  The release speed of solder paste printing is generally set to 3mm / s, too fast is easy to damage the shape of solder paste, and the solder paste printer is allowed to be set to 0-20mm / s. so what is the separation time between PCB and template? That is, the time required for the substrate after printing by SMT solder paste printing machine to leave the steel mesh at the stripping speed. If the time is too long, it is easy to leave solder paste at the bottom of the steel mesh. Too short time is not conducive to the standing of solder paste- Generally controlled at about 1s. The automatic solder paste printer controls this variable with the demoulding length, which is generally set to 0.5 - 2mm, and the allowable setting range is 0-10mm.

Solder Paste Printer

 

After the solder paste printing, the instantaneous speed of the steel plate leaving the PCB, that is, the separation speed, is a parameter related to the printing quality, and its adjustment ability is also a parameter reflecting the quality of the printing machine. It is particularly important in the precision printing machine, and the early printing machine is constant

Fast separation, the steel plate of the advanced printing machine has a small stay process when leaving the solder paste pattern, so as to ensure a good printed pattern. Affect the forming of printing solder paste, thus affecting the printing quality of printed circuit board, which may lead to solder joint connection and less solder and solder beads.
