I want to share my method of drawing on the PCB. Take a disposable syringe. After removing the needle, its internal cavity is filled with colored lacquer. And vypusnogo hole with little effort insert the burner Assembly from the rod of a ballpoint pen with the previously removed ball. Slowly pushing the plunger of the syringe can be safely applied on the degreased surface of foil Micarta (PCB) lines and “patterns” of any thickness and an arbitrarily complex configuration.
And there under the hands of the rod of a ballpoint pen — not a problem. Moglo after use the syringe without removing the needle from him, but only stachiw the tip on the sandpaper to 8— 10 mm length with subsequent polishing on fine emery cloth.
