Quick turn pcb assembly

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 welding false welding. (4) welding a variety of electrical components, the first large and small after the principle. (5) welding electronic components and integrated circuit chip, the electric iron should be grounded, or cut off the electric power after the soldering iron. To prevent the soldering iron induced voltage to damage the chip. Evaluation elements: (1) the use of the right way to complete the electronic circuit welding and assembly. (Tools, solder preparation, welding steps and methods.) (2) by the instrument test, the circuit function is correct. (3) check the appearance of electronic components arranged neatly smooth and no solder joints.
