I am looking for an industry standard �stock� note to place on our printed circuit board assembly drawings that will capture a level of cleanliness for an IPC-A-610 class 2 board assembly. I�m looking for some quantitative spec for cleanliness that w

Selective soldering machines are a good way to "finish automation", if the design of the PCB is conducive to the application with just a few components to solder. Your points are good. A decision matrix for selecting a machine might also include:

Hi Excellent. You are right that many areas due to ESD or cleanliness requirements would not be appropriate for Walkmans, personal CD players and such. YiE, MA/NY DDave

Try to see J-STD-001 Chapter 8.Cleaniness Requirements. Also you could info also on ASTM D5127-99. Rgds

Michael, You're right, of course. A major mis-type on my end. What I meant to say is that no-clean fluxes are designed to not _require_ cleaning to meet industry cleanliness standards. Cheers ..rob

Tough to say, but ... Chlorine: Many fluxes contain chlorine. Sulphur: Many solders and paper packing materials contain sulphur. Sodium: No idea. IPC-J-001 talks to board cleanliness and specifies criteria according to the cleanliness test met

We do cleanliness testing each morning using a Zero Ion tester. Our pass/fail number is set at 37ug/square inch NaCl. We are rarely above 10ug/square inch NaCl. We use Aqueous flux. Our inline washer has a prewash (70psi@130 degrees F), wash (?psi),

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

IPC-J-STD-001E in regards to Ionic Cleanliness standards states less than 1.56 µg/cm² of total NaCL. Assuming a typical electronic process which involves smt, wave, and post-hand soldering and uses NO-Clean flux throughout all process, is it typi
