酸为次要成份,十分良好的产品,能合适于以铜做为底材,电镀上锡铅金属或纯锡成品的镀层剥除用,实用范畴很广,如:印刷电路板﹑IC制造﹑产业产品等行业。
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﹑槽液剖析办法

V Analysis Method of Solution
1、比 重:比重计 1.2-1.4
1. Specific gravity: hydrometer 1.2-1.4
2、酸当量剖析
2. Analysis of acid equivalent
a、取5mL槽液参加100mL容量瓶中,加纯水浓缩至标线地位;
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浓缩液参加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,滴至溶液由白色变为黄色为尽头。
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

七﹑宁静防护
VII Safety Protection
PC-556为酸性液体,利用时请佩带眼罩、手套及穿宁静防护衣。若药液失慎溅及皮肤、眼睛时使用少量净水洗濯,严峻者应立刻就医诊治。
PC-556 is acid liquid, and when using it, please wear eyeshade, gloves and protective clothes; in case that solution spatters into eye or on skin, immediately flush with plenty of clean water and get medical treatment if necessary.
