What causes the solder paste to be too thin in SMT printing operations?

inSMTIn printingSolder pasteIt is a material used for soldering electronic components, usually composed of tiny solder particles and fluid flux, inSMTIn printing operations, throughout the entire application process of solder paste, it is very likely that the solder paste will be too thin. What causes this situation? Regarding this issue, the following is an analysis provided by Shenzhen JJY Solder Paste Manufacturer for everyone:

1Check the viscosity of the solder paste and the temperature in the solder paste production workshop. The indoor temperature must not be too high28℃When the temperature is too high, the viscosity of the solder paste decreases. If the indoor temperature is normal, it can be determined that the viscosity of the solder paste itself is too low.

2The temperature rise time of the solder paste is insufficient, usually four hours at room temperature.

3If the solder paste is not stirred for enough time, mix it with a solder paste mixer1-3Minutes. Manual stirring is a must3-4Minutes.

That's all.SMTThe reasons for the solder paste being too thin in printing operations. When such a situation occurs, everyone must respond rationally and conduct a targeted analysis of the above reasons. If it is indeed a quality issue of the solder paste itself, the relevant distributor should be required to prepare it to meet the requirements suitable for one's own printing.
