Cleaning during manufacturing process:
An ultrasonic cleaner is used; probes are placed in an alcohol solution in a beaker. The beaker is then placed in an ultrasonic bath for a period of 10 to 30 minutes.
Tin contamination removal:
Option1 – AQL Cleaning plate and Ultrasonic brush:
Place an AQL cleaning plate on the probe block and brush the probe tips with a standard, or preferably, ultrasonic toothbrush.
Option2 - Acid Solution Process:
In an application where deposits of tin are adhering to the plunger tips we suggest the use of a ‘mild ‘ nitric acid. The gold plate on the probe is inert and will not react to the acid. Tin is a soft material and will transfer to the probes under most circumstances, but should be removed by the nitric acid.
Place the probes in a mild nitric acid solution in a beaker, then place the beaker in the ultrasonic.
The Micron probes are cleaned using a commercial grade ultrasonic cleaner. These machines use a piezoelectric crystal to agitate the cleaning solution.
Experimentation with nitric acid baths is currently being conducted further data on this cleaning process should be available soon. Every effort is made to accurately reproduce a contamination of tin deposits on the plunger tips of the Micron probes.
It is however unlikely that we can reproduce the exact material that is being deposited under a production test environment at a customer location. Should it be necessary, customers can identify and supply a sample of the tin material being used at their facility.
