ASYMTEK Viscosity Control System

ASYMTEK Viscosity Control System

Eliminate variability. Improve coating quality. Reduce rework. In conformal coating, even small viscosity fluctuations can lead to inconsistent coverage or defects—especially when ambient temperatures change or material lots vary. The ASYMTEK Viscosity Control System is designed to eliminate these risks by maintaining precise, stable coating viscosity throughout production.

By electronically controlling fluid temperature in a closed-loop, heated recirculating circuit, the system ensures repeatable coating performance from startup through continuous operation—even after idle periods.

Why Viscosity Control Matters


Uncontrolled viscosity changes directly impact coating thickness, fan width, and edge definition. The Viscosity Control System solves this by delivering:

  • Stable, repeatable coating results
  • Consistent fan patterns and film builds
  • Reduced solvent usage and emissions
  • Higher first-pass yield
 

This level of control is critical for manufacturers producing high-reliability electronics.

   

Key Benefits


  • Stable viscosity within ±1 °C for consistent coverage
  • Enhanced process precision with ASYMTEK Laser Fan Width Control
  • Uniform fan patterns with no warm‑up delays
  • Higher film builds in fewer passes
  • Reduced solvent usage and VOC emissions
  • Built‑in alarms to protect materials and prevent defects
   

How the Viscosity Control System Works


The system continuously heats and circulates conformal coating fluid through the valve and fluid circuit, maintaining temperature to within ±1 °C. Close range temperature sensors provide real-time feedback, allowing the system to react instantly to changes that would otherwise impact viscosity.

 

Operators define acceptable process limits within ASYMTEK EasyCoat® 6 software. If temperature drifts outside these limits, the system automatically generates an alarm—protecting product quality before defects occur.

 

If your operation demands tight process windows, high uptime, and consistent coating quality across shifts, the Viscosity Control System provides the control and confidence you need.
