The flat side of the tool should be used on larger boards and stencils to ensure an even film thickness over all pads. For small stencil sizes (less than 50×50 mm), you may find it easier using pressure from just one finger as opposed to a whole hand for applying the paste.

WebThe copper trace width primarily determines the solder mask thickness. You require about 0.5 mils of mask over the traces. A liquid mask brings unpredictable consistency to a PCB. It can be as thick as 1.2 mils over blank laminate regions and as thin as 0.3 mils over complex features, like the circuit knee.
