thanks for your response. I have a couple of reasons for evaluating this. 1) We recently purchased an ionograph to replace an outdate Omega meter. Correlation is required and in discussing this with several people, most wondered why we checked if we

Hello We are currently getting Proto's of legacy product built up in Europe. Our current supplier uses a spec of 14 micrograms or less of sodium chloride per square inch as measured on a omega meter. THe product is Industrial and I am not sure do we

Hi, We will run a no-clean wave solder process to assemble TV boards. What about incorporating a ROSE Test equipment (Ionograph, zero-ion, Omega Meter) in the process? Is it recommended, helpful or unnecessary? I�ve read about the use and limits of

We recently had our customer report a component failure trend of a few percent. Analysis indicates wire bond failure internal to a d-pak caused by what appears to be chlorine contamination. We're running a lead free process with aqueous wash. 700 co

You should talk to your paste/flux manufacture! They will provide the best instruction for this. The norm is typically 130-145f, speed 2-4f/m I always push for slower… the slower the cleaner/drier (in theory!), if you have an ICOM, Omega meter, ionog

Neither the Omega meter nor the IC are officially "destructive" tests, but everywhere I worked we treated them that way. The boards were scrapped after the test. The Omega meter can be tested at elevated temps, but the IC sample is extracted at ele

We are using the omega meters to determine the solvent extract conductivity. The book is refering to standard MIL-P-28809 who specifies a 14 ug/sq. in. of Na/Cl limit. The past owner of our machine was setting the pass/fail limit at 3.6 ug / sq. in.

Jim, you may need to look with different paste instead of the cleaning solvent. Please advise what is the paste which you currently using? Beside, when you talking about the board stayed in hot area, is it a drying area or the cleaning zone. If it

If No-Clean flux does not need to be cleaned, then why do I get readings of up to 27(ug NaCl/sq in) on boards that are not washed, up to 23.4(ug NaCl/sq in) on boards washed with DI water only and from 1.2 to 10.1(ug NaCl/sq in) on boards washed with
