Spletratios of 0.66 and aspect ratios of 1.5 were never exceeded. The land pattern on the PCB should be 1:1 to the land pads on QFN package. Stencil thickness of 0.125 mm is recommended for 0.5 mm dual-row QFN packages. A laser-cut stainless steel stencil with electro-polished trapezoidal walls is recommended to improve the paste release. Splet09. dec. 2015 · The art work is the photographic pattern used to control where the copper is going to remain on the PCB stock. With positive artwork, the image is black where the copper will stay, and with negative artwork, the image is clear where the copper will stay. The pattern is transferred to the sensitized PCB by a process called “contact printing”. how to make a leather phone pouch https://germinofamily.com
