Analysis Meeting Requirements of WEEE & RoHS Regulations
- Analysis of Hazardous Materials in Lead-free Solder and Planting -



  • It is possible to cope with the problem of segregation (dispersed conditions) of various alloy components by controlling solution species, acid concentration and dissolution time according to the alloy components.
  • It is possible to determine the amount of environmentally-regulated materials that are contained in the amount of 50ppm or more in various types of thin film of Sn by studying the measurement methods ICP-MS GFAAS and selecting a proper interference suppressor.

Analytical method

Pretreatment: Stepwise etching of plating film alone
