PCBA Knowledge:
Thermal energy is an indispensable condition for welding. In soldering, the effect of thermal energy is to spread the solder to the component and raise the temperature of the weldment to a suitable soldering temperature. In order to form a metal alloy with the solder.
Welding time refers to the time required to perform physical and chemical changes during the welding process. It includes the time when the weldment reaches the soldering temperature, the melting time of the solder, the time the flux acts and the time it takes to form the metal alloy. The soldering time of the circuit board should be appropriate. If it is too long, it will damage the soldering parts and devices. If it is too short, it will not meet the requirements.
About the welding method of the circuit board,.for the welding method of the small batch,manual soldering is used. For large-volume electronic products, immersion soldering and wave soldering are used.
In the whole welding process, the manual welding method is used, and the tools used are mostly electric soldering irons. The electric soldering irons are divided into external heating type electric soldering irons and internal heat type soldering irons. In the batch circuit board assembly process, the equipment used is a wave soldering machine.(Pcb Manufacturing And Assembly)
