What should I do if I find the SMT solder paste a bit thin during use?

Recently, a customer inquired about what to do if they found the solder paste was a bit thin during the soldering process. If the solder paste is too thin, it may result in the inability to obtain good solder joint quality during the soldering process. Today, Shenzhen JJY Solder Paste Manufacturer will briefly introduce to you several temporary solutions as follows:

1Stir and mix

Use a stirring rod or a dedicated solder paste mixer to thoroughly stir and mix the solder paste. This helps to evenly disperse the metal particles in it, making it more viscous, but the stirring period should not be too long.

2Refrigeration

Put the solder paste in the refrigerator's crisper drawer and chill it for a while. Low temperature can make the solder paste more viscous, but the time for it to warm up after refrigeration should not be too long. It is fine when it is close to the ambient temperature.

3Return it to the solder paste manufacturer for readjustment of viscosity.

The above is a brief analysis provided by Shenzhen JJY Solder Paste Manufacturer for everyoneSMTSome temporary solutions for finding the solder paste a bit thin during the soldering process. It should be noted that different solder paste brands and types may have different characteristics and usage requirements. Therefore, it is best to refer to the merchant's instructions or contact better suggestions. In addition, to avoid affecting the soldering quality, it is recommended to conduct some small-scale experiments and tests before actual production operations to ensure that the adjusted solder paste meets the required viscosity and performance.
