Simon, The equivalence factors were used to scale the values measured by ionic testing equipment to the values measured in the standard manual method. There is a good write-up by Bill Kenyon in this Technet Post describing the creating of the facto

Surfactant. A synthetic detergent made from petrochemicals that lowers the surface tension of water and allows better cleaning in small spaces. Do you have a cleaning issue that requires you to use a surfactant? If so, be aware that you must clean

The Omegameter (or Ionograph) detect contamination by measuring the conductivity of the solution used to extract the board. This conductivity number reflects the sum of all of the ionics in the extraction solution. Unfortunately, we can't sort out th

If the flux is already eating thru Cu it must have been some time since the boards were soldered with the OA flux. Ionic contamination testing (with OmegaMeter or IonoGraph)can be done to find contaminated boards and cleaning the boards can be done

Yes, the OmegaMeter and IonoGraph are test equipment to measure ionic contamination. Either of those units should enable you to sort your inventory boards. for more info about this equipment, go to: www.cooksonee.com/products/scs/CoatingSystems/Ionic

Hi, Is there a standard expiry date for a ROSE Test Instrument Like Ionographs, Omega Meters, Zero-Ion etc.? How can I verify if my OmegaMeter 500 which is almost 20 years old is providing me reliable data during testing? Note that the equipment is

A fairly painless method for monitoring cleanliness is Resistivity Of Solvent Extract [ROSE]. Equipment is: * Omegameter * Ionograph * Ion Chaser [Zero-Ion] Anyone who desires to use an Resistivity Of Solvent Extract tester should read EMPF repor

Need help with an 1994 vintage Alpha Metals Omegameter 700 (OM700) Ionic Contamination tester. These machines apparently came with a unique password to access the configuration. The original factory-configured password has been long lost. I'm wo

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

Larry: Cookson spun Alpha's instruments (omegameters and such) into its specialty coatings group, you know with Paraline and all that. Makes sense to me. Of course, I don't connect with the whole Cookson approach anyhow, but they have money and th
