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 solution—SEC-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.

自動：將Compare重(zhong)控(kong)制調節在(zai)two5-two7oBe之間，較低的Compare重可得到較快的Erode刻速degree。調節方法參照設備說明書。

When preparing the tank, add the following components into the water in sequence, and the solid materials must be completely dissolved:

但是(shi)，在實際作業(ye)時，并不(bu)(bu)需要按上述(shu)方法配槽(cao)，而是(shi)使用現(xian)有的(de)acid性(xing)Copper chlorideErode刻廢液(ye)（ baume degrees不(bu)(bu)小于two5degree）添加SEC-onesixty^#，配become的(de)工作(zuo)液twotwo-two4baume degrees、SEC-onesixty^#添(tian)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(zhong)hydrochloric acidstrongdegree較低，yes雜質的溶解力不ashydrochloric acid-hydrogen peroxide solution型Erode刻液強，應盡amount避免Erode刻液受污染。需每天清洗過濾網，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(pin)具有(you)腐Erode性(xing)，操作時需穿保護衣物(wu)及(ji)戴上(shang)手套。as不(bu)慎接觸皮膚及(ji)眼(yan)睛，必(bi)須用大(da)amount清(qing)water沖洗，嚴重(zhong)時要送(song)醫(yi)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相當穩定(ding)，在正常情況(kuang)下僅(jin)需控制工作液的密degree即(ji)可(ke)使Erode刻快速、穩定(ding)的進行(xing)。在控制不良時(shi)，其故障及排(pai)除方(fang)法as下：

one、Erode刻速degree變(bian)慢

通常是由于(yu)temperaturedegree或(huo)(huo)噴淋(lin)壓力過低造become。在上述條件正常情況(kuang)下，則有可能是銅含amount過高或(huo)(huo)過低。根據具體情況(kuang)采用 one）補充SEC-onesixty^#降低密degree至(zhi)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(tong)含(han)amount過高或hydrochloric acid含(han)amount不(bu)足。銅(tong)含(han)amount過高時還伴隨Erode刻速degree變慢、溶(rong)液粘degree增加等(deng)現象，按前(qian)款之(zhi)one）處理。hydrochloric acid含amount不足可根據化驗結果補充hydrochloric acid。

3、Irregular brown patches appear on the board

這是(shi)hydrochloric acid含amount不足(zu)所致。用稀hydrochloric acid溶(rong)液(ye)清(qing)洗(xi)，可(ke)發現斑塊下(xia)是(shi)未(wei)被Erode刻掉(diao)的(de)銅(tong)。產生這種現象，Erode刻液(ye)中hydrochloric acid含amount僅(jin)有3-5%, to be supplemented to 7-8%.

4、抗Erode劑被破(po)壞

hydrochloric acid含amount及(ji)temperaturedegree過(guo)高，造(zao)become線路Erode刻(ke)不整齊（ 鋸齒(chi)狀）。

板子在用water洗時，殘(can)留在板上的工作液出現白色混(hun)濁（ 可被water洗去）屬正常現象(xiang)。
