StencilWasher LDO Stencil Cleaner

StencilWasher LDO Stencil Cleaner

Low-discharge ultrasonic cleaning for stencils and misprints.

The StencilWasher LDO uses controlled ultrasonic energy to remove solder paste from stencils, screens, and misprints—while recycling wash solution to reduce waste.

  • Low-discharge system: filtered rinse with recirculated wash solution
  • Ultrasonic cleaning (40 kHz): effective yet safe for fine-pitch features
  • Sweep technology: protects delicate components and wire bonds

Reduced Wash Solution Costs

The StencilWasher LDO minimizes operating costs with a built-in filtration and recirculation system.

  • Wash solution reuse: filters and recirculates for extended life
  • Lower consumption: reduces need for fresh chemistry
  • Less waste: minimizes disposal requirements

This system improves efficiency while lowering overall operating expenses.

Advanced Ultrasonic Cleaning Technology

The system uses controlled ultrasonic energy to remove solder paste from stencils, screens, and misprints.

  • 40 kHz ultrasonic cleaning: effective yet gentle on fine features
  • Removes dried paste: ideal for fine-pitch stencils
  • Sweep frequency (37–43 kHz): protects delicate components

This ensures thorough cleaning without risking damage to wire bonds or sensitive structures.

Integrated Wash, Rinse, and Dry System

The StencilWasher LDO combines washing, rinsing, and drying in a controlled, low-discharge system.

  • Programmable cycle timer: consistent process control
  • Temperature-controlled heating: optimized cleaning performance
  • Low-discharge design: recirculated wash + filtered rinse water
  • All-stainless construction: durable and reliable

Additional tools provide flexibility for targeted cleaning and drying.

  • Rinse wand: precise manual cleaning
  • Air knife: controlled drying of specific areas

Large Cleaning Capacity

The system accommodates large stencils, screens, and misprinted PCBs in a fully immersed cleaning process.

  • Max size: up to 29" × 29" (736 × 736 mm)
  • Full immersion: complete, uniform cleaning coverage
