The cleaning of PCB assemblies can be performed using either aqueous or solvent based processes. These depend on a range of parameters (safety, chemistry, cleaning process, environment, substrate and soil type) as well as PCB design and reflow temperatures. Types of flux residue vary from process to process and even no-clean fluxes leave a residue. No single chemistry proves the answer for every situation. The aim is to achieve consistently clean PCB surfaces and under-component areas, free for unwanted flux and other residues – for reliability and repeatability. 

Assembly cleaning processes using aqueous cleaning chemistries include 

  • aqueous batch cleaning – spray in air
  • aqueous batch cleaning – immersion
  • aqueous inline cleaning 

Stencil cleaning using dedicated automatic equipment complements other stencil cleaning methods, including under-stencil wiping and manual or semi-auto cleaning to help avoid unwanted residue on stencils that can lead to print problems and defects.  There are 4 main automatic cleaning processes:

  • immersion ultrasonic cleaning, water rinse
  • Immersion ultrasonic cleaning, no rinse
  • Spray-in-air, water rinse
  • Spray in air, no rinse

Fraser Technologies can help ensure compatibility between chemistries, processes and equipment to ensure optimal cleaning results. New challenges are always on the horizon, and our aim is to meet the changing needs of the electronics sector and help deliver cost effective, safety-conscious and eco-friendly solutions.
