Solder Paste Printing
HCH-PCB SMT workshop has automatic solder paste printing machine to print the solder paste on the strencils.
Strictly control solder paste printing
Generally ,the solder paste printer is composed of plate loading, solder paste, imprinting, and PCB transfer.
Its working principle is: fix the PCB to be printed on the printing positioning table, and then use the scrapers of the printer to print the
solder paste or red glue on the corresponding pads through stencil.
The transfer station is input to the placement machine for automatic placement.
1.What is solder paste Printer? And how does it work?
Printing solder paste on a PCB and then connecting electronic components to the PCB through a reflow is the most commonly used
method in the electronics manufacturing industry. The printing of solder paste is a bit like painting on the wall. The difference is that
in order to apply the solder paste to a certain position and control the amount of solder paste more accurately, a more precise
special steel plate (stencil) must be used. Control the printing of solder paste. After the solder paste is printed, the solder paste here
is designed in the shape of “田” to prevent the solder paste from being too concentrated in the center after melting.

3. The function of solder paste printing
Solder paste printing is the basis for the quality of the solder on the PCB, and the position of the solder paste and the amount
of tin are of importance.It is often seen that the solder paste is not printed well, causing solder short and solder empty.
