FK650 Pneumatic stencil cleaning machine
Key features include:
- Application Scope: Cleans diverse stencil types — SMT stainless steel mesh, copper mesh, wire mesh, microporous mesh, and wafer disks
- Energy Source: Exclusively uses compressed air, eliminating electrical components — ensuring intrinsic safety, no fire hazard, and suitability for explosive or high-ESD environments.
- Operation: Human-centered design with one-button start, enabling seamless, fully automatic execution of both cleaning and drying stages via controlled air pressure sequences.
- Fluid Management: Integrated closed-loop cleaning fluid recycling, minimizing consumption, waste, and operational cost. Low fluid loss enhances sustainability and process consistency.
- Automation Level: Fully pneumatic automation — no PLCs or electric actuators required; timing, sequencing, and pressure control are achieved via precision air logic valves and accumulators.
Cleaning Objects
Aimed at cleaning various types of stencils such as SMT steel mesh, copper mesh, wire mesh, microporous mesh, and wafer disks in the electronics industry; This equipment completely uses compressed air as energy source, does not use electricity, and does not have any fire hazards. It adopts humanized design and one-button operation to easily complete cleaning and drying work. It is a fully automatic operation from cleaning to drying process using air pressure. High-performance pneumatic fully automatic cleaning equipment; the cleaning fluid is recycled and the loss is low;
