Laser cut step - stencil

Is it possible that the squeegee may get stuck in the step area?

With our special technology, which is a combination of a laser cut and laser welding process, we guarantee smooth transition on the patch edges. The squeegee blade can easy adjust to step heights or depths. 

Are design rules available for step stencils?

There are design guidelines available form IPC for step stencils, see IPC-7525B (2011), which can be ordered direct through IPC.org or through FED (Fachverband Elektronik-Design e.V.)

Which step heights/depths can be realized?

Generally are step height differences possible with our technology to max. 2 mm. However

design guidelines for the printing process should be considered, especially the distances from the step edge to the aperture in the step area. Eventually it is necessary to adjust the squeegee blade of the printer as well. As a thumb rule you can say: for every 25µm step height difference, the distance in the step area to the aperture might be 0,9mm. That means a step height difference of 0,1mm causes a distance in the step area from the step edge to the aperture of 3,6mm. In most cases a step height differences of more than 80µm is rarely applied in the SMD-Technology
