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

Yes, providing your: * Inbound material does not compromise your process. * Soldering processes apply the proper amount of flux and activate it properly * Material handling does not contaminate your boards Recognize that the IPC requirements of less

Rich An excellent question and one which is often totally ignored. If you wish a "no-clean" flux to be as safe as it possibly can be, the PCB and the components must all be contamination free (ionic and non-ionic). Only then can you be sure that the

Military and most commercial standards requires post-soldered boards to measure less than 10 �g/in of NaCl (14 when using an Omegameter, 20 on a Ionagraph, and 37 on a Zero-Ion). As Dave stated, 6.5 �g/in of NaCl is called out in Mil-P-55110 for ba

Hello, does any one please can tell me if any Standard says how much is the Total Ion Contamination ( ugr/NaCl sqcm equivalent, Br- in particular way) allowed on Connector surface/body ? (ie. DIMM connectors, and similar). Many Thanks in advan
