凯斯特 免清洗助焊笔KESTER 951 KESTER 186松香笔 951免洗笔

951是一款无卤素、无松香有机助焊剂笔，专为传统和表面贴装电路板组件的返工而设计。极低的固体含量（2.0%）和活化剂系统的性质导致焊接后几乎没有残留在组件上。没有残留物干扰电气测试。

951具有改进的焊接性能，提高焊接速度与牢固度，以及在返工操作期间减少焊接桥（短路）。

这种焊剂适用于汽车、计算机、电信和其他可靠性考虑非常重要的应用。

钎焊板的表面绝缘电阻高于典型有机水溶性焊剂的表面绝缘电阻。

951含有一种缓蚀剂，当裸铜表面暴露在潮湿环境中时，不会形成腐蚀产物。

951笔头为圆形纤维笔头，当按下笔头时，助焊剂会随着笔头流向焊接板，助焊剂的多少与您按压笔头的力度，与移动笔头速度相关。可以根据您的焊点大小适当调节。

笔头直径约为：4.3mm

笔头露出长度约为:5-8mm

液体含量约：10ml

笔身长度（含笔帽）：14CM

笔身直径：15mm

单支重量：18g+/-1g

使用后请盖紧笔帽，以防止有效物质挥发。 

注意：此价格为单支价格，不是图中所示整盒或多支价格。

951 is a halogen-free, rosin free organic flux pen designed for rework of traditional and surface mount circuit board components. The very low solid content (2.0%) and the nature of the activator system result in little residue on the component after welding. No residue interferes with the electrical test.
951 has improved welding performance, increased welding speed and firmness, and minimized welding bridge (short circuit) during rework operation.
This flux is suitable for automotive, computer, telecommunications and other applications where reliability considerations are important.
The surface insulation resistance of brazed plate is higher than that of typical organic water-soluble flux.
951 contains an inhibitor that does not form corrosion products when exposed to moisture on bare copper surfaces.
951 pen head is a round fiber pen head. When pressing the pen head, the flux will flow to the welding plate along with the pen head. The amount of flux is related to the strength of pressing the pen head and the speed of moving the pen head. It can be adjusted according to the size of your solder joints.
The pen head diameter is about 4.3mm
The exposed length of the pen head is about 5-8mm
Liquid content: 10ml
Validity: 2 years
Please cover the cap tightly after use to prevent effective substances from volatilizing.
