one、 Overview

Micro etchantMicet Salt-threetwo6^#是(shi)一種專為印刷電路板(ban)電鍍前(qian)處理而配制(zhi)的(de)固體Micro etchant，其主要(yao)成分為酸性過硫酸鹽，它能迅速將銅(tong)箔腐蝕成一個(ge)均(jun)勻粗糙的(de)表面。性能穩定(ding)，易于清(qing)洗，對水(shui)質無特別要(yao)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

appearance: Colorless or white monoclinic crystal。

Density: ≈two.two

water content: ≤0twofive%

three、 Processing program

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

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(xin)開(kai)缸配料時(shi)，須(xu)加(jia)Initiator。否則開(kai)始時(shi)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.
