【 JJY 】 Precautions for Using SMT Patch Solder Paste

Solder paste isSMTThe indispensable processing materials in surface mount technology (SMT) processing will have a direct impact on their qualitySMTThe quality of surface mount technology (SMT) processing.SMTThe processing quality of the processing plant is reflected in the small details of all aspects.Solder pasteThere are also many precautions for its use. Below, JJY Solder Paste Manufacturer will briefly introduce to you the precautions for using solder paste:

1. Solder paste should be stored in an ice box, and the storage temperature should be controlled at2°C-10°CWithin the range, the shelf life of unopened solder paste is calculated from the production date6In a month, the solder paste opened was24When it is a child, I would like to remind everyone not to place it in a spot where sunlight can reach.

Second, the solder paste must be warmed up before use. Warming up means leaving the solder paste at room temperature to allow its temperature to rise naturally,To meet the usage requirements.

Iii.SMTThe main reason for the warming up of surface mount solder paste is that if it is taken out of the refrigerator and used directly without warming up, air will condense into water droplets on the surface of the solder paste andSMTTin beads are produced during the processing. Moreover, the solder paste has a relatively high viscosity at low temperatures and cannot meet the printing requirements. It must be warmed up before use.

After taking out the solder paste, immediately close the inner cover and press it down forcefully to squeeze out all the air between the cover and the solder paste, so that the inner cover can be in close contact with the solder paste. After confirming that the inner cover has been tightened, screw on the outer large cover.

V. When the solder paste on the printing press is no longer used, the remaining solder paste should be immediately collected into an empty bottle. During the storage process, it is necessary to ensure that it is completely isolated from the air. Under no circumstances should the remaining solder paste be mixed into the bottle of unused solder paste. Therefore, when taking solder paste, we should try to accurately estimate the amount of solder paste used to ensure that we take only as much as we need.
