I am not aware of any correlation that temperature and pressure is a good indicator of board cleanliness. You can drop a thermometer into the tank to verify the temperature. Water cleanness/Ph are more important. If you are truly worried about board

I need to set a cleanliness limit for our incoming boards. I know that some people use 14-10 microgr. sq. in. But how can I determine what is best for me. Can anybody tell me if there's a standard for this. Right now we are using an Alpha Ionograph

The industrial standard is follow the R.O.S.E test as a guideline per J-STD-001 and the limit is 10ug/sq. inch. Different tester with different equivalent factor with the ROSE and you can refer back to the manual, the Zero Ion tester with equivalent

Greetings All, Anybody out there experiencing white residues after cleaning? We currently use a batch cleaner to clean water soluble fluxes. this cleaner makes its own DI water by means of carbon and resin tanks. After cleaning there are residues

It would help to run a carbon, anion, cation, mixed-bed configuration with pure DI as the final rinse. IF your incomming water is really bad you can run a RO unit to "prepare" the water for ion exchange. Do you run omega meter or ionograph testing

Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani

If you eliminate this test, how would you monitor the cleanliness of your: * Bare boards * Components * Processes You probably could get a c of c from your board fab, but a c of c from the component suppliers would be burdonsome [and agruably useles

We are trying to deploy an Ionograph cleanliness tester and wanted to know what others are using as a standard test sample. My desire is to run the test on a weekly basis using the same medium complexity assembly. We plan to use the testing as a pr

I agree with DaveF's recommendation to see Foresight's website (www.residues.com). They have excellent Case Studies on display (for free). There is a good case study which references the results you can expect using a ROSE tester vs other control met
