Introduction and principle of high frequency lead-free soldering station
Introduction
After the electronic products are scrapped, the lead in the PCB solder is easily soluble in oxygen-containing water. Pollution of water sources, damage to the environment. Solubility makes it accumulate in the human body, damage nerves, cause sluggishness, high blood pressure, anemia, reproductive dysfunction and other diseases; excessive concentration may cause cancer. Cherish life, times require lead-free products. As an important link in the manufacture of pCB circuit boards, soldering must be lead-free, so high-frequency lead-free soldering stations came into being.
working principle
Compared with constant-temperature soldering stations, high-frequency lead-free soldering stations generally use high-frequency eddy current heating, with fast heating and return speeds to achieve lead-free soldering, and the power is generally as high as 90W-200W.
Precautions
Temperature management of the soldering iron tip
Depending on the solder being used, it is important to select the most appropriate tip temperature setting. Before working, it is necessary to measure the temperature of the soldering iron tip with a soldering iron tip thermometer.
Use positive high-quality soldering iron tips
The counterfeit soldering iron tip, the hole diameter (into the heating core) is large or small, and the thickness of the casing is also different. These all cause the performance of the electric soldering iron to be unable to play, and sometimes cause the cause of the electric soldering iron failure.
Use the matching handle heating element
Because the heating principles of high-frequency soldering stations and constant-temperature soldering stations are different. So the handles between them are not universal.
