Yesterday my sister asked me whether i need the used hard disk or not. She said if i don’t want it she will throw it away. I quickly replied, yes of course i need it because i could salvage some SMD electronic parts from the board. Besides getting the SMD parts from the hard disk, i could also get this hard disk for my future students/participants to practice on how to solder/desolder SMD components especially the IC’s. I also buy over those bad computer motherboards (with cheap price) from my computer dealers in order to salvage the parts too.
Although i don’t use the parts everyday but if you really need SMD component for a particular circuit in electronic equipment then this is the time where you can get some spare (hopefully) and reference too.
