Cleanliness and Surface Qualification

We analyze your process to the µm!

At ZESTRON‘s Analytical Center, you have the opportunity to test your entire cleaning process according to international standards such as IPC, MIL or J-STD using a multitude of analytical test methods.

The available processes can be divided into visual, chemical and physical test methods. Thus, all cleaned substrates, such as power modules, PCBs, stencils and tools, as well as the quality of your cleaning bath itself can be analyzed using various techniques.

We provide:

  • Analytical methods to qualify the surface cleanliness according to J-STD001F
  • Detailed written technical reports
  • Analysis of possible failures induced by residues
  • Recommendations for corrective action or optimization

The following analytical methods are available:

  • Ionic Contamination testing for monitoring of cleanliness level
  • Ion Chromatography for process validation and risk assessment 
  • High resolution surface analysis with digital and optical microscopes up to 1000x magnification
  • Qualitative thermal analysis by determination (qualitative and quantitative) of anions, cations and weak organic acids
  • Surface energy via contact angle measurement or ink test for bond and mold ability
  • Surface resistance measurement for signal integrity
  • ZESTRON® Flux Test to indicate local distribution of flux activators for corrosion and leakage risk assessment
  • ZESTRON® Resin Test to visually identify local distribution of resin-based residues for coatability and bondability
