The purchase of parts from the self-welding friends noticed that the universal board kit does not solder the components like the PCB board kit. This requires you to plan the placement of the components and the wiring, which is very capable of exercising the welding ability. The basis of welding (read the schematic), such as the parents who are not sure about themselves, please consider.
