哪些常见的胶水适合焊点保护呢？各有哪些特点？

焊点保护胶水是一种涂覆在线路板焊接点上的封装密封接着保护材料，用以增强上锡点的抗拉强度、接着强度、耐久性、绝缘密封特性等，是一种必要的电子材料；那么，一般有哪些胶水适合于焊点保护呢？下面跟着华创新材的小编一起来了解一下吧：

1、黄胶水，黄胶一般应用于元器件固定也可用于焊点补强，强度不高普通补强可以，环保要求不高可以用，价格便宜，一般为单组份自然固化，操作简便；但含有溶剂气味较大。

2、单组份硅胶，通常应用于线路板元器件固定焊点加固补强，固化后弹性体，环保，耐温高耐老化，粘接强度比黄胶强，成本比黄胶高一点，

3、UV胶水，焊点补强加固的UV胶，跟线路板，金属，塑料都有很强的粘接力，固化速度快UV光固化15秒左右，环保耐耐老化，应用于单点焊线，排线等理想的加固补强，一般比较常用。

4、环氧树脂AB胶水，此类型固化快，一般最快可以做到3-5分钟，粘接力耐温性耐老化及耐化学品特性都非常好，用具有较灵活的可调节性，可依要求进行不同的特性改良

5、单组份环氧树脂胶，此类型特性同第4点，区别在于属于加温固化体系，其耐热性及粘接强度相比AB环氧树脂更高，适用于一些要求较高的产品。

此外，还有一些比如PU胶，热熔胶等也可以做一些低要求的焊点保护，其具体选用，需要依据自已产品的特性要求及操作性进行合理选用，

Solder joint protection glue is a kind of packaging and sealing protective material coated on the solder joint of circuit board, which is used to enhance the tensile strength, bonding strength, durability, insulation and sealing characteristics of the solder joint. It is a necessary electronic material; So, which glue is suitable for solder joint protection? Let's follow huachuangxincai's editor to learn about it

1. Yellow glue, yellow glue is generally used for fixing components, but also can be used for solder joint reinforcement, the strength is not high, ordinary reinforcement can be used, environmental protection requirements are not high, it can be used, the price is cheap, generally single component natural curing, easy to operate; But it contains solvent and has strong odor.

2. One component silica gel is usually used to reinforce the fixed solder joints of circuit board components. After curing, it is an elastomer with environmental protection, high temperature resistance and aging resistance. The bonding strength is stronger than xanthan gum, and the cost is higher than xanthan gum,
