Soldering printed circuit boards through hole material is tin-lead alloy. Its melting point is relatively low. The melting point of eutectic solder is only 183 °C. It is the most common welding technology used in the electronics industry.
Soldering has the following characteristics:
(1) The melting point of the solder is lower than the melting point of the weldment.
(2) When welding, the weldment and the solder are heated to the optimum soldering temperature, the solder is melted and the weldment is not melted.
(3) The formation of the solder depends on the molten state to wet the soldered surface, and the capillary enters the gap by capillary action to form a bonding layer, thereby achieving the bonding of the weldments.
