I Product Introduction

΢ʴҺME-90SΪ˫ˮϵ֮΢ʴȶ΢ʴʣ˫ˮӷ΢ʴЧЧֻͭ棬Ϊ޻ͭЧƳ⡣
Micro0etching liquid ME-90S belongs to series of sulfuric acid and hydrogen peroxide, and has stable micro-etching velocity; control the volatilization of hydrogen peroxide, and the micro-etching can effectively and averagely roughen copper surface; as it is inorganic matter, it is not easy to cause oxidation of copper surface, and can effectively clean board, so to avoid problems in later process.

IV Analysis Method

ͭ 1ȡҺ1ml Ӵˮ100 ml;
Copper content: Method: 1. Take 1ml solution and add with 100ml pure water;
2buffer solution(9.5)10ml2-3PANָʾ;
2. Add buffer solution (9.5)10ml, and add 2-3 drops of PAN indicator;
30.1N EDTAζɫΪյ.
3. Use 0.1N EDTA for titration till ghe color is grass green;
㣺Cu(g/L)=V6.354
Calculation: Cu(g/L)=V6.354
ͭ50g/Lʱ뵱ۣŵĸҺӦME-90S
When copper content reaches 50g/L, stop or drain part mother liquid, and add relevant ME-90S;
˫ˮ 1ȡ1MLҺ250ML׶ƿ;
Hydrogen peroxide: Method: 1. Measure 1ML solution and place into 250ml conical flask;
2100MLDIˮ20ML 20%;
2. Add 100ml DI water, and add 20ml 20% sulfuric acid;
