one、 Overview

Micro etchantMicet Salt-threetwo6^#是一種專(zhuān)為印刷電路板電鍍前處理而配制的固體Micro etchant，其主要成分為酸性過(guò)硫酸鹽，它能迅速將銅箔腐蝕成一個(gè)均勻粗糙的表面。性能穩(wěn)定，易于清洗，對(duì)水質(zhì)無(wú)特別要求。

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

appearance: Colorless or white monoclinic crystal。

Density: ≈two.two

water content: ≤0twofive%

Decomposition temperature: ≥oneone0℃。

packing: two0公斤紙箱

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

新開(kāi)缸配料時(shí)，須加Initiator。否則開(kāi)始時(shí)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.
