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

Are you running any type of vibratory wave on the Vitronics as opposed to the electrovert? How about any turbulent wave differences if any? The only time I have ever flooded boards in fixtures is when the seal is broken or run an excess amount of v

Addressing the issue "Will cutting change the readings?" Very Very Doubtful. Here is a link to a helpful guide. http://www.omega.com/techref/ Enjoy, cal

Justin, you will find measuring equipment at http://www.omega.com All sensor signals are in uV or mV and require a signal amplifier. If you get an amplifier with display, you can program a conversion factor for mV to board stretch and it will show a

Mike: An omega meter has very little to do with ion chromatography. * IPC TM-650, 2.3.25B, Detection and Measurement of Ionizable Surface Contaminants is a process control method that washes boards with an isopropanol / water solution and measures

Well, I don't know if you want to muck around this much, but I bought a GE (Chinese made, of course) toaster oven with convection fan. Nice big glass door in front, you can use it in bake, broil, toast or convection oven mode. The only thing missin

Three popular methods: Resistivity of Solvent Extract (ROSE) Test Method IPC-TM-650 2.3.25: The ROSE test method is used as a process control tool to detect the presence of bulk ionics. The IPC upper limit is set at 10.0 *g/NaCl/in2. This test is p

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
