The secret to a long soldering iron tip life?

For the soldering iron industry, the length of time of use has always been the core index to measure the quality of the soldering iron. Research out both good and can be used for a long time normal use of the soldering iron head, but also many soldering iron head over the years has not been exploring the direction.
At present, the more mature program has been to keep the plating layer thickness unchanged, as far as possible to change the density and uniformity of the plating layer. In this way of thinking, the stability of the plating solution and the composition of the goodness is the first step in the effort. At present, the plating solution is improved by the addition of trace ingredients, such as nano additives. This step is a great test of technical strength, always after numerous attempts to achieve an addition ratio that is considered optimal at the time.


The second step is to find the thickness of the plating layer and temperature and the golden mean point. Thick alloy plating, corrosion resistance time will be long, but his side effect is that the heat conduction will be weak. So how to balance the two both in the premise of not affecting the speed of heat conduction, the thickness of the plating layer as much as possible.
In the pursuit of environmental protection under the premise that there is another attempt in progress, that is, the use of welding process to the high-purity alloy iron and copper welded together, the working part is processed from the alloy iron, the back end of the heat conduction or the use of copper's excellent performance. The difference is that the former use of the copper base outside the parcel plating layer, the latter is divided into two parts, in terms of corrosion resistance, the latter certainly has an absolute advantage in the transfer of heat, the limitations are also very obvious, in the temperature precision requirements of a slightly higher soldering conditions can not be well adapted to be improved.
