What is the maximum warming time for SMT solder paste?

SMTSolder paste warming is a very important step in the production process of the electronics industry, and its purpose is to enableSolder pasteRestore a certain viscosity to enable surface mount components to adhere more firmlyPCBBy doing so, the quality and reliability of electronic products can be improved. During the warming process, it is necessary to pay attention to controlling the warming temperature and time to prevent excessive warming from causing evaporation and oxidation of the solder paste. The following solder paste manufacturer will explain it to you:

ForSMTThe time for solder paste to warm up should generally not exceed the maximum24Hours. Because an overly long warming time will cause the solder paste to age, thereby affecting its application effect. In addition, different brands and modelsSMTThe warming time of solder paste may also vary and needs to be adjusted according to specific circumstances.

Not only the warming time but also the warming temperature need to be adjusted according to specific circumstances. In actual production, it is necessary to rely onPCBThe tempering temperature is determined by factors such as the thickness of the board, the type, density and size of the surface mount components. Under normal circumstances, the reheating temperature is150℃It is advisable to keep it on either side. Excessively high temperatures can cause damage to components orPCBThe board is aging. In addition, when warming up, attention should be paid to controlling the uniformity of the temperature to avoid excessive temperature differences.

inSMTDuring the warming process of solder paste, apart from time and temperature, the influence of other factors should also be taken into consideration. For example, during the reheating process, the environment should be kept dry to avoid the influence of moisture on the solder paste. At the same time, it is necessary to avoid warming upPCBThe vibration of the board and components should be avoided to prevent any impact on the quality of electronic products.

To sum up,SMTDuring the warming process of solder paste, it is necessary to pay attention to controlling the time, temperature and other factors to ensure the application effect of the solder paste and the quality of electronic products. In specific operations, it is necessary to consider the brand and model of the solder pastePCBThe temperature recovery parameters are determined and adjusted based on factors such as the thickness of the board and the type, density and size of components. It's the only way to be sureSMTThe effect of solder paste warming is the best, thereby improving the economic benefits and production efficiency of the entire production process.
