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),

Hello, I have been tasked with updating our PCB cleaning sytem, of which I know little about, and could really use some advice. We are a small company and we hand solder our electronics to IPC standards. Our electronics are mission critial communic

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

Pascal: Responding to your questions: 1 Do we have to dry the PCB after cleaning (sic)? Generally, nothing says you have dry the PCB after aqueous cleaning. Along this line, I received several thoughtful responses when I posted a similar thread.

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

If you're looking for PWB cleanliness , please consider one surface treatment other than HAL (i.e HRF-heat resist flux). HRF is a very inexpensive and effective process that your board manufacturer can provide you to meet your requirement. For gold
