one、 Overview：

neutralWelding aidagentF-threethree0^#yes一種由抗氧化agent烷基咪唑、優質松香樹脂和neutral溶agent等配制而成of非活性松香Welding aidagent。適用于單面印刷電路板預涂和電子元件焊接，能長期保持潔凈銅箔具有良好of焊接性能、防止銅箔氧化。焊接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、六價鉻、鹵素化合物等對環境有害物質。毒性低，對操作員安全，對滾涂膠rollerof溶漲作用extremely低。

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.

在使用Time由于溶agent揮發會使Density andViscosity increases, recommendedD-three25^#稀釋agent稀釋。D-three25^#稀釋agentof使用量視環境溫度、濕度，所要求涂層of厚度、光ZeDegree and operating conditions. GenerallyF-threethree0^#ofone.5-2x.

D-three25^#稀釋agentyesF-threethree0^#of成份之一，密度為0.eight0—0.eightone。其成份為with異丙醇為主of低碳醇類。

4、 Packaging and storage：

packing:20 liters

Storage: store in a cool and ventilated place, away from the heat source. Class I inflammable product（three.one類）。

Period of validity: six months.

five、matters needing attention:

新配ofF-threethree0^#Welding aidagent顏色很淺，Welding aidagent覆蓋在board上呈透明狀。

Usually usedwith調節Stainless steel roller pressure、Welding aidagent濃度（用密度）來控制滾涂of厚度，使得膠轆上有一層均勻且厚度適合ofWelding aidagent轉移到板面上。

Stainless steel roller pressureSmall，膠轆上ofWelding aidagent就many，with可見到有一連續性of薄層均勻覆蓋為宜。

Welding aidagent密度高，膠轆上ofWelding aidagent就many，密度過高會使得Welding aidagent流動性變差（即粘度太大），影響Welding aidagentof均勻分布。

F-threethree0^#Welding aidagent工作液最佳of密度范圍yes0.nine0-0.nineone。

stainless steelroller, glueroller上粘有異物或磨損，會導致涂布不均勻，板面上部分無Welding aidagent或其厚薄不均，起不到保護板上銅面of作用。

因此日常工作必須包含檢查stainless steel轆, glue轆，調整其壓力with及用稀釋agentD-three25^#調節Welding aidagentof密度在合適of范圍內。

F-threethree0^#Welding aidagent與空氣接觸會緩慢氧化，作tradeTimeboard亦會帶入雜物（如沖壓產生of粉塵），因此在工作one00SmallTime后或顏色變為棕褐色TimeDiscard the old liquid and clean itManage storage containers后重新加入新ofF-threethree0^#Welding aidagent。
