951是一款無鹵素、無松香有機助焊劑筆，專為傳統和表面貼裝電路板組件的返工而設計。極低的固體含量（2.0%）和活化劑系統的性質導致焊接后幾乎沒有殘留在組件上。沒有殘留物干擾電氣測試。

951具有改進的焊接性能，提高焊接速度與牢固度，以及在返工操作期間減少焊接橋（短路）。

這種焊劑適用于汽車、計算機、電信和其他可靠性考慮非常重要的應用。

釬焊板的表面絕緣電阻高于典型有機水溶性焊劑的表面絕緣電阻。

951含有一種緩蝕劑，當裸銅表面暴露在潮濕環境中時，不會形成腐蝕產物。

951筆頭為圓形纖維筆頭，當按下筆頭時，助焊劑會隨著筆頭流向焊接板，助焊劑的多少與您按壓筆頭的力度，與移動筆頭速度相關。可以根據您的焊點大小適當調節。

筆頭直徑約為：4.3mm

筆頭露出長度約為:5-8mm

液體含量約：10ml

筆身長度（含筆帽）：14CM

筆身直徑：15mm

單支重量：18g+/-1g

使用后請蓋緊筆帽，以防止有效物質揮發。 

注意：此價格為單支價格，不是圖中所示整盒或多支價格。

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.
Note: this price is a single price, not a whole box or multiple prices as shown in the figure.
