flat vector infographic illustration, clean thin black outlines, navy blue and orange flat colors, plain white background, no gradients, no photorealism, minimal corporate icon style. A long horizontal wave soldering machine, industrial conveyor line with visible zones left to right: flux sprayer, preheater, an open maintenance hatch in the center showing a rectangular metal solder pot filled with wavy shiny molten metal and a fountain nozzle, and a cooling zone. Beside the open hatch, a technician crouches low with bent knees, wearing protective gloves and safety goggles, dipping a long flat metal scraper skimmer tool into the molten metal tank to skim dross off the surface. The tool is a flat skimmer dipped into the tank, NOT a broom; the technician is NOT sweeping the floor. Small round flux tank on the side, signal light tower on top. Two-tone navy and orange flat icon style, thin outlines. Mehr sehen
