Baby design background: as an electronic engineer, if you only write a few sentences of the programme, will not take the soldering iron welding, really can not say. Now a lot of students or just out of the engineers, only want to learn ARM, learn FPGA, learn Linux, not to mention welding QFP100 this kind of dense foot IC, is welding resistance and capacitance will not be or weld bad; or will only weld some plug-in components. In the actual product, the vast majority of devices are SMD. In the debugging stage of R&D samples, they are all soldered by hand, do you have the ability to solder?

If you don't build up step by step, you can't build a thousand miles; if you don't build up small stream, you can't build an ocean! It's okay if you don't know how to solder, now you can start to learn from the simplest 1206 0805 0603 package resistance and capacitance!
