Ibrief introduction

SEC-onesixty#It is a new type of single liquid acid etching solution, which has the characteristics of simple control, low hydrochloric acid content, fast etching rate and high copper dissolution. The drug solution has excellent stability and small side corrosion. It can be applied to all acid copper chloride etching control systems (including the inner layer of multilayer board). Mainly used for:

one. Replace hydrogen peroxide or chlorate to avoid danger.

two Replace ferric chloride to avoid environmental pollution.

3. Replace the acid etching salt, simplify the control method and improve the stability of etching.

4. Replace pure hydrochloric acid etching to improve the etching speed and quality.

In the current circuit board industry, the traditional etching method is ferric chloride etching,Hydrochloric acid etching,hydrochloric acid+Regenerant (hydrogen peroxide, etching salt, chlorate solution), ammonia+Erode刻盐。其中氨water+Erode刻盐及hydrochloric acid+It can be used in any ordinary way, so it can be used in any board regeneration system.

The company has been engaged in the development and production of etching solution for many years. O n the basis of absorbing the experience of peers and repeated tests, the company has developed a new generation of etching solutionSEC-onesixty#。 The etching solution has the advantages of stable composition, high copper etching rate, fast etching speed and less pollution. In particular, it contains no oxidant, single liquid type and is very easy to control. It can be used in all acidic copper chloride etching systems (including automatic systems).

3、 Usage and solution control:

It can be added automatically or manually.

Manual: release it firstone/5-one/4母液,然后加入同等amount的补充液。

自动:将Compare重控制调节在two5-two7ºBe之间,较低的Compare重可得到较快的Erode刻速degree。调节方法参照设备说明书。

但是,在实际作业时,并不需要按上述方法配槽,而是使用现有的acid性Copper chlorideErode刻废液( baume degrees不小于two5degree)添加SEC-onesixty#,配become的工作液twotwo-two4baume degrees、SEC-onesixty#添加amount不少于two0%Just.通常将该等Erode刻废液称为母液,各种acid性Copper chloride的Erode刻废液( ashydrochloric acid-hydrogen peroxide solution、hydrochloric acid-氯acid盐或hydrochloric acid-催化剂型的Erode刻废液)均可作为SEC-onesixty#Acid etching solution的母液。

4、 Maintenance:

becauseSEC-onesixty#Acid etching solution中hydrochloric acidstrongdegree较低,yes杂质的溶解力不ashydrochloric acid-hydrogen peroxide solution型Erode刻液强,应尽amount避免Erode刻液受污染。需每天清洗过滤网,同时留意喷嘴是否堵塞,Erode刻机one5-30天清洗一次。

5、 Safety, storage and transportation:

本品具有腐Erode性,操作时需穿保护衣物及戴上手套。as不慎接触皮肤及眼睛,必须用大amount清water冲洗,严重时要送医院治疗。

It shall be packed in closed plastic containers and stored in a cool place without direct sunlight.

6、 Troubleshooting:

SEC-onesixty#Acid etching solution相当稳定,在正常情况下仅需控制工作液的密degree即可使Erode刻快速、稳定的进行。在控制不良时,其故障及排除方法as下:

one、Erode刻速degree变慢

通常是由于temperaturedegree或喷淋压力过低造become。在上述条件正常情况下,则有可能是铜含amount过高或过低。根据具体情况采用 one)补充SEC-onesixty#降低密degree至two4ºBe。two)添加高strongdegree的母液或Erode刻废板至铜含amount正常。

two、Precipitation of working fluid

可能是铜含amount过高或hydrochloric acid含amount不足。铜含amount过高时还伴随Erode刻速degree变慢、溶液粘degree增加等现象,按前款之one)处理。hydrochloric acid含amount不足可根据化验结果补充hydrochloric acid。

3、Irregular brown patches appear on the board

这是hydrochloric acid含amount不足所致。用稀hydrochloric acid溶液清洗,可发现斑块下是未被Erode刻掉的铜。产生这种现象,Erode刻液中hydrochloric acid含amount仅有3-5%, to be supplemented to 7-8%.

4、抗Erode剂被破坏

hydrochloric acid含amount及temperaturedegree过高,造become线路Erode刻不整齐( 锯齿状)。

板子在用water洗时,残留在板上的工作液出现白色混浊( 可被water洗去)属正常现象。
