Necessity of ROSE in commercial quality processes

Electronics Forum | Sun Feb 26 13:49:18 EST 2006 | masrimhd

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

ROSE testing pass / fail

since IPC-J-STD-001 RevH obsoleted the 1.56ug/cm2 UCL of ionic contamination tester in testing using ROSE test, how do you define the acceptable limit per PCB assembly? thanks

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

After changing mod codes 50,51 and 54,55 respectively on the HHT I will then goto ccconfig.sys file in the central controller software and manually enter in the new mod code values. I do not do any uploading/downloading of mod codes through database

Ion Chromatography (IC) qualification

Electronics Forum | Thu Apr 14 09:39:41 EDT 2011 | blnorman

ROSE has the advantage in that it does have a specific acceptance criteria (J-STD-001), whereas the IC does not. ROSE allows the test to be run at ambient or at an elevated temp, IC requires the component/board/assembly to be "cooked" for 1 hour @ 8

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

Hi there - unfortunately, there are no good cleanliness specs available mainly because clealiness requirements are case sensitive - you should talk to Terry Munson at 765-457-8095 - he can definitely give you advice on Ion Chromatography, SIR, ROSE t

Electromigration Testing

This may sound dopey, but it may be the answer to your question. ROSE testers from different suppliers produce different results. Look at MIL-STD 2000. Based on Table VII, you find the following upper control limits (micrograms NaCl / sq. in.): * M

Cleaning OA flux with vapor degreaser

Resistivity Of Solvent Extract [ROSE] is a bulk ion contamination [BIC] test method. It should thought of as a process control tool used to assess ionic contaminants. Don't consider it an acceptable tool for establishing 'GO-NOGO' limits. The stan

SIR starting point...?

First, SIR data is heavily dependant on the test pattern selected. Be very careful when comparing the results of resistance readings taken from different geometric patterns. Second, if yer talkin': * Bare boards, yupper. * Finished assemblies impor
