焊点保护UV胶是一种什么特性的胶水？该如何选用？

焊点保护UV胶是一款单组份紫外光固化胶，在紫外光的照射下，能迅速硬化并产生强韧的接著特性，产品具有优异的柔韧性，气味低、表干性好、固化速度快、粘接强度高。并且胶液粘度高还具有一定的触变性对施工有很大帮助，典型用于电子元器件、电感、电容器、电路板、排线、数据线、连接器等产品的粘接、密封、绝缘、固定以及焊点的固锡保护，UV胶水固化时间短，能提高生产效率，增强上锡点的抗拉强度，适合自动化生产线作业

焊点保护UV胶的特点是耐冲击，耐震，抗湿，固化快速，较好的表干和深层固化能力；低气味，几乎无刺激不易致敏；流动性佳，不拉丝不垂流，良好的挤出性；柔韧性佳，对金属塑胶均有一定附力。

一、产品说明：H600-N 是一种单组份半流淌紫外线固化胶，适用于多种材料粘接，推荐用于电子电路元器件粘接固定、电子线路焊点保护、线路焊点线材补强粘接及电子元器件绝缘保护，密封等；常温储存稳定，固化速度快，表层固化完全光亮不粘，固化胶膜柔韧，抗冲击性强，抗湿热及化学品优良，优越的电气特性，绝缘防水防潮防尘等。

二、化学物质类型      改性丙烯酸酯        

外观                          淡黄色透明半流体

粘度(mPa.s/25℃)    15000-25000         

密度25℃ g/cm³       1.1

三、固化性能：H600-N在空气环境下需要足够的紫外能量辐射才能够固化。固化速率和固化效果需要足够的光能量，主要是200-400nm紫外光，推荐使用365nm紫外光源。

四、固化条件:

500-1000W高压汞灯,主要波长365nm；固化条件 800mj/cm²

定位：5秒，固化30秒（具体固化依所使用的光源、胶膜厚度及被粘材料测试为准）

Solder joint protection UV adhesive is a one component UV curable adhesive. Under the irradiation of UV light, it can quickly harden and produce strong bonding properties. The product has excellent flexibility, low odor, good surface dryness, fast curing speed and high bonding strength. It is typically used in the bonding, sealing, insulation, fixation of electronic components, inductors, capacitors, circuit boards, cables, data lines, connectors and other products, as well as the tin fixation protection of solder joints. The water curing time of UV glue is short, which can improve the production efficiency and enhance the tensile strength of solder joints, Suitable for automatic production line operation

The characteristics of solder joint protection UV adhesive are impact resistance, shock resistance, moisture resistance, fast curing, good surface dry and deep curing ability; Low odor, almost no stimulation, not easy to sensitize; Good fluidity, no drawing, no vertical flow, good extrudability; Good flexibility, adhesion to metal and plastic.
