An explicación de cómo el tamaño y potencia de an eléctrico soldadura hierro difiere
El eléctrico soldadura hierro es un vital herramienta en el eléctrico reparación proceso, pero muchos mantenimiento trabajadores que tienen solo recientemente encontrado el soldadura hierro son inconscientes de el estándar que se usa para determinar el poder de el eléctrico soldadura hierro hierro durante el soldadura proceso , y ellos con frecuencia viajar el globo con solo uno soldadura hierro. El más obvio efecto es el efecto es subpar como un resultado de negligencia En Soldadura Hierro Potencia Selección.
The printed wires will fall off the substrate and the components are easily burned when the power of the electric soldering iron is too high (generally, when the junction temperature of the diode and triode exceeds 200 degree , it will burn out). Conversely, when the power of the soldering iron is too low, the soldering tin cannot fully melt, the flux cannot volatilize, the solder joints are not smooth and firm, and it is simple to produce false welding. It is typically used to weld integrated circuits, printed circuit boards, CMOS circuits, decorative transistors, IC recorders, TV sets, and for routine circuit investigations (20W is usually sufficient). It is also used to repair vacuum tube machinery, such as amplifiers and vintage instruments.The proper power is 35W, while the external heating type requires 45W. For the internal heating type and the exterior heating type, the wiring for the huge transformer for welding and the grounding trunk line on the metal base plate is 50W and 75W, respectively. Use an electric soldering iron with an external heating element that is greater than 100W if you want to weld metal products. Amateur radio operators can, if the circumstances allow, equip themselves with a 2OW internal heating type, a 35W internal or external heating type, and a 150W external heating type electric soldering iron, allowing them to essentially satisfy a variety of welding needs.
Plomo soldadura, que tiene a composición de 63 por ciento tin and 37 percent plomo y a fusión punto de 183 grado , es el tipo de soldar que es más frecuentemente usado. Sin plomo soldar, on the other hand, has a composition of 99 percent tin and a flux content of around 1 percent , and its melting point is 227 degree . plomo soldadura tiene las ventajas de tener un bajo punto de fusión 2c ser simple para soldar, y ser barato , pero es no ecológico amigable y plomo es peligroso para humanos , así usted debe bien lavar sus manos después de la soldadura. Para establecer a específico distancia entre el cabeza y el soldación mientras soldar, it es mejor desgastar a máscara o estar en an area con bright light. Lead-free solder is being employed in companies for machine welding as awareness of environmental protection has increased . It is easy to understand why lead-free solder, which is frequent challenge to melt when fixing imported electrical items, has a high melting point.
The electric soldering iron is an electric heating tool that, if activated, can produce a high temperature of roughly 250 degree . Actually, heat conduction occurs throughout the soldering process while using an electric soldering iron. The solder absorbs the heat from the soldering iron tip as it comes into contact with the soldering surface, melts and flows, and forms a bright and circular solder junction due to surface tension. Metals are good heat conductors, thus during the welding process, heat transfer happens more quickly.The temperature of the solder will decrease somewhat during the melting process as a result of heat loss from the soldering iron tip. The solder junction has to absorb more heat if it is larger in area in order for the solder to melt. The temperature lowers more quickly if the soldering iron tip is small and stores less heat, and by the time heat is generated owing to the soldering iron core's weak power, it is too late to restore the heat that has been lost. The solder does not melt or does not melt completely is currently the most logical phenomenon. In this situation, welding requires the use of a high-power soldering iron.Instead, if the welded parts are small, it is not necessary to use a high-power soldering iron; however, if it is, it is important to pay attention to the welding time because excessive heat can easily damage the circuit through which the current flows and the circuit board, causing the printed copper foil to come off. There is no exact quantitative need; the soldering iron's specific power is sufficient. The easiest way to select a soldering iron that suits you is to look at maintenance personnel's long-term job experience accumulation.
