Test Process Steps With Verinas
 

TEST PROCESS STEPS WITH VERINAS

  • Use flux jelly of the same paste as you are using at assembly
  • Alternatively, you can centrifuge your solder paste
Flux Injections
  • Use PBT GLASS TEST BOARD
PBT-Glass-Test-Board-Both-Sides
  • Fill the gaps under the chips on GLASS TEST BOARD with flux jelly
Reflow the PBT Glass Test Board
  • Reflow the GLASS TEST BOARD
  • Run the cleaning process with GLASS TEST BOARD
  • Evaluate remaining residues under chips with magnifier, microscope, or AOI VERINAS

AOI EVALUATION PROCESS

  • Visualisation of cleaning under components
  • Test system to fit PBT GLASS TEST BOARD
PBT Glass Test Board Test System
  • Transparent base (glass) allows precise measurement of cleaning progress under components
  • Situation after cleaning is scanned through glass
PBT Glass Test Board Test System Area
  • Precise colour filters are applied to get boundary between cleaned and not yet cleaned area under chips
  • Areas with remaining flux residues are measured by dedicated software
  • Test report is automatically generated using 400 values of flux residues under each chip

FLUX SOLUBILITY COMPARISON

  • Easy, fast and precise comparison can help to choose the best flux to cleaner combination
  • The results of all the readings is the „washing curve“ mapping the cleaning progress
  • Cleaning resistance is proportional to area in graph under the „washing curve“

CLEANING MACHINE PERFORMANCE TEST

VERINAS evaluates washing performance of your machine using GLASS TEST BOARDS

What influences washing performance:

  • type of machine, agitation
  • process parameters (temperature, pressure, time), usually controlled by machine
  • cleaning agent properties (concentration, bath life)

VERINAS together with GLASS TEST BOARDS provides fast:

  • process validation
  • subsequent cleaning process checking
  • identification of the cleaning performance critical spot in the washing chamber
  • comparison of various flux solubility, cleaning agents and cleaning machines
