SMT pick and place machine,pcb assembly,fully automatic pick and place machine	,QL41,QL41 liteplacer,
smt machine,

First step use solder paste mixer

Automatic rotation for softening solder paste

Second step use stencil printer

suggest the semi-auto model machine

Apply the softened solder paste to of the stencil .Then press the button of the machine.Scraper automatically brushes solder paste.

Third step use led pick and place machine

Set the LED board, Import the coordinate file or
edit the position in the software
then Set the position of Feeders and set pcb mark point .
The machine starts automatic placement .

Forth step use Inspection Conveyor

Put The LED board into the conveyor for inspection .
Adjust the transmission speed of the conveyor.
Automatic transfer to reflow oven.

Fifth step use Reflow oven

You need to preheated to a suitable temperature before use .
Automatic transferfrom the conveyor and welding .

Sixth step use LED strip cutter

LED cutter machine to cut the puzzlepanels into

smallstrips for LED lamp assembly

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.


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.
  2. 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.
  3. 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.


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.
