With the growing size of electronic products, the use of surface mount devices is also increasingly widespread, in this demand, the placement machine as a major production equipment in the importance of electronic manufacturing has become increasingly prominent. China's mainland electronics manufacturers from the late eighties of last century began to introduce from the foreign placement machine SMT manufacturing, but then the scale is not large, mainly some TV factory for color TV tuner production, so the placement machine market The real prosperity is actually from the mid-nineties.
