one、 Overview

Micro etchantMicet Salt-threetwo6^#是一种专为印刷电路板电镀前处理而配制的固体Micro etchant，其主要成分为酸性过硫酸盐，它能迅速将铜箔腐蚀成一个均匀粗糙的表面。性能稳定，易于清洗，对水质无特别要求。

Micro etchantMicet Salt-threetwo6^#It can also be used in other processes requiring micro etching of copper foil.

Micro etchantMicet Salt-threetwo6^#It is applicable to spraying operation mode and soaking operation mode.

two、 Technical indicators

Density: ≈two.two

water content: ≤0twofive%

Decomposition temperature: ≥oneone0℃。

packing: two0公斤纸箱

three、 Processing program

Degreasing—→水洗—→MS-threetwo6^#Micro erosion（twofive℃ three-fivemin）—→水洗—→酸洗—→镀铜或其它工序

4、 Operating conditions

MS-threetwo6^#onetwo.five—onefive% （W/V）

Initiator five—one0g/L

temperature two0—threefive℃

time two—fivemin (soaking operation, air mixing)

one—fivemin(spraying operation)

cooling As needed

five、 Solution control

新开缸配料时，须加Initiator。否则开始时微The erosion rate is slow.

When the micro etching speed starts to slow down significantly or the copper ion content reachesthreefiveg/L, replace the old working fluid and prepare a new one.

When the liquid medicine is replaced, it can be retained for aboutone0%Old working fluid fromTrigger action. At this time, the micro etching speed can be fast and stable.

6、 Storage

Storage: This productIt is a strong oxidant. It should be stored in a cool, dry and ventilated place and sealed separately. Note: do not store it with organic substances, otherwise it may burn or even explode!

Period of validity: six months.
