Circuit boards, electronic components of the welding and assembly
Welding tools: welding small electronic components with 20w internal combustion electric iron. Solder: the middle of the rosin with the solder wire. Welding methods: (1) new electronic components and circuit boards are tinned, can be directly welded. Old components to remove the surface oxide, rust, dirt and so on. (2) first heated electric soldering iron, on the junction of the pin and the circuit board and the plane into a 45 degree angle. (3) heating 3-5 seconds and then put the solder wire at the junction, until the solder fully melted and fully combined, remove the soldering iron solder wire. (4) with the blowing method is the rapid cooling of the solder joints. (5) solder joints as small as possible, solid. (6) welding time as short as possible. Welding Note: (1) electric iron ground wire and power ground wire phase, to prevent the electric iron leakage accident. (2) Wrap the lead wire with tweezers when welding to prevent damage to the component due to excessive temperature. (3) solder is not solid before the rock components, to prevent false w |
