Technical Cleanliness: Extraction of particles and analysis

Even the smallest amount of residue may increase the risk of failure on electronic boards significantly. Therefore, when producing electronic boards, you should intend to keep the amount of particles with a potential risky size and type as low that no failures occur during the production process nor when the board is applied in the field later on. By using specific extraction and analysis techniques, particles on the board can be quantitavely and qualitavely measured (based on standard VDA19 / ISO 16232) to evaluate the failure risk. Furthermore, by using this method the influence of particle residues on failure can be evaluated, where applicable.
