The phenomenon of tin explosion and tin explosion means that when the high-temperature soldering iron head touches the solder wire during the soldering operation, it will make a cracking sound, and at the same time, the molten tin will splash and pop out some small tin beads of bright color. Tin phenomenon.

The flux-cored solder wire leaves a channel inside for placing the rosin flux, which can better help product soldering. The solid core solder wire, as the name implies, refers to the solid core of the solder wire, and no rosin flux is poured in the middle, hence the name solid core solder wire.

Check the wire feeding speed of the tin wire. Under normal circumstances, the wire feeding speed should be less than 60mm/s. If the wire feeding speed is too fast, the tin wire may be pushed to the PIN before it can be melted, which may easily cause tin blocking.

The phenomenon of exploding tin and exploding tin means that when the solder wire (tin wire) is in the process of welding, when the high-temperature soldering iron tip touches the solder wire, it will make a cracking sound, and at the same time, small tin beads will burst out. It is the phenomenon of fried tin.

1. The large amount of moisture contained in the air will cause the solder wire (tin wire) or circuit boards, welding tools and other items to be damp. During the manual soldering process of the solder wire, the solvent in the flux will volatilize, causing the board surface to cool down, and the air in contact with it will be condensed to form a mist that condenses on the board surface.

The main component of solder paste is a paste made by mixing metal powder and flux. Can the electronic components be well attached to the circuit board during the production process of the SMT manufacturer? The quality of lead-free solder paste is a very critical control point. A suitable solder paste can not only improve the soldering yield of the production line, but also greatly improve the soldering performance of the circuit board, which is the most reliable guarantee for the soldering quality of the circuit board.

Validity period of solder paste: When sealed and stored at 0℃~10℃, the validity period is 6 months. (Note: Before putting the new solder paste in the refrigerator, attach the status label, date it and fill out the solder paste entry and exit control form.)

When everyone uses lead-free solder paste for homework, there are always a lot of bubbles. Air bubbles in solder joints not only jeopardize the stability of the solder joints, but also increase the probability of component failure. When applying lead-free solder paste, the air bubbles in the solder joints are the heat storage places for electronic devices when they work, and the heat energy generated when the electronic devices work will accumulate in the air bubbles, resulting in the ambient temperature of the solder joints not being able to be output smoothly according to the solder joints. The longer the run time, the more thermal energy is accumulated and the greater the damage to the stability of the solder joint.
