A smt pick and place machine Qihe India SMT PNP LED Expo exhibition review

Qihe India SMT PNP LED Expo exhibition review

Just last week, we completed a three-day fair : 2022 Light + LED Expo India.We showed the popular models PNP smt pick and place machine QL41,TVM925,TVM802AX and reflow oven machine such as QRF320 ,etc.
In fact, we are satisfied with the final presentation of this exhibition.
At the scene, we even heard customers and friends from afar sigh that this trip is worthwhile and has a lot to gain and some clients order signed on site.
The booth was full of people, and many old customers also visited the Qihe booth and gave them high praise! We will make persistent efforts to provide customers with more good products!
Let the Qihe brand and high-quality products become a household name!

WHAT IS SMT pick and place machine?

SMT (Surface Mounted Technology) is a comprehensive system engineering technology, which covers substrates, design, equipment, components, assembly processes, production accessories and management. When it comes to SMT pick and place machines, the automatic SMT production line requires automatic loading and unloading machine, automatic solder paste printing machine, placement machine, reflow soldering machine, AOI inspection equipment, connecting table, etc. For these SMT assembly line equipment, Qihe SMT can offer you machines in prototype SMT line, small SMT production line, mass production SMT line at low SMT line cost. Contact us now if you are interested.


With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.


There are mainly three steps in SMT assembly line process flow: solder paste printing, components placement and reflow soldering.

  1. Solder Paste Printing

Its function in SMT line process is to print the solder-free paste on the pads of the PCB to prepare for the soldering of the components. The equipment used is a screen printing machine, located at the forefront of the SMT production line.

  1. Components Placement

Its function is to accurately install the surface mount components on the fixed position of the PCB. The equipment used is a placement machine, located behind the screen printing machine in the SMT production line.

  1. Reflow Soldering

Its function in SMT manufacturing line is to melt the solder paste so that the surface mount components and the PCB board are firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the fully automatic SMT production line.
