Iblueboard Cross-sectioning

Quality assurance – Microsection analysis

Microsectioning or called crosssection analysis is a destructive sample testing procedure

Used throughout the PCB fabrication industry.We make regular microsections for every

Model PCBs.As they allow us to see inside the PCB and make prcise measurements to

Check our production process and to confirm the quality of the finished PCBs.

We use microsectioning to check the quality of:

PCB base material

  • Inner structure of multilayer boards
  • Plating Thickness
  • Solder mask
  • Component mark
  • Circuit
  • Holes
  • Profile
  • Surface finish thickness

Microsectioning procedure

  1. Select the appropriate PCB or quality-control test coupon
  2. Cut out a piece for sample
  3. Embed the sample in resin
  4. Grind down to a flat surface
  5. Polish and etch back if needed
