Re: What is ion contamination? Specs are C-7000 & Q1000-119 - Material is Ultradur B4
Does the contamination test only for ion?
Yes, due to the principle of the measuring system. The measurement of the ionic contamination is carried out by immersing the test component into a test solution, usually a mixture of isopropanol and deionized water, to wash off the "contamination". The dissolved ionic contamination results in a change of electrical conductivity of the test solution. The conductivity is measured in a measuring cell.
Does the test able to test for organic component such as silicon...?
No, just changes in conductivity.
What unit the test result will gave by the contaminometer?
The conductivity is measured in S (Siemens) or in this case ?S (micro Siemens). However, the result is converted into/ expressed as ?g NaCl equ./cm?.
What is the pre-caution or PPE or type of packaging to protect the part from ion contamination?
If you don't know the degree of possible ionic contamination of your part, thinking about the packaging would be my second priority. First of all I'd find out what we're talking about, taking a part out of shipping, maybe even packed, and get it tested. However, since a contaminometer can easily cost around 20k EUR upwards (right now about the same in $), you should try and find a lab near you for doing this.
Does it means that the environment temp and humidity need to control at certain acceptance level?
Unless your production facility is near the sea side, salt or ionic contaminants in the air shouldn't be a reason for climate control.
