Operating the stencil printer
Once the installation has been completed following the steps described on page 5, it is easy to place
successive PCBs on the placeholders.
BUT BE CAREFUL
Due to the fact that no PCB is exactly the same, it is advisable to check if the PCB pads still exactly
match the stencil holes before each print.
Let’s get started!
1.
Place a PCB on the place holders and close the printer as described before. Check if the holes
and pads are still aligned.
2.
Put the solder paste on the backside of the stencil with a spatula. Take care that the solder
paste is applied over the full width of the stencil cut-out.
3.
Place the squeegee behind the solder paste under a 45-60 degree angle and, in a zigzagging
motion while applying a little pressure, pull the squeegee to the front side of the stencil.
Make sure that all the holes in the stencil are filled with solder paste.
4.
Remove the remaining paste at the end of the stencil with the squeegee.
5.
Carefully open the printer and remove the PCB. It is now ready for assembly!
6.
For successive printing repeat from step 1.
Maintenance and care
Use the S1-01 only in a dry, clean location and strictly avoid aggressive environmental conditions
such as etching equipment. After using the machine, clean the machine with a solvent that only
removes paste and has no aggressive elements in it that could affect the machine or the stencil.
Note:
To prevent corrosion, slightly oil all metal surfaces twice or several times a year with resin and acid
free machine oil. (PTFE oil will be a good lubricant) No further lubrication is needed or advised.
