Soldering iron mouth maintenance:
New the first use of the soldering iron, soldering iron shall not be used, need to be on the soldering iron tsui plating a layer of solder, the method is: use clean the solder iron tip file file, press on the power, the temperature gradually increased, with resin coating on the soldering iron tsui; Rosin smoke, soldering iron tsui started to melt the solder, the soldering iron tip on the abrasive paper with small amounts of rosin and solder every surface grinding, grinding to, so you can make the solder iron tip on the plating a layer of solder to strengthen soldering iron tsui life.
Mechanical principle of the soldering iron tip:
Virtual welding is only a small amount of tin solder welding, causing poor contact, when when broken. Tack weld is refers to the surface like welding, but did not actually on welding, sometimes a drawing with the hand, lead can be pulled out from the solder joints. In both cases will bring the debugging and maintenance of electronic production. Only through a lot of welding, serious practice, to avoid the two cases.
When the welding circuit board, must be good control of time. Is too long, circuit board will be burned, fall off or copper foil. Remove the device from the circuit board, the soldering iron head can be on the spot, after being solder on the tin melting, pull out components. The temperature of the soldering iron and soldering iron head size, shape, length and so on all has the certain relations. When the volume of a soldering iron head is larger, the holding time is longer. In addition, to adapt to the requirement of different welding materials, welding head shape is different, common cant have a cone, a chisel, round shape and so on.
