one、 Overview

neutralWelding aidagentF-threethree0#yes一種(zhong)由抗(kang)氧(yang)化agent烷基咪唑、優質松香樹脂和neutral溶agent等(deng)配制而成of非(fei)活性松香Welding aidagent。適(shi)用于單面(mian)印刷電路板預涂和(he)電子元件焊接(jie),能(neng)長期保持潔凈銅箔(bo)具有良好(hao)of焊接(jie)性能(neng)、防(fang)止銅箔(bo)氧化。焊接(jie)The solid is sublimated into gas phase after weldingthe residueextremelyLess, does not affect the electrical performance; Therefore, it is not necessary to clean after welding.

neutralWelding aidagentF-threethree0#不含如苯、鎘(ge)、六(liu)價鉻、鹵素化合物等對環境(jing)有害物質。毒(du)性低(di)(di),對操作員安全,對滾涂膠rollerof溶漲作用(yong)extremely低(di)(di)。

2、 Technical indicators

Appearance: light yellow viscous liquid

Density: 0.eighteight—0.nineone (25℃)

Viscosity: 2eight—three0CPS(25℃)

Solid content: thirty-five±one% (W/V)

Copper foil protection period: three months

Welding resistance: one0Sec(270℃)

three、 Method of use

Direct roll coating or brush coating. staywithWhen density is the reference index,0.eighteight—0.ninethreeA uniform and protective coating can usually be obtained by direct roll coating within the density range of.When the density is high, the gloss of the coating is good. Too high may make the coating too thick, waste and affect the electrical performance after welding.

在(zai)使(shi)用Time由(you)于溶agent揮發會使(shi)Density andViscosity increases, recommendedD-three25#稀釋agent稀釋。D-three25#稀釋(shi)agentof使用量視(shi)環境(jing)溫(wen)度、濕(shi)度,所要求涂層of厚(hou)度、光ZeDegree and operating conditions. GenerallyF-threethree0#ofone.5-2x.

D-three25#稀(xi)釋agentyesF-threethree0#of成份之一,密度為(wei)0.eight0—0.eightone。其(qi)成份為with異丙醇為主of低碳(tan)醇類(lei)。

4、 Packaging and storage

packing:20 liters

Storage: store in a cool and ventilated place, away from the heat source. Class I inflammable productthree.one類

Period of validity: six months.

fivematters needing attention:

新配ofF-threethree0#Welding aidagent顏色(se)很淺(qian),Welding aidagent覆蓋在board上呈透明狀。

Usually usedwith調(diao)節Stainless steel roller pressure、Welding aidagent濃度(用(yong)密度)來控制滾涂(tu)of厚度,使得(de)膠轆(lu)上(shang)(shang)有(you)一層均勻且厚度適合ofWelding aidagent轉移到板(ban)面上(shang)(shang)。

Stainless steel roller pressureSmall,膠轆上ofWelding aidagent就manywith可見到有一(yi)連續性of薄層均勻覆蓋為(wei)宜。

Welding aidagent密度高(gao),膠(jiao)轆上ofWelding aidagent就many,密度過高會使得(de)Welding aidagent流動性變(bian)差(即粘度太大),影(ying)響Welding aidagentof均(jun)勻分布。

F-threethree0#Welding aidagent工作液最佳of密度(du)范(fan)圍(wei)yes0.nine0-0.nineone

stainless steelroller, glueroller上粘有異物或磨損,會(hui)導(dao)致涂(tu)布不均勻,板面(mian)上部分無Welding aidagent或其厚薄不均,起不到保護板上銅面(mian)of作用。

因此日(ri)常工作(zuo)必須包含檢查stainless steel轆, glue轆,調整(zheng)其壓力with及用稀(xi)釋agentD-three25#調節Welding aidagentof密度(du)在合適of范圍內。

F-threethree0#Welding aidagent與(yu)空氣接觸(chu)會緩(huan)慢氧化(hua),作tradeTimeboard亦會帶入雜物(如沖(chong)壓產(chan)生of粉塵),因此在(zai)工作one00SmallTime后或顏色(se)變為棕褐色(se)TimeDiscard the old liquid and clean itManage storage containers后(hou)重新(xin)加入新(xin)ofF-threethree0#Welding aidagent。
