Cross sectioning

Sample preparation by Cross-section is a very powerful tool for failure analysis about how material, product plated or assembled. It can provide more accurate for measuring lamination or plating thickness. The measurement can be done on calibrated Optical Microscopy or SEM/EDX. The application of cross-section is for:-

  • Determine coating thickness or coating continuity
  • Measurement of mixing layer or diffusion of two materials such as Intermetallic layer
  • Other failure analysis evidence like crack initiation, foreign material, void in solder
