My OMEGA Meter 600 is no nlonger operational. The new unit that I was looking at is the Ionograph 500. Does anyone have input on the Ionograph, or has anyone ever worked with both the Ionograph and the OMEGA600.

Chemistries are limited for WS Mask. Try looking/changing other components, trying different flux types is easy, identify water cleanliness, is it ionic/no-ionic...probably is benign. Could be a plating reaction which is tough to investigate. Call

New to using Ion Chromatography (IC)testing to understand cleanliness of PCB. I've been informed that one method to monitor is to use R/O/I. What is R/O/I?

There are only two (2), but the qty and size do not really prohibit hand soldering and we would still need to clean around their leads manually to meet the cleanliness spec.

Third, if component placement is off, fix the machine (i.e. calibrate, check cleanliness of lenses and sensors, damaged nozzle) and not the CAD locations.

An ionic contamination tester should meet industrial cleanliness specifications including MIL-STD-2000A, MIL-P-28809, J-STD-001 and Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25

Just wanted to ask what is the correct test method i need to do to ensure that my cleaning solvent is still OK to use. This is in particular for stencil cleaning,carriers, pcb etc. I am using a jet cleaner with recirculating solvents.

Voiding usually is caused by oxidation/impurities on the plating of part and or PCB. I know it is gold, but did you run any analysis for cleanliness of part plating? Couple of pictures will help everyone.

The issue is not the cleanliness of your in-bound water. The issue is the cleanliness of the board your customer receives. Look at J-STD-001C, Para 8, "Cleanliness Requirements". The end product cleanliness is the end result of your: * In-bound

Are you talking about bare board cleanliness or assembly level cleanliness? Bare board cleanliness is still primarily measured by resistivity of solvent extract (ROSE) using instruments such as Omegameters and Zero Ions. What is considered as "acce
