4.FPC manufacturer introduces the requirements and precautions of FPC surface mount.
Supply stable performance of FPC producer is introduced in the flexible printed circuit board (FPC) on the technological requirements of SMD in the miniaturization of electronic products development, quite a number of consumer products, SMT, because the assembly space, the relationship between the SMD on FPC soft plate is pasted on the complete machine assembly, therefore, FPC on SMD surface-mount has become one of SMT technology development trend.Specifically, there are several aspects to the process requirements and attention points of FPC surface mount.

Pay attention to the details of the routine installation,
FPC factories introduce FPC surface-mount introduce FPC soft board the characteristics of the conventional SMD SMT is the less demanding in terms of accuracy, and software is relatively small, the number of varieties of components is given priority to with resistance capacitance or an individual element.FPC manufacturers emphasize that the printing of solder paste should be noted that the FPC is positioned on the printing plate and is usually printed with small semi-automatic printing presses.SMT, specific methods usually can use manual pasted on the position precision of some individual components also can use manual placement machine SMT, and generally adopts the reflow soldering process, special circumstances can also be used spot welding. 

Note that the high - precision mounting should adopt advanced equipment and adjust the corresponding parameters.
The FPC manufacturer introduces the paste printing machine, and the printing machine is best equipped with an optical positioning system so that the welding quality can be guaranteed. FPC manufacturer also found the FPC fixed on the plate, but a lot of time will produce some small gap, so pay attention to the equipment parameters set for SMT precision printing effects, etc, will produce more significant impact, so the process must be good control, strict requirements. 

Pay attention to the accuracy of the paste printing details.
Service good reputation FPC producer introduced on because cells when printing plate loading FPC, FPC soft board with other materials can make the height and positioning plate plane, so must choose when printing the elastic scraper.The FPC manufacturer also reminds the paste composition to have a great impact on the printing effect, and it is necessary to choose the appropriate solder paste. In addition, the printing template with the corresponding method should be specially treated. 

Above is the FPC FPC manufacturers to introduce the SMT process included several aspects of the requirements and matters needing attention, in addition, in order to be better consistency can be achieved when mass production, so the requirement with good quality and more advanced equipment.FPC manufacturer also remind FPC soft plate fixation should be printed patch to the reflow soldering on the plate with all the way, so to adjust the corresponding thermal expansion coefficient is small degree to be able to get a better welding effect.
