Problem-Solution Intro<\/b><\/strong><\/h3>\n

Managing the “Hydraulic Hurdle” in Wet Processing.<\/b><\/strong>\u00a0When a PCB panel leaves an etching or developing tank, it carries a film of chemicals that can puddle and cause uneven processing. Standard flat rollers just squeeze the liquid; our SN:6-3<\/b><\/strong>\u00a0Grooved PP Roller<\/b><\/strong>\u00a0activeley channels<\/i><\/em>\u00a0it. This is a critical component for equipment manufacturers looking to reduce cross-contamination<\/b><\/strong>\u00a0and improve the uniformity of the PCB surface treatment.<\/p>\n

Precision-Machined Drainage Channels<\/b><\/strong>\u00a0We don’t just mold these; we precision-machine the grooves into high-grade PP:<\/p>\n

    \n
  • <\/b>V-Groove & U-Groove Geometry:<\/b><\/strong>Designed to break the surface tension of the liquid, allowing it to drain toward the sides of the conveyor line.<\/li>\n
  • <\/b>Reduced Contact Surface:<\/b><\/strong>The grooved design minimizes the contact area with the PCB board, reducing the risk of “suction” that can cause thin boards to wrap around the roller.<\/li>\n
  • <\/b>Inertia to Chemicals:<\/b><\/strong>The PP body ensures the groove edges stay sharp and functional, resisting the “rounding off” that happens to softer materials in acidic baths.<\/li>\n<\/ul>\n

    • <\/b>Variable Pitch & Depth:<\/b><\/strong>We can machine the grooves to match your specific drainage flow rates.<\/li>\n

      Main Application Scenarios<\/b><\/strong><\/h3>\n

      In any high-volume Etching or Developing line<\/b><\/strong>, “chemical drag-out” is a yield killer. The SN:6-3 is specifically built to break the surface tension that causes liquid to puddle on the board. Unlike flat rollers that just push chemistry around, these machined grooves act as active drainage channels. We see these most often at the exit of Etching machines<\/b><\/strong>, where they funnel aggressive acids away from the panel center to prevent “over-etching” at the edges.<\/p>\n

      \uc744 \uc704\ud55c LCD Glass Washing<\/b><\/strong>, the grooved profile is a lifesaver. It allows rinse water to flow under<\/i><\/em>\u00a0the glass substrate, flushing out micro-debris that would otherwise get trapped and crushed by a standard roller. It\u2019s also the go-to for FPC (Flexible Circuit) lines<\/b><\/strong>; the reduced contact surface prevents that “suction effect” where ultra-thin boards stick to the roller and wrap around the shaft, causing a catastrophic line jam.<\/p>\n
