Positioning for stencil printers for circuit board assembly

A magnetic application from our customer: positioning for stencil printers for circuit board assembly.

Dear Sir or Madam,
Here is some information about my magnetic application.
I find the application examples very useful. A page like this with the appropriate keywords would certainly have saved me a lot of research, as I didn't know these things were called "pot magnets." :-)

Positioning for stencil printers for circuit board assembly

My application:

• A steel sheet with cutouts is positioned over a circuit board.
• Solder paste is applied using a squeegee.
• After removing the stencil, small "islands" of solder paste are located at the points where soldering is to take place.
• The components are placed in this paste.
• After assembly, the circuit board is placed in a special oven.
• The solder paste melts and thus solders the components to the circuit board.
• The original fixing tool for the printer is quite large and inflexible.

The small pot magnets are therefore ideal for circuit boards with an outer contour and smaller Prototypes.

The following were used:

• Neodymium pot magnet Ø 6.0 mm with socket M3 holds 0.5 kg
• Neodymium pot magnet Ø 10.0 x 4.5 mm with socket M3 holds 2.5 kg
