Product portfolio

IC / leadframes

Plating chemicals leadframes
  • Innovative solutions for leadframe roughening, tin plating, ultrathin Ni/Pd/Au and high-speed silver plating
  • Highest MSL level performance
  • Whisker prevention
  • Low-to-zero free cyanide high-speed alternative for plating matt silver over leadframe surfaces

Connectors

Plating chemicals pretreatment electric industry
  • Innovative solutions for gold/gold alloy plating, palladium/palladium alloy plating, silver plating, nickel plating, tin plating and nickel gold plating
  • Pure tin layers with low internal stress, excellent solderability and minimal propensity to whisker
  • Robust systems allowing for wide variation within most significant plating parameters

Pretreatment

Plating chemicals for connectors
  • Innvoative solutions for cleaning, anti-immersion and deflashing
  • Processes for perfectly cleaned and activated metal surfaces

Post-treatment

Plating chemicals posttreatment electronics
  • Innovative solutions for anti-discoloration and anti-tarnishing, anti-corrosion, bleed-out prevention, stripper and belt stripper
  • Processes to inhibit discoloration of tin plated layers
  • Excellent wettability and solderability of tin plated surfaces after steam aging and pressure cooking

“We have carried out an extensive and methodical comparative study to evaluate and help visualize our deflashing performance. We have used the results to successfully develop the new Deflash GR1 process.”
