- To remove surface oxides from PCBs and components to promote correct alloy formation
- To act as a heat transfer medium to ensure correct soldering temperatures
- Insert test piece. This causes a volume of test solution to overflow into a calibrated overflow tank for measurement (corrected to compensate for components if necessary).
- As the solution is pumped across the test piece via the measuring cell the rise in conductivity is monitored. The test ends either when a pre-set time limit (between 3 and 15 minutes) is reached or when the conductivity level rises less than 1 percent of the absolute value over a period of 48 seconds.
- On completion of the test, the results are processed and analysed by the computer and may be viewed on-screen. The results are stored on the hard disk for future use and for comparison purposes.
- The overflow chamber empties and the tank is replenished and regenerated for further tests.
