First, let me say what I always say: a good chem-etched stencil will print fine pitch. Chem-etch brings trap to the side walls because its a physical by-product of the process. Because they are less expensive you can add electropolish and still save

Start with targets based on the stencil thickness (for height) and stencil thickness times the aperture size (for volume). * Set reasonable upper and lower control limits (+ 25% and –25 % of the targets, for example). * Next, check the printer set-u

Niedernhall, 2009, August 4 – PCB expert Würth Elektronik’s printed pulse resistors achieved the till now claimed impossible high-voltage range of 200,000 V. That has been realised once more by the Würth Elektronik-owned “smart-conductive polymer thick film systems”, outstanding due to a wide variability of resistances.
