The choice of soldering iron tip is very important it not only affects the soldering effect and the lofe of the
soldering tip, but more importantly, it will play a greater value according to the package form of different chips.
The main factors to consider choose soldering tip as below:
1) Select the soldering tip size according to the solder joint size and the solder joint density ;
2) Select the soldering tip shape as per the type of soldering element, the ease of solder joint contact, and the amount of tin required.
Soldering tip life is determined by solder joints, and it is also connect with the thickness of the plating layer on the tip head.The thicker the plating layer, the longer the tip life. But the thermal conductivity efficiency will be reduced greatly. For the same lead free soldering tip under the same temperature,
The main raw material for soldering tip is copper. And the best thermal conductivity of copper is red (purple) copper. Copper, as a thermal conductor, is the main component of the soldering iron tip, accounting for about 90% of the soldering tip material. The red copper thermal conductivity is good, which helps the soldering iro tip to heat up quickly. However, in order to get more profit some factory use
1. First adjust the temperature to 300 ° C, clean the tip with a cleaning sponge, and check the condition of the tip.
2.If the soldering tip tin plating layer contains black oxide, kindly plate new tin layer, then
clean the soldering tip with a cleaning sponge until the Oxide is completely removed,then plate with a new tin layer.
The melting pool temperature directly affects the welding quality, the melting pool temperature is high, the molten pool is larger, the fluidity of molten iron is good, and the molten iron is easy to melt.
In general, tin furnace is a welding tool used in electronic welding. For discrete components PCB welding consistency, easy to operate, fast, high efficiency, is your production and processing of good helpers.
1. before inserting the power supply, the switch should be positioned in the closed state, and the power supply voltage is suitable for the machine to be used. When the electric screwdriver is not used or the power is broken, the plug should be put off.
