YIHUA 900M Series Soldering Iron Tips K I IS Pure Copper Lead-Free Replacement for 936 939 907 Solder Station Handle Accessories

 Product Usage:Used for solder melting tinSecond, product features:1 oxygen-free copper production  environmental protection and lead-free corrosion resistance and effectively prevent oxidation2 fast heat transfer, product quality and stability, heating faster3 the use of lead-free plating treatment to ensure a longer life, color bright and shiny texturePrecautions for useA try to use low-temperature welding, reduce the life of the soldering iron tip    If the soldering iron tip temperature exceeds 470 ℃, its oxidation rate is twice as fast as 380 ℃B  Do not apply too much pressure     In the welding, please do not apply too much pressure, otherwise it will make the iron head damaged and deformed, as long as the iron head fully in contact with the soldering point, the heat can be transmitted, in addition to choosing the right iron head can also be better welding.C often keep the soldering iron tip on the tin    This can reduce the oxidation frequency of the soldering iron head, making the iron head life extension. After use, should wait for the soldering iron head for the slave slightly reduced before adding new solder, so that the tin layer has a better anti-oxidation effect.D  Keep the iron head clean, clean up the oxides in time     If there is black oxide on the soldering iron head, the iron head may not be on the tin, this time must be immediately cleaned up, clean up the soldering iron head temperature jumped to 250 ℃ and then clean sponge to clean the soldering iron head, and then on the tin, and constantly repeat the action, until the oxides cleaned up so far.E  Selection of low activity solder resistRound head type (B)Characteristics: Round tip is non-directional, the entire front of the tip can be solderedApplication: Wide range of use, suitable for general welding, regardless of the size of the soldering joint, can be usedSharp tip type (I/SI/IS/LI)/Horseshoe tip type (2C/2CF/3C/S8)Characteristics: Tiny tipApplication scope; suitable for precision soldering such as SMD machine, or for the situation of narrow space, can also be used to correct the soldering chip tin bridgeKnife tip type (K)Features: the use of knife-type part of the welding, vertical or pull welding or welding can be, belong to the multi-purpose soldering iron headApplication scope; suitable for SOJ, PLCC, SOP, QFP power supply, grounding part of the components, correction of the tin bridge, connectors and other weldingFlat head type (1.2LD/1.2D/1.6D/H/1.8H)Characteristics: Soldering with the tip part, according to the need to choose a different size and thickness of the soldering iron tip for soldering.Application scope; suitable for different occasions, generally suitable for more tin, large area, thick terminals, large solder joints and other environments
