Verinas

Application

Flux residues dynamic solubility testing and comparison
Statistical process control of cleaning process according to J-STD-001 Am.1, par. 8
Validation of changes instead of ionic contamination measuring
Cleaning process optimization
Cleaning machine capability studies
Cleaning process diagnostic

Use flux jelly of the same paste as you are using at assembly Alternatively, you can centrifuge your solder paste
Use PBT GLASS TEST BOARD

Fill the gaps under the chips on GLASS TEST BOARD with flux jelly
Reflow the GLASS TEST BOARD
Run the cleaning process with GLASS TEST BOARD
Evaluate remaining residues under chips with magnifier, microscope, or AOI VERINAS

Visualisation of cleaning under components
Test system to fit PBT GLASS TEST BOARD
Transparent base (glass) allows precise measurement of cleaning progress under components
Situation after cleaning is scanned through glass
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

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

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“
