he production technology of the soldering iron head
Soldering iron head generally manufactured copper material. For protection under the condition of the high temperature of welding were not oxidize, often used the welding head after plating processing, some welding head with not easy oxidation of alloy material. New welding head before formal welding should be tin plating processing. Way is to use sand paper burnish it clean, rosin water, then immersed with solder on the hard tool (e.g., wood) grinding repeatedly, let each face all tin plating. If using for a long time, welding head has oxidation occurs, the light with a small file file to surface oxidation layer, after showing red light by new welding head with tin. When using only a soldering iron, can use different shades of the soldering iron head inserted heater to control temperature. Soldering iron head out from the heater, the temperature of the soldering iron head is relatively lower, whereas the higher temperature. Also change the size and shape can be used to achieve the purpose of regulating temperature. Soldering iron head is fine, the higher the temperature; More thick, the relative humidity is more low.
Soldering iron head the analysis of the causes of corrosion
Soldering iron head installed (tip) corrosion factors, namely welding head corrosion factor analysis:
Soldering iron head, iron nickel chrome plating is tin, iron plating under high temperature is the key of the quality of welding head, iron and tin will generate a kind of alloy, the alloy will dissolve in a liquid solder, lead to welding head surface coating iron loss, the phenomenon is the soldering iron head punch. Lead has inhibitory effect of this kind of alloy produced by speed, of course can't completely put an end to. In addition, the composition of tin in lead-free solder is higher, the more serious corrosion; The higher the temperature, the faster corrosion. This is why the lead-free soldering iron head is faster than lead welding with factors.
The overall structure of the soldering iron tsui of environmental protection
Environmental protection soldering iron tsui, also belong to lead-free soldering iron tsui. Environmental protection soldering iron tsui on shape design using special forming machine, ensure the size precision. Lead-free alloy plating is close-grained, iron specialty service life.
Green solder iron tip the entire surface using special material processing, to ensure that the material is not due to the high temperature black. Cutting-edge tin plating processing, welding
When the tin easily, and effectively prevent oxidation, high temperature can reach 480 degrees, normal use to ensure more than 20000 solder joints.
Green solder iron tip can also according to customer demand for personalized custom.
Lead-free soldering iron head welding is introduced
Compared with the traditional leaded solder, the lead-free welding technology principle is by some mixture of alloy to replace the original lead, lead-free soldering iron head is adopted to improve the welding. This is welding characteristics of this kind of alloy melt temperature slightly higher than lead solder. With Sn/Ag alloy as an example, its melting temperature is 221 degrees Celsius, higher than that of leaded solder melting temperature 183 degrees Celsius, and the other some lead-free solder Sn/Ag/Cu melting point is 218 degrees Celsius, Sn/Ag/Cu/Sb melting point is 217 degrees Celsius. Lead-free soldering iron head corrosion, high temperature will speed up the welding head to increase equipment downtime and accessories replacement cost. When lead-free soldering iron head left smart iron stand, lead-free flipping steel-toed temperature quickly return to work automatically.
