Brief introduction of single liquid acid etching solution sec--160#

2022-03-02 347

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刻鹽。其中氨water+Erode刻鹽及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).

但是,在實際作業(yè)時,并不需要按上述方法配槽,而是使用現(xiàn)有的acid性Copper chlorideErode刻廢液( 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.通常將該等Erode刻廢液稱為母液,各種acid性Copper chloride的Erode刻廢液( ashydrochloric acid-hydrogen peroxide solution、hydrochloric acid-氯acid鹽或hydrochloric acid-催化劑型的Erode刻廢液)均可作為SEC-onesixty#Acid etching solution的母液。

4、 Maintenance:

becauseSEC-onesixty#Acid etching solution中hydrochloric acidstrongdegree較低,yes雜質(zhì)的溶解力不ashydrochloric acid-hydrogen peroxide solution型Erode刻液強,應(yīng)盡amount避免Erode刻液受污染。需每天清洗過濾網(wǎng),同時留意噴嘴是否堵塞,Erode刻機one5-30天清洗一次。

5、 Safety, storage and transportation:

本品具有腐Erode性,操作時需穿保護衣物及戴上手套。as不慎接觸皮膚及眼睛,必須用大amount清water沖洗,嚴重時要送醫(yī)院治療。

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

6、 Troubleshooting:

SEC-onesixty#Acid etching solution相當穩(wěn)定,在正常情況下僅需控制工作液的密degree即可使Erode刻快速、穩(wěn)定的進行。在控制不良時,其故障及排除方法as下:

one、Erode刻速degree變慢

通常是由于temperaturedegree或噴淋壓力過低造become。在上述條件正常情況下,則有可能是銅含amount過高或過低。根據(jù)具體情況采用 one)補充SEC-onesixty#降低密degree至two4oBe。two)添加高strongdegree的母液或Erode刻廢板至銅含amount正常。

two、Precipitation of working fluid

可能是銅含amount過高或hydrochloric acid含amount不足。銅含amount過高時還伴隨Erode刻速degree變慢、溶液粘degree增加等現(xiàn)象,按前款之one)處理。hydrochloric acid含amount不足可根據(jù)化驗結(jié)果補充hydrochloric acid。

3、Irregular brown patches appear on the board

這是hydrochloric acid含amount不足所致。用稀hydrochloric acid溶液清洗,可發(fā)現(xiàn)斑塊下是未被Erode刻掉的銅。產(chǎn)生這種現(xiàn)象,Erode刻液中hydrochloric acid含amount僅有3-5%, to be supplemented to 7-8%.

4、抗Erode劑被破壞

hydrochloric acid含amount及temperaturedegree過高,造become線路Erode刻不整齊( 鋸齒狀)。

板子在用water洗時,殘留在板上的工作液出現(xiàn)白色混濁( 可被water洗去)屬正常現(xiàn)象。

七、cost accounting:

密degree: two4-two6oBe

Spray pressure: two.two-two.5Kg/cmtwo

Erode刻速degree: twoM/Min

銅箔厚degree: H/0

Under the above conditions, per tonSEC-onesixty#Acid etching solution( 以含稅價onetwo00/噸計)可Erode銅板約onetwo00Mtwo,產(chǎn)生Erode銅廢液onetwo00Kg( 以不含稅價900/噸計),其材料become本as下式:
