In recent years, in order to maintain sufficient competitiveness and anti risk ability in the complex international economic environment, besides the management level, mechanism structure and technical strength, the most important, fundamental and deep-seated factor is enterprise culture.
How to embody the uniqueness of corporate culture? Different cultural concepts, different levels of enterprise gap is obvious. Two of the most influential international enterprises in SMT industry pay attention to Chinese education and cooperate with famous universities in China. Global instruments, an international famous placement machine manufacturer, and Wallace technology, which focuses on the high-end technology of chip processing software, are two top enterprises in the industry. They cooperate with Tsinghua University to jointly devote themselves to personnel training. They do not focus on the immediate, nor pursue direct return. They are more concerned with corporate image, cultural concept, talent strategy and future development. Can our local SMD processing enterprises calm down and seriously think about it during the adjustment period?
The SMT industry will be in a state of adjustment period, and whether or not it is aware of this adjustment, the status is beyond doubt. However, the adjustment is different from previous years. For the electronic information industry, there are three unprecedented opportunities in the industry: the increasingly mature automotive electronics industry; the 3G mobile phone with unlimited prospect; and the Olympic business opportunities represented by digital color TV.
We introduce the basic process elements of SMT processing. First of all, silk screen printing, mounting, curing, reflow soldering, cleaning, testing, repairing, silk screen printing: its function is to leak the solder paste or patch adhesive onto the pad of PCB, so as to prepare for the welding of components. The equipment used is screen printing machine (screen printing machine), which is located at the front end of the SMT production line.
The second element of the basic process elements of SMD processing is dispensing process: dispensing process is to drop glue to the specific position of PCB board, and its main function is to fix components to PCB board. The equipment used is a dispensing machine, which is located at the front end of the SMT processing line or behind the detection equipment. Mounting: its function is to accurately install the surface assembly components to the fixed position of PCB board. The equipment used is a mounter, which is located behind the screen printing machine in the SMT processing line.
The third element of SMT processing technology is the curing process: the function of curing is to melt the SMD adhesive, so that the surface assembly components and PCB board are firmly bonded together. The equipment used is curing furnace, which is located behind the mounter in the SMT processing line. Reflow soldering: its function is to melt the solder paste, so that the surface assembly components and PCB board are firmly bonded together. The equipment used is reflow oven, which is located behind the mounter in the SMT line. The fourth is cleaning: its function is to remove the harmful welding residues such as flux on the assembled PCB board. The equipment used is a cleaning machine, the position can not be fixed, can be online or not.
