Either you are using a normal or semi-manual stencil printer then you should look at the speed of the squeegee. It should be near about 25 millimetres per second. If you are looking for a complete detail then you can learn more from here. This blog post will guide you about each and every step.

Hi Martin,

Thanks for quick reply.

Please help to share the recommended solder profile as well ( REFLOW). Thanks.

Some things to consider are the following:

Support under the PCB during the paste printing
Support under the PCB in the reflow oven
Stencil thickness
Hole size on pads
Paste type/size (T3/T4T/T5/T6 etc.)

At our lab, we have 80µm thick stencil with 15% reduction on all pads and use T5 solder paste.
