The idea that micro-innovation is a parody, like copying technology be considered mere "Cottage". Experts believe micro-innovations can be interpreted two, an emphasis on "micro", this understanding talked of micro innovation more innovation on the surface, and another that micro innovation should be the mode, with emphasis on "innovation" above, just take the small steps on the road of innovation, continuous innovation, faster pace. PCB copy Board is a gradient of the accumulation of micro-innovation technology by reverse techniques to master other advanced technology research and development, and on the basis of a new breakthrough, give people a quick offer of technology products. Like recently Samsung phone S3 Shang, we know intelligent phone power, so screen bright a time on will dark off, but everyone often in top reading, see with see with screen dark off has, so can in phone circuit board Shang do very small of changes, in he dark off zhiqian will put photo as head open, then phone like people as see about user, found you is see on not put screen lamp off. Innovation is the essence, but very small, in the original circuit board with flights on the basis of secondary development to solve the problem now.
