Let the detergent is completely dry, and then painted a mixed but thinner, turpentine for the printed circuit board assembly from the soldering as a company can instantly leg devices. Use sandpaper, rubbing lightly to remove dirt and wax laiat or if you prefer the convenience, it may use the knife to gently scrape the device but do not scrape the leg strength of tin coating layer, until all are connected, making difficult to heat with the printed circuit board and solder the legs straight at the device to simultaneously pay the solder melting piece of work around when the lead. Soldering iron and solder gradually withdraw out of the work piece is finished with the power cord connected to the printed circuit board.-Peel the wires, fit. It should not be too long or short, stripping.-Lead coating against the late cord first so that the printed circuit board into the soldering easier.-Bring the power cord inserted and then soldered to the PCB solder soldering equipment like a power cord with a primary (Terminal)
